Slurry seal spreader boxes

Preparation items for micro-surfacing slurry sealing: materials, construction machinery (micro-surfacing paver) and other auxiliary equipment.
The micro-surface slurry seal requires emulsified asphalt and stone that meet the standards. The metering system of the micro-surfacing paver needs to be calibrated before construction. The production of emulsified asphalt requires asphalt heating tanks, emulsified asphalt production equipment (capable of producing asphalt content greater than or equal to 60%), and emulsified asphalt finished product tanks. In terms of stone, mineral screening machines, loaders, forklifts, etc. are needed to screen out oversized stones.
The tests required include emulsification test, screening test, mixing test and the equipment and technical personnel required to do these tests.

The new slurry sealing truck developed by Sinoroader Company continues the design concept of the original spreader truck.

The base layer of asphalt pavement is divided into semi-rigid and rigid. Since the base layer and the surface layer are materials of different properties, good bonding and continuity between the two are the key requirements for this type of pavement. In addition, when the asphalt surface layer seeps water, most of the water will be concentrated at the joint between the surface layer and the base layer, causing damage such as slurry, looseness, and potholes to the asphalt pavement. Therefore, adding a lower seal layer on top of a semi-rigid or rigid base layer will play a vital role in enhancing the strength, stability and waterproofing capabilities of the pavement structural layer. The more commonly used one is to use asphalt gravel synchronous sealing technology.
So let’s take a look at how the construction of the asphalt gravel synchronous sealing truck is carried out:

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 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.

Bitumen emulsion equipment is widely used in new technologies and new processes for preventive maintenance. Bitumen emulsion plant is an emulsion at room temperature formed by dispersing bitumen into the water phase. It is a new material that is made of natural materials. It is different from traditional Compared with hot bitumen, it saves more than 50% of energy, saves 10%-20% of bitumen, and causes less pollution.

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.

In the cold winter, the following points should be noted when using bitumen melter equipment:

1. Keep warm: The bitumen melter equipment needs to be operated indoors or in a place with sunshade facilities, and ensure that the temperature of the bitumen melter and the surrounding environment is kept within an appropriate range.
2. Check the bitumen melting equipment: Before use, the bitumen melter should be checked, including whether the circuit, liquid circuit and other parts of the equipment are working properly, and whether the equipment has leakage, water leakage and other conditions.
3. Pay attention to safety: During operation, protective bitumen melter equipment should be worn to avoid direct contact with hot bitumen. At the same time, avoid overloading the bitumen melter to prevent equipment damage and safety accidents.
4. Control speed: Reasonably control the working speed of the bitumen melting equipment according to weather conditions and road conditions to avoid overheating of the equipment, which may cause the bitumen to flow too quickly or burn.
5. Storage conditions: When not in use, place the equipment in a dry, ventilated and moderately warm place, and ensure that the residue in the equipment is completely cleaned.

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.

Maintenance points of asphalt spreading trucks in different working hours
per month (or every 200 hours worked)；
​Per year (or every 500 hours worked)；
Every two years (or every 1,000 hours worked)；

In addition to being used according to regulations, modified bitumen equipment should also be maintained regularly in order to effectively extend the service life of modified bitumen equipment. The delivery pump of modified bitumen equipment, as well as its motor and reducer, need to be maintained in accordance with the specifications of the instructions. If the modified bitumen equipment is parked for a long time, the liquid in the tank and pipeline needs to be drained, and each moving component also needs to be filled with grease. The dust in the control box of the modified bitumen equipment needs to be cleaned once every six months. A dust blower can be used to remove dust to prevent dust from entering the machine and damaging parts. The micro powder machine needs to add unsalted butter once for every 100 tons of emulsified bitumen produced.

Asphalt spreader is an irreplaceable tool for highway maintenance. Asphalt spreader is an irreplaceable tool for highway maintenance. Highway maintenance is divided into four categories according to the nature of the project, scale, and technical complexity: minor repair, medium repair, major repair, and improvement. Specific classification:
(1) Minor repair and maintenance project: preventive maintenance and repair of slightly damaged parts of the highway and all its engineering facilities to keep them in good condition. It is usually planned and carried out daily by the maintenance team within the annual minor repair and maintenance quota funds on a monthly (ten-day) basis.
(2) Medium repair project: regular repair and reinforcement of general wear and tear and local damage of highway engineering facilities to restore them to their original state. It is usually planned and implemented by grassroots road maintenance agencies on an annual (seasonal) basis.
(3) Major repair project: periodic comprehensive repair of major damage to highway facilities to fully restore them to the original design standards, or local improvements and individual additions within the original technical level to gradually improve the highway’s traffic capacity. It is usually organized and implemented by grassroots road maintenance agencies or with the help of their superior agencies according to the approved annual project budget.
(4) Improvement projects are large projects that improve the technical level of roads and their engineering facilities in stages and sections due to their inability to meet traffic volume and load requirements, or significantly improve traffic capacity through improvements. It is usually organized and implemented or completed through bidding by regional road maintenance agencies or provincial road maintenance agencies according to the approved plan and design budget.

