1. Observation: Pay attention to the dynamics of the road surface after milling (three to four days), and pave the milled and roughened road surface in time when paving conditions are met.
2. On-site mixing: During construction and production, a sealing slurry truck should be used for on-site mixing. Through the metering equipment of the sealing truck and on-site operation by a robot, it is ensured that emulsified asphalt, water, mineral materials, fillers, etc. can be mixed according to a certain proportion. , stir through the mixing box, and the paving thickness is not higher than the roughing depth.

Asphalt sealant is a material specially used for road crack repair. The following is a detailed introduction to asphalt sealant:
1. Definition and composition
Asphalt sealant is a road repair material made of asphalt or modified asphalt as the base material, with a certain amount of additives and fillers added, and processed by special technology. It usually has a black or dark brown appearance and is in a solid or semi-solid form.
2. Main characteristics
High adhesion: Asphalt sealant can firmly bond to the crack wall of the road surface to form a tight sealing layer to prevent moisture and other harmful substances from invading the road surface structure.
High elasticity: It has a certain elastic recovery ability and can adapt to the expansion and contraction changes of the road surface to prevent further expansion of cracks.
Weather resistance: After special process treatment, it has good weather resistance and can maintain its stable performance for a long time.
Convenient construction: The construction operation is simple and fast, without complex construction machinery, which reduces the construction cost.
3. Scope of application
Asphalt sealant is widely used in crack repair of various asphalt pavements, including highways, urban roads, airport runways, etc. At the same time, it can also be used for the maintenance and repair of asphalt surfaces such as bridges, tunnels, and parking lots.

There are many types of bitumen emulsifiers, and there are many classification methods. For specific classifications, please refer to previous articles. The raw materials required for the production of emulsion bitumen are: bitumen, water and bitumen emulsifier. High-standard emulsion bitumen requires adding additives and adjusting acid. According to whether acid adjustment is needed in the emulsion bitumen production process, it can be divided into two categories: emulsion bitumen that requires acid adjustment and emulsion bitumen that does not require acid adjustment.

The slurry seal truck is one of the main maintenance methods of highways. The slurry seal is made of emulsified asphalt as the binding material, well-graded mineral materials, fillers, water and additives, etc., mixed in a certain proportion. The slurry mixture is evenly spread on the old road surface to be treated with a sealing truck, and is firmly combined with the original road surface to form a new thin layer of asphalt mixture. So what preparations need to be done before construction? Let’s find out below.

Classification analysis of emulsion bitumen equipment is used to heat-melt bitumen. According to the actual cutting effect of mechanical equipment, it is loosened into a solution with demulsifier in the form of tiny droplets to form oil-in-water asphalt. Industrial equipment for lotions. Emulsion bitumen equipment can be divided into three types: portable, transportable and mobile according to the equipment, layout and maneuverability of the equipment.

Asphalt used to pave roads. It can be obtained by regular vacuum distillation of crude oil with appropriate properties, and can also be obtained by shallow oxidation of vacuum residue or propane deasphalting process. It can also be prepared by mixing asphalt of different duction and injection degree

After the rubber bitumen storage tank is cleaned, the wood chips are sent to the rubber bitumen storage tank, and the wood chips and the bottom of the rubber bitumen storage tank are wiped with wood chips. The dirt and wood chips in the bitumen tank can be weathered naturally. The rubber bitumen storage tank is not allowed to be damaged. Check the technical specifications of the underwater concrete processing equipment and ventilation equipment.
The bottom of the rubber bitumen storage tank drain pipe is discharged from the drainage pipe, and the waste water is discharged into the empty tank or other containers through the inlet and outlet and the self-draining pipe. Open the Shenzhen manhole into the plastic suction pipe and pave the Shenzhen manhole with asbestos to reduce the discharge of oil and gas. When manually pumping the bottom oil, two people should be operated to improve the labor efficiency of the workers and send the fuel tank to supervision.

