Various types of modified asphalt equipment meet user needs

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.

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

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:

What key points should be paid attention to when feeding emulsified asphalt equipment? When it comes to emulsified asphalt equipment, I don’t know how much you know about it? What should you pay attention to when adding materials?
The black anti-static tweezers grinding wheel of the emulsified asphalt equipment does not have a heated collet. Before use, you must add the appropriate amount of diesel and let the black anti-static tweezers circulate for 3 to 5 minutes to generate heat (the temperature after operation is 80 ~100 degrees) open the stop valve on the oil delivery pipe to drain the diesel engine in the engine. The temperature of the black anti-static tweezers grinding wheel must be around 80 to 100 degrees before the material can be loaded and put into production. If there is a heated collet, the grinding wheel must be heated before starting, and then the material is loaded and put into production.

Working conditions of asphalt debarreling equipment:
(1) Outdoor temperature: 20°C (average temperature of day and night)
(2) Heat exchange oil: 320 ℃
(3) Loading time is not included (because the personnel equipped in each unit are different, so the loading time is also different)
(4) There is no fluctuation in oil temperature (optimal automatic burner)
(5) The working temperature of the oil furnace is 220-260 ℃
(6) The flow rate of the oil circulation pump is not less than 50m3/h traffic
(7) When the outdoor temperature is lower than 20℃, the output decreases. The lower the temperature, the lower the output, and the higher the temperature, the higher the output.
(8) The greater the deformation of the asphalt barrel, the greater the impact on the output

Technical features of fiber sealing equipment:
1. Zero starting strong injection technology

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.

Is the performance of Sinoroader’s fully automatic emulsified asphalt production equipment stable and unstable? To be honest, whether the performance of a product is stable or not can only be known through practice, right?
Chairman Mao, the great leader of China, once said, “Without practice, there is no right to speak.” Yes, people who have never used it naturally have no right to speak. Now the editor will talk about the fully automatic emulsified asphalt production equipment that I am using!

Each F1 track must be paved with three layers of asphalt, middle and lower, of which the lowest layer is 10 cm coarse asphalt concrete bearing layer, its flatness is less than 8 mm; In the middle is a 4 cm medium grained asphalt concrete bond layer, its flatness is less than 5 mm; The top layer uses 4 cm modified asphalt mixture as the surface wear layer, and the flatness is less than 2 mm.

The paved F1 track cannot have more than 3 points per kilometer of flatness detection, which is much higher than the highway.

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.

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.

Everyone has a side of themselves that they don’t want others to know. As a preventive road maintenance technology, slurry sealing has some shortcomings. do you think so?
Slurry seal is a kind of road protection that uses special equipment to mix emulsified asphalt, water, additives, aggregates, fillers and other ingredients in a certain proportion, and then mixes the slurry mixture onto the original road surface to form a thin layer. Maintenance technology. These are all well known. The editor will not go into details on this.

The container-type emulsified bitumen equipment hot-melts the base cold-mix colored bitumen and disperses it through the equipment into small cold-mix colored bitumen particles in an aqueous solution containing emulsifier to form a liquid cold-mix colored bitumen material.

