Regarding the basic knowledge of modified bitumen plant, I believe that many consumers have already had a basic understanding of it. Because of the continuous development of various fields today, various facilities including modified bitumen plants have been well developed and applied, and modified bitumen plant has gradually been recognized by customers.
The direct quick heating portable equipment in the modified bitumen equipment not only has a faster heating speed, saves fuel, and is pollution-free, but also convenient and easy to operate. The automatic heating system completely eliminates the trouble of baking or cleaning bitumen and pipelines.

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.

During the use of emulsified bitumen equipments, if maintenance is not paid attention to, the cycle will be short, and problems will often occur during use. Only by doing a good job of maintenance can the operation efficiency of the equipment be improved. For example, during maintenance, the following points must be grasped.
It is necessary to regularly check the wear condition of the internal structural components of the mechanical equipment, such as the core feed pipe, the rough jaw plate on the impeller, the cone cap, the wear level of the jaw plate, the rain shield on the circle, and the wear condition. If the wear is more serious, it is necessary to replace or repair it in time. When replacing, it is also necessary to pay attention to the model and specifications, and replace it according to the original components as a reference.

Bitumen emulsifier is a surfactant. A surfactant is a compound that reduces the surface tension between two liquids, a gas and a liquid, or a solid and a liquid. Surfactants are mainly used in: detergents, detergents, fabric softeners, wetting agents, emulsifiers, foaming agents, dispersants, adhesives, etc.

Asphalt melting equipment is an important road construction tool used to heat asphalt to the appropriate temperature for construction. It can provide reliable solutions and make road construction more convenient. The working principle of this equipment is to heat the asphalt to the appropriate temperature through a heater, and then transport the hot asphalt to the construction site through a conveying system.

As we all know, emulsified bitumen is a single-component black viscous liquid that can combine the roadbed and the pavement to improve the performance and service life of the road. So what problems should be paid attention to when using emulsified bitumen? Let’s follow the editor of Sinoroader Group, an emulsified bitumen manufacturer, to learn about it.

As a manufacturer with many years of experience in emulsified bitumen construction, Sinoroader Group believes that everyone needs to pay attention to the following 2 points when using it:

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.

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.

Microsurfacing is a thin layer of overlay placed on old asphalt pavement and is a type of preventive maintenance process. The purpose of microsurfacing is road maintenance. After micro-surface paving, it can repair cracks in the original road surface, waterproof and beautify the road surface.
The construction method of micro surfacing is: using a micro surfacing paver to evenly spread modified emulsified asphalt, a certain grade of mineral materials, water and other additives on the road surface in a certain proportion.

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.

Abstract: 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 equipment can greatly improve construction efficiency, reduce human resources and time costs, and ensure pavement quality at the same time.

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.

Stainless steel bitumen melters use bitumen concrete micro-powder machines. Its blade strength is high, the angular velocity of the moving disc is high, and the gap can be adjusted to 0.15mm. Stainless steel bitumen melters are suitable for the production and processing of various polymer bitumen concrete, such as SBS, PE, EVA, etc.
Stainless steel bitumen melters use independently developed special batching tanks, stainless steel bitumen melter force stirring devices, liquid level meter overflow prevention equipment, granular material dosage and equipment, liquid additive automatic addition equipment and other production key points. It ensures the full-position process guarantee for the stainless steel bitumen melter of the bitumen concrete production line. The stainless steel bitumen melter processing stainless steel bitumen melter rate is significantly increased, and the quality of stainless steel bitumen melters is greatly improved.

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.

Here is an introduction to the knowledge on construction quality control of modified rubber asphalt equipment. Let’s introduce this knowledge from three aspects. The details are as follows: The viscosity of the modified asphalt mixture of modified rubber asphalt equipment is relatively high, and the construction temperature of each process is The construction temperature requirements are higher than those of ordinary asphalt mixtures.

In our daily life, we can often see emulsified asphalt equipment. Its appearance has brought us great convenience. So what is the difference between its modification process? Below, the editor will give you a brief introduction to the relevant knowledge points.
1. Emulsified asphalt equipment first emulsifies and then modifies: This is a relatively simple way to make modified emulsified asphalt. The production process is to grind hot asphalt and emulsifier soap together through a colloid mill to make ordinary emulsified asphalt, and then add latex-like modifiers to the emulsified asphalt through mechanical stirring to make modified emulsified asphalt. The characteristic of this method is that it does not require high equipment.

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 heat transfer 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.

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.

Modified bitumen equipment uses modified bitumen colloid mill. Its blade has high hardness, high linear speed of the moving disk, and the gap can be adjusted to 0.15mm. It is suitable for processing various polymer-modified bitumens, such as SBS, PE, EVA, etc.

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.

Emulsified modified asphalt equipment includes sewage treatment, water storage tank, water metering and verification temperature control system, asphalt storage tank, asphalt external temperature control system, hot water pump soap seasoning system, soap storage tank, soap mixing pump, soap external temperature control system and metering and verification system, filter, hot asphalt mixing pump and metering and verification system, pipeline black anti-static tweezers, emulsified asphalt cooling system and retrieval equipment, product tank and electrical control system.
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.

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.

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.

According to the configuration, layout and controllability of bitumen melting equipment, bitumen melting plant can be divided into three types: mobile, transportable and portable. What should be paid attention to in the production of bitumen melter equipment of different sizes? Let’s learn about it below!
Bitumen melting plant is to fix the demulsifier mixing equipment, black anti-static tweezers, asphalt pump, automatic control system, etc. on a special support chassis. Because the bitumen melter equipment can directly change the production site, it is suitable for the production of emulsion bitumen in construction sites with decentralized projects, small usage and frequent movement.
The main components of the bitumen melting equipments are installed in one or two 60 standard containers. The bitumen melting plant is loaded and transported separately to complete the relocation of the construction site. With the help of asphalt melting equipments hoisting equipment, it is quickly installed and put into operation. Such bitumen melter plant has large, medium and small different configurations, which can meet different project requirements.

The bitumen decanter equipment is mainly composed of barrel removal shell (BOX), hoisting mechanism, hydraulic booster and electrical control system. The shell is divided into two chambers, the left and right chambers. The upper chamber is a chamber for melting a large barrel of bitumen (definition: the transformation process of a substance from solid to liquid). There are heating coils evenly distributed around it.

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.

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.

There is a wide variety of asphalt melting equipment on the market, including different brands and models. The prices of these devices vary widely, depending mainly on factors such as their features, performance, and specifications.
Asphalt melter equipment produced by some large brands such as Sinoroader usually has higher quality and reliability, so the price is relatively higher. However, they also offer longer service life and better maintenance support.

The slurry seal truck is mainly used for preventive maintenance of municipal pavement. It can improve the quality of the seal, effectively improve the integrity and crack resistance of the seal, extend the service life, and the construction process is simple without adding too many construction links. It is a kind of road maintenance equipment that has become quite popular in recent years.