Technical features of fiber sealing equipment:
1. Zero starting strong injection technology
With more than ten years of manufacturing history of asphalt spreading trucks and asphalt gravel synchronous sealing trucks, the zero-start strong spraying technology has been accumulated for many years. The combination of time-reliable hydraulic transmission components and Meitong’s control system can make the equipment instantly start from zero. Spraying starts in line, stable and reliable.
2. Duplex sealing structure
The sealing process of this equipment is a three-layer simultaneous and continuous construction process of one layer of asphalt + one layer of fiber + one layer of asphalt, forming a layer of interactive dense network winding structure, which fully meets the user’s construction requirements.

Due to the incorporation of a certain proportion of water into the slurry sealing mixture, it is easy to evaporate in the air. After the water is evaporated, it will become dry and hardened. Therefore, after the slurry is formed, it not only looks very similar to fine-grained asphalt concrete, but does not affect the visual appearance of the road. It also has the same technical properties as fine-grained concrete in terms of wear resistance, anti-skid, waterproofing, and smoothness. Slurry seal technology is used in highway pavement maintenance because of its simple construction technology, short construction period, low cost, high quality, wide application, strong adaptability, etc. It is an asphalt with both economy and high efficiency. Pavement maintenance technology is worthy of application and promotion.

Analysis of the necessity of emulsified bitumen equipment in modern road construction projects With the acceleration of the construction speed of transportation infrastructure, the construction standards are getting higher and higher, and higher requirements are also put forward for the use of emulsified bitumen in the closed layer of fly ash and the adhesive layer between the new and old ground.

How to reduce the energy consumption of emulsified asphalt production equipment is a concern of many users, and is also an issue that many manufacturers attach great importance to. Therefore, today Sinoroader, as a manufacturer of emulsified asphalt production equipment, would like to take this opportunity to share with you how to reduce the production of emulsified asphalt. Equipment energy consumption method.
Since emulsified asphalt appears as a finished product in emulsified asphalt production equipment, and the outlet temperature of ordinary emulsified asphalt is about 85°C, the outlet temperature of emulsified modified asphalt is above 95°C, so there is a lot of latent heat in emulsified asphalt, but emulsified asphalt The production equipment does not make good use of them, but directly enters the finished product tank, allowing the heat to be lost at will, resulting in a waste of energy.

Fillers used in emulsion bitumen equipment are generally divided into two types: chemically active and non-chemically active. In the production of emulsion bitumen equipment, it can improve the stability of the slurry mixture, speed up or slow down the demulsification speed, and improve the strength of the sealing layer. When adding chemically active fillers, the reaction and compatibility of the fillers with mineral materials and modified emulsion bitumen should be fully considered.

The selection of asphalt melting equipment should take into account factors such as the use environment, working conditions, and technical requirements. Common ones include hot oil heating equipment, electric heating equipment, and gas heating equipment.
Hot oil heating equipment is suitable for occasions that require long-term heating and high temperature control accuracy;
Electric heating equipment is suitable for small projects or occasions where temperature control accuracy is not required;
Gas heating equipment has the advantages of simple operation and low cost, but safety protection measures must be strictly followed.
When choosing, it is also necessary to comprehensively consider factors such as economy and environmental protection.

The difficulty of emulsified bitumen equipment itself, because general bitumen also has different classifications, in the production and processing of emulsified bitumen equipment bitumen concrete, it is necessary to pay attention to whether the common raw materials are the common bitumen and ensure the quality. Check the black antistatic tweezers of emulsified bitumen equipment asphalt concrete machine equipment emulsified bitumen equipment.
If the gap of the black antistatic medical tweezers bitumen concrete micro-powder machine of emulsified bitumen equipment is enlarged after long-term use, then we can adjust it and continue to process it. Emulsified bitumen equipment is a relatively simple difficulty.