Slurry sealing layer truck is a thin layer formed by using mechanical equipment to mix properly graded emulsified asphalt, coarse and fine aggregate, water, fillers (cement, lime, fly ash, stone powder, etc.) and additives into slurry mixture according to the design ratio and spread on the original road surface.

1. When operating an asphalt spreading truck, first check whether the machinery, spreading devices, protective and fire prevention equipment are complete and effective.
2. It is strictly prohibited to use non-specified fuel as the fuel for the heating system. The fuel is not allowed to overflow outside the tank. Generally, the oil level should be 20-30cm lower than the upper end of the overflow pipe.

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.

Bitumen melter equipment plays an important role in highway construction, but traditional heating methods have problems such as high energy consumption and low efficiency. This article introduces a new type of bitumen melting plant, which uses electric heating technology and has the advantages of energy saving, environmental protection and environmental protection. The working principle of this equipment is to heat the bitumen through the heat generated by the resistance wire, and then automatically adjust the temperature and flow rate through the control system to achieve the best melting effect.

Asphalt emulsifier is an emulsifier that belongs to the category of surfactants and is a raw material for the production of emulsified asphalt.
Emulsifiers are divided into: synthetic emulsifiers, natural emulsifiers, inorganic powder emulsifiers, etc. Currently, synthetic emulsifiers are widely used. Asphalt emulsifier is a type of chemical organically synthesized surfactant.

From three aspects, emulsion bitumen equipment has good economic performance:
First, energy saving. The kerosene or gasoline content in diluted asphalt can reach 50%, while the emulsion bitumen plant only contains 0-2%. This is a valuable saving behavior in the production and utilization of white fuel. By simply increasing the viscosity standard of asphalt by adding light oil solvent, asphalt can be poured and spread, and it is hoped that the light oil after use can evaporate into the atmosphere.
Second, versatility. There are many application methods for emulsion bitumen plants, and the appropriate method needs to be selected when applying it. The same emulsion can be used for large-scale sealing and can be used for small-scale pit repair work. Because they can be stored in tanks for a long time, they are very easy to use when applied in remote areas.
Third, it is easy to use. The professional spreading of emulsions requires professional equipment, such as spreaders. Small-area emulsion applications can be directly poured and spread by hand, such as small-area pit repair work, crack fillers, etc. Small quantities of cold mixes only require basic equipment.

Asphalt mixing plants bring a lot of convenience. You should understand what asphalt is. Asphalt is a very viscous liquid with a black surface that dissolves carbon disulfide. They generally exist as asphalt and smoke tar. Asphalt appeared early in social life.

Asphalt melting equipment is one of the indispensable equipment in modern road construction. Its main function is to heat a large amount of cold hard asphalt to a suitable working temperature at the construction site. Advanced asphalt melting equipments can greatly improve construction efficiency, reduce human resources and time costs, and ensure pavement quality at the same time.
First of all, reliable asphalt melter equipment can shorten heating time and work efficiency and avoid wasting energy. Secondly, the equipment is easy to operate and can reduce the incidence of on-site safety accidents. In addition, this equipment has an automatic control and monitoring system that can adjust the working status and parameters at any time to meet different construction needs and environmental conditions.

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:

The heating principle of asphalt decanter equipment is to heat, melt and decanter the asphalt through the heating plate. It is mainly composed of de-barreling box, lifting system, propeller and electrical control system.
The box of asphalt decanter plant is divided into upper and lower chambers. The upper chamber is the asphalt melting chamber, which is densely covered with heat transfer oil heating coils or hot air heating pipes. The asphalt is melted and removed from the barrel by heat. The hoisting hook is installed on the gantry, and a barrel grabber is hung. The asphalt barrel is lifted by the electric winch, and then the asphalt barrel is placed on the guide rail by horizontal movement. Then the propeller pushes the barrel into the upper chamber through two guide rails, and an empty barrel is pushed out at the rear end outlet.
An anti-drip oil tank is provided at the entrance of the asphalt barrel. The asphalt enters the lower chamber of the box and is continuously heated to a temperature of about 100 to be transported, and then pumped into the asphalt tank by the asphalt pump. The lower chamber can also be used as an asphalt heating tank.
The asphalt decanter plant has the characteristics of not being restricted by the construction environment, strong adaptability and extremely low failure rate. If large production is required, multiple units can be assembled.