From the current point of view, road construction machinery has bottomed out and asphalt meltering equipment has risen rapidly. In recent years, highway construction and maintenance departments have a strong awareness of using asphalt mixing equipment, especially in developed coastal areas such as Beijing, Shanghai, Jiangsu, Zhejiang, etc. In addition, these regions have a fast economic growth rate, relatively developed industry, and strong comprehensive economic strength. Therefore, the consumption of asphalt mixing equipments in these regions has always been at the forefront of the country. With the rapid development of highway construction and the increase in demand for asphalt, barreled asphalt has been widely used for its convenient transportation and easy storage. In particular, most of the high-performance imported asphalt used in high-grade highways is in barrel form, which requires an asphalt meltering equipment with fast melting speed, clean de-barreling, and can prevent asphalt aging. my country’s highway construction has achieved remarkable results, among which mechanized production has contributed greatly. Different types of asphalt mixers and bitumen meltering equipment are selected for the characteristics of large highway pavement construction and tight construction period. With the rapid development of my country’s economy, the further extension of expressways, and the large-scale development of western construction, the central and western regions have become new investment hotspots. While paying attention to the market in the developed eastern regions, domestic road construction machinery manufacturers have also increased their efforts to develop the central and western markets, creating new highlights for the domestic asphalt mixing plants consumer market. In summary, my country’s asphalt mixing plant sales market has begun to move westward with the westward movement of investment hotspots. As the market center of gravity gradually shifts westward, the market in the western region is gradually heating up. The self-heating integrated structure, hot air barrel melting and bitumen barrel flipping technology in the asphalt barrel removal equipment are our company’s self-heating integrated structure. The thermal oil furnace used in the old equipment is perfectly integrated with the asphalt barrel removal equipment body, which reduces the volume of the entire set of equipment, greatly reduces equipment investment, saves equipment space and transfer transportation costs.

1 Common diseases of asphalt pavement
There are nine phenomena of early damage to asphalt pavement: rutting, cracks, and potholes. These diseases are the most common and serious, and are one of the common quality problems of highway projects.
1.1 Rutting
Rutting refers to the longitudinal strip grooves on the road surface along the wheel tracks, with a depth of more than 1.5cm. Rutting is a strip groove formed by the accumulation of permanent deformation of the road surface under the repeated action of vehicle load. Rutting reduces the smoothness of the road surface. When the rutting reaches a certain depth, due to the accumulation of water in the rutting, it is easy for cars to slide and cause traffic accidents. The main reasons for rutting are unreasonable design and serious overloading of vehicles.
1.2 Cracks
There are three main forms of cracks: longitudinal cracks, transverse cracks and mesh cracks. When cracks occur in asphalt pavement, water seepage occurs, which harms the surface layer and base layer.
1.3 Potholes
Potholes are common early diseases of asphalt pavement, which refer to the road surface being damaged into potholes with a depth of more than 2cm and an area of ??more than 0.04㎡. The main reason for the formation of potholes is that the oil used in vehicle repair or motor vehicles seeps into the road surface, polluting the asphalt mixture and causing it to loosen. The pits are gradually formed by driving and rolling.

The whole set of procedures is modularized, and customers can freely match and use according to their needs. The application of each part of the equipment is as follows: Sewage treatment system: Mechanically filter and adsorb the general drinking water to react with epoxy resin to convert the strong drinking water into pure softened water, reduce the water holding capacity, and improve the emulsion effect of asphalt or asphalt concrete.

Synchronous gravel sealing technology refers to the use of special synchronous gravel sealing truck equipment to lay and roll prepared gravel, asphalt and other materials to build a single layer of asphalt gravel wearing layer, which is important for highway pavement. protection of. From the perspective of characteristics, it is simple and easy to implement. It has obvious effects on the prevention of highway diseases, problem solving, later maintenance, and improvement of grade protection. It can also well extend the service life of highways.

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.

To ensure good operation of asphalt melting equipment and extend its service life, regular maintenance and repairs are required. The following are specific maintenance and repair steps:
First, various parts of the equipment, including heating elements, pipes, valves, etc., need to be inspected regularly to make sure they are not worn or damaged. If any problems are found, they should be repaired or replaced immediately.

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.

The hydraulic bitumen decanter equipment produced by our company uses thermal oil as the heat carrier and has its own burner for heating. The thermal oil heats, melts, debarks and dehydrates the asphalt through the heating coil. This device can ensure that the asphalt does not age, and has the advantages of high thermal efficiency, fast barrel loading/unloading speed, improved labor intensity, and reduced environmental pollution.

I believe everyone is familiar with the relevant knowledge about modified bitumen equipment. As users continue to increase its application, we have also talked about it a lot in the above articles and learned that it is mainly engaged in the production of modified bitumen. Production, in order to further enhance users’ understanding of it, professionals summarize its relevant characteristics as follows:

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.

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.