Except for the first application, for enterprises whose block asphalt melting equipment license has expired and continue to engage in the production and operation of block asphalt melting equipment, they should apply for the relevant matters of postponement and renewal 45 working days before the expiration of the license.
The block asphalt melting equipment should first prepare the block asphalt melting equipment application materials, and then submit an application for postponement and renewal to the municipal environmental protection bureau. According to the production and operation of the block asphalt melting equipment and environmental protection work of the applicant enterprise, the municipal environmental protection bureau of the district where the block asphalt melting equipment is located will provide a review opinion in the form of a public document.

This set of mechanical equipment includes wastewater treatment, water storage tank, automatic water measurement and verification temperature control system, asphalt storage tank, asphalt external temperature system, hot water pump soap condiment system, soap storage tank, soap mixing pump, soap external It is composed of temperature system and measurement verification system, filtration system, hot asphalt mixing pump and measurement verification system, three-stage pipeline-type black antistatic medical tweezers, emulsified asphalt cooling system and retrieval machinery, and automatic control system for commercial tanks and electrical equipment.

Changing the color of asphalt pavement is an important project aimed at improving the beauty of roads, optimizing traffic signs and enhancing urban landscape effects. The following is a detailed introduction to the color change of asphalt pavement:
1. Color change method
Using pavement color change spray:
Spray directly on the original asphalt pavement surface to make the road surface look brand new.
This method is simple and fast to construct, with bright and lasting colors, and will not change the structure of the pavement.

Emulsified asphalt can be spread by mechanical spreading and manual spreading. Different spreading methods will have different effects on pavement performance, so it is very important to choose the right spreading method. At the same time, maintenance and management after spreading are equally important to ensure the safety and durability of the pavement.
Emulsified asphalt is a common pavement material that is widely used in road construction and maintenance. There are two main ways to spread emulsified asphalt: mechanical spreading and manual spreading. Mechanical spreading generally uses a special spreading vehicle that can quickly and evenly spread emulsified asphalt. Manual spreading is carried out by workers using tools such as brushes or rollers, which is suitable for pavement treatment in small areas or special areas.
Different spreading methods also have different effects on pavement performance. Mechanical spreading can quickly complete large-area treatment and spread evenly, which is conducive to ensuring the flatness and anti-skid properties of the pavement. Manual spreading can more finely treat special areas such as shoulders and intersections to improve the overall performance of the pavement.

Modified material bitumen stripper, if the definition is simple, is an bitumen stripper. If described in detail, modified materials such as rubber powder or other fillers are added to the bitumen stripper, or an bitumen stripper is used to Block chemical substances such as photooxygen catalysis. The first is to change the chemical composition of the bitumen stripper, and the second is to use modified materials to equip the stripper with a certain spatial network structure, thereby improving its performance. Modified bitumen strippers mainly include vulcanized rubber and thermoplastic polyurethane elastomer modified bitumen strippers, plastic and anti-corrosion coating modified bitumen strippers and polymer modified bitumen strippers.

With the rapid development of our country’s social development and the continuous development of economic and information technology, modern highway construction is also developing rapidly, and the requirements for ground structural materials are becoming higher and higher, and Asphalt concrete bonding raw materials are inseparable from modified asphalt equipment. So besides these influencing factors, what other reasons does the company have that people don’t understand? Let’s analyze it together.
There are some asphalt concrete equipment on the market, because they have not solved the problem of asphalt clogging before grinding, there are not enough preparation equipment and grinding equipment, the structure is unscientific, and the entire grinding process cannot achieve a certain particle size, resulting in modification. The product productivity of asphalt equipment is low and the product quality is unstable. It requires continuous grinding for a long time, creating problems. This will not only greatly increase energy consumption, increase costs, make product quality unstable, and affect the speed of highway construction.