Synchronous sealing trucks play an important role in road maintenance. Daily maintenance of synchronous sealing trucks is an important part of ensuring the good operation of the equipment and extending its service life. Here are some common maintenance measures:

The engine is the source of power for the vehicle. If the synchronous sealing vehicle wants to perform normal construction operations, it must ensure that the engine is in good condition. Routine maintenance is an important means to effectively prevent engine failure. How to maintain it is determined by Xinxiang Junhua Special Vehicle Vehicles Co., Ltd. will take everyone to understand.

Asphalt spreading trucks are used to spread the permeable oil layer, waterproof layer and bonding layer of the bottom layer of asphalt pavement on high-grade highways. It can also be used in the construction of county and township-level highway asphalt roads that implement layered paving technology. It consists of a car chassis, an asphalt tank, an asphalt pumping and spraying system, a thermal oil heating system, a hydraulic system, a combustion system, a control system, a pneumatic system, and an operating platform.

There are many ways to heat bitumen, including using fire source heating, electric heating, steam heating, hot water heating and indirect heating. Fire source heating generates heat by burning fuel to heat the bitumen to a molten state. Electric heating converts electrical energy into thermal energy through electric heating elements to heat the bitumen to a molten state. Steam heating transfers heat to bitumen through steam, heating the bitumen to a molten state. Hot water heating transfers heat to the bitumen through hot water, heating the bitumen to a molten state. Indirect heating transfers heat to the heating medium, which then transfers the heat to the bitumen to heat the bitumen to a molten state.

Synchronized gravel sealing is a process technology for treating cracks in asphalt pavement, and it is currently a road construction and pavement maintenance technology with low energy consumption and high cost performance. Do you know what its six technical features are? If you don’t know, just follow the editor of Sinoroader and take a look.

In the cold winter, you need to pay attention to the following points when using asphalt melting equipment:
1. Protection from cold and warmth: The equipment needs to be operated indoors or in a place with shading facilities, and ensure that the temperature of the equipment and the surrounding environment is maintained within an appropriate range.
2. Check the equipment: Before use, the equipment should be checked, including whether the circuits, fluid circuits and other parts of the equipment are working normally, and whether there are any leaks of electricity or water in the equipment.
3. Pay attention to safety: During operation, you should wear protective equipment and avoid direct contact with hot asphalt. At the same time, it is necessary to avoid equipment overload operation and prevent equipment damage and safety accidents.
4. Control speed: Reasonably control the working speed of the equipment according to weather conditions and road conditions to avoid overheating of the equipment, causing asphalt to flow too quickly or burn.
5. Storage conditions: When not in use, place the device in a dry, ventilated place with moderate temperature, and ensure that any residue in the device is completely removed.

There are certain standards for the composition and mix ratio of micro-surfacing, and a wide range of materials are used, including polymer-modified emulsified asphalt, various aggregates, cement, water, additives, etc. Raw material quality has a significant impact on microsurfacing performance, so understanding the performance of each component and the key factors that influence its performance is critical to ensuring the quality of your microsurfacing mix.

Emulsified modified asphalt equipment is classified according to the production process and can be divided into three types: intermittent emulsified modified asphalt equipment, semi-continuous emulsified modified asphalt equipment, and continuous emulsified modified asphalt equipment. During the production of emulsified modified asphalt equipment, demulsifier, acid, water, and latex modified materials are blended in a soap mixing tank, and then pumped into the asphalt into the colloid mill. After a can of soap is used up, the soap is redispensed, and then the production of the next can is completed.
The emulsified modified asphalt equipment mentioned here includes hot water pumps and circulation pumps. This type of centrifugal water pump generally uses a pipeline centrifugal pump. There is a sewage outlet at the bottom of the pipeline centrifugal pump. Pay attention to the sewage outlet at the bottom of the emulsified modified asphalt equipment pump. The water in the water tank is released through the filter valve. Some emulsified modified asphalt equipment does not have a filter valve to save equipment costs, so it can only be emptied by loosening the flange bolts at the bottom. There are basically two methods of moisturizing emulsion pumps for emulsified modified asphalt equipment on the market, gear oil pumps or centrifugal water pumps. The gear oil pump can only drain the liquid in the pump through the connecting flange of the pipeline. The centrifugal water pump carries out sewage treatment through its own sewage outlet.
When used in the production of emulsified modified asphalt equipment, depending on the modified material technology, the latex pipeline can be connected in front of the colloid mill or behind the colloid mill, or there may be no latex pipeline and it must be made manually. Add the required amount of latex into the soap jar.