The fine surface is made of stone with a single particle size, which has high wear resistance and anti-slip properties. The construction of the fine surface adopts mechanized construction, which requires less manual labor and has the characteristics of fast construction speed, anti-skid and noise reduction.
The special bonding material for fine surfaces produced by Sinoroader Group has the characteristics of good bonding performance and good durability. The specific construction process is roughly as follows:

Bitumen decanter equipment can be placed in a complex system as an independent unit, replacing the existing heat source de-barreling method, or in parallel as a core component of a large set of equipment, or it can work independently to meet the requirements of small-scale construction operations.
The Sinoroader bitumen decanter device is mainly composed of a de-barreling box, a lifting mechanism, a hydraulic thruster and an electrical control system. The box is divided into two chambers, the upper chamber is a barreled bitumen melting chamber, and heating coils are evenly distributed around it. The heating pipe and the bitumen barrel mainly exchange heat in a radiation manner to achieve the purpose of bitumen de-barreling. Several guide rails are the tracks for the bitumen barrel to enter. The lower chamber is mainly to continue heating the bitumen removed from the barrel to make the temperature reach the suction pump temperature (100℃), and then the asphalt pump is pumped into the upper chamber. At the same time, an empty barrel is pushed out at the rear end outlet. There is also an oil tank on the platform at the entrance of the asphalt barrel to prevent the dripping bitumen from flowing out.
The inlet and outlet doors of the device adopt a spring automatic closing mechanism. The door can be automatically closed after the asphalt barrel is pushed in or out to reduce heat loss. A temperature gauge is installed at the asphalt outlet to observe the asphalt outlet temperature. The electrical control system can control the opening and closing of the hydraulic pump and the reversing of the electromagnetic reversing valve to realize the advance and retreat of the hydraulic cylinder. If the heating time is extended, a higher temperature can be obtained. The lifting mechanism adopts a cantilever structure. The bitumen barrel is lifted by an electric hoist, and then moved horizontally to place the bitumen barrel on the guide rail. A temperature gauge is installed at the outlet of the asphalt meltering equipment to observe its outlet temperature.

Improve the reliability of SBS bitumen emulsion plants: Once you have an established maintenance, it will help to identify problems. This will allow the maintenance plan and time to be carried out at your convenience. Regular maintenance will increase the normal operation time of SBS bitumen emulsification equipment, and it can be used when necessary. Low cost of operation: Imagine an SBS bitumen emulsification plant breaks down during a project. With a protective maintenance plan, such things happen less often because you have taken good care of the SBS bitumen emulsification plant.
If the SBS bitumen emulsification plant wants to maintain normal operation, then in the production process. All stages need to be maintained normal, among which the normality of the circuit system is an important aspect to ensure its smooth operation. Imagine that if there is a problem with the circuit during the on-site operation, it may affect the development of the entire project.
For users, of course, they don’t expect this to happen, so if the SBS bitumen emulsification plant is in the work of using the SBS bitumen emulsification equipment, if there is a circuit problem, it is necessary to take appropriate measures to solve it in time. The following article will give a detailed description of this problem, and the following SBS bitumen emulsification plant can be of benefit to everyone.

Asphalt used to pave roads. It can be obtained by regular vacuum distillation of crude oil with appropriate properties, and can also be obtained by shallow oxidation of vacuum residue or propane deasphalting process. It can also be prepared by mixing asphalt of different duction and injection degree

Water is one of the raw materials of the modified asphalt storage tank, and it is distributed in various components of the modified asphalt storage tank equipment. According to the components where water is distributed, the anti-cold measures are explained one by one. The water tank of the modified asphalt storage tank, the water inside the water tank is released through the filter valve. Some instruments of the modified asphalt storage tank do not have a filter valve to save the cost of the equipment. The modified asphalt storage tank can only be drained by loosening the flange bolts at the bottom. The water pump of the modified asphalt storage tank mentioned here includes a hot water pump and a circulating water pump. This type of water pump for the modified asphalt storage tank generally uses a pipeline centrifugal pump. There is a sewage outlet at the bottom of the pipeline centrifugal pump. The modified asphalt storage tank pays attention to the sewage treatment of the sewage outlet at the bottom of the pump. The modified asphalt storage tank emulsion tank generally uses a cone bottom. However, in order to better process the modified asphalt storage tank coefficient, the inlet and outlet are usually not placed at the bottom of the modified asphalt storage tank. Emulsion (mostly water) will remain at the bottom of the tank, and this part of the residual liquid in the modified asphalt storage tank must be discharged through the filter valve at the bottom. Emulsion pump for modified asphalt storage tank There are basically two types of emulsion pumps for modified asphalt storage tank equipment on the market, gear pumps or centrifugal water pumps. Gear pumps can only discharge the liquid inside the pump through the connection flange of the pipeline. The centrifugal water pump for modified asphalt storage tanks uses its own sewage outlet for sewage treatment. The first four items of modified asphalt storage tanks with basic knowledge are basically discharged, and the modified asphalt storage tanks will focus on the latter types. Modified asphalt storage tank colloid mill There will also be residual emulsion or water inside the modified asphalt storage tank colloid mill. The gap between the stator and rotor of the colloid mill is within 1mm. If there is a little residual water in the modified asphalt storage tank, it will cause the accident of frozen modified asphalt storage tank. The residue in the colloid mill can be treated by loosening the connection bolts of the finished product pipeline.

Before use, please check whether the position of each valve is accurate and make preparations before work. After starting the motor of the asphalt spreading truck, check the four thermal oil valves and air pressure gauge. After everything is normal, start the engine and the power take-off starts to work. Try running the asphalt pump and cycle for 5 minutes. If the pump head shell is hot to your hands, slowly close the thermal oil pump valve. If the heating is insufficient, the pump will not rotate or make noise. You need to open the valve and continue to heat the asphalt pump until it can operate normally.

All kinds of base layers have the problem of strength formation and growth (Emerson). The strength is gradually generated during the curing process, and the internal structure will become more and more dense. The test shows that when the semi-rigid base layer is sprayed with penetration oil before the cement (material: powdered water-hardening inorganic cementitious material) has not yet hardened, the penetration depth is deep; with the increase of age and strength, the penetration effect of the penetration oil is getting worse and worse.
At the same time, timely spreading of penetration oil has a good retention effect on the moisture in the base layer, preventing the evaporation of moisture, ensuring the formation of the strength of the base layer, and the surface of the base layer is not easy to loosen. The penetration oil also protects the semi-rigid base layer from cracking due to exposure to the sun. Furthermore, since the base layer is no longer covered and watered for curing, the temperature inside the base layer is high, which is conducive to the growth of strength.

The bitumen (composition: asphaltene and resin) drum melting machine adopts a self-heating integrated structure, which integrates the thermal oil boiler used in the old asphalt drum melting machine and the barrel removal equipment itself, reducing the volume of the entire equipment and significantly It reduces equipment investment (actual significance: it is the accumulation of future profits), saves the space occupied by the equipment and the logistics cost of switching sites. The combustion chamber is placed inside the equipment itself, which greatly reduces thermal damage and improves heat utilization.

The requirements for SBS asphalt emulsification equipment are very high. The micro powder machine must have a sufficiently large driving force and can bear the condensation type. Because the temperature requirements of the emulsion SBS asphalt process are relatively high, the emulsified asphalt should be passed through a heat exchanger before feeding to reduce the emulsified asphalt temperature to below 90°C to prevent the emulsified asphalt from breaking due to excessive temperature.
The application scope of SBS modified emulsified asphalt is very wide. According to the nature of the construction, it can be used in new construction, renovation, and reconstruction projects; according to the nature of the project, it can be used in overhaul, equipment overhaul, and maintenance projects. Among them, the actual application projects include micro-surfacing, cold regeneration, cold mixing and cold paving, adhesive layer, permeable oil, slurry seal, gravel permeable layer, fog permeable layer, road moisture-proofing, SBS membrane, ground seam filling, and all other projects that can use emulsified asphalt.
