slurry sealing truck developed by Sinoroader

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.

Asphalt mixture mixing equipment is a factory-style complete set of equipment that mixes dry and heated aggregates of different particle sizes, fillers and asphalt according to the designed mix ratio at a specified temperature into a uniform mixture. It is widely used in high-grade highways and urban roads. , airports, docks, parking lots and other engineering construction. It is a key equipment for asphalt pavement construction, and its performance directly affects the quality of asphalt pavement.
Generally, there are two types of asphalt concrete mixing equipment: intermittent type and continuous type. The continuous process flow is simple and the equipment is simplified. As for the intermittent forced mixing equipment, due to the secondary screening of aggregates, various components are measured in batches, and forced stirring and mixing can reliably ensure gradation, and the measurement of powder and asphalt can also achieve very high accuracy; so the mixing equipment The asphalt mixture produced is of high quality and can meet various construction requirements.

Whether it is the application of modified asphalt equipment or the application of other equipment, if you want to extend its service life, you need to do daily maintenance work. In order to better help everyone, we have modified asphalt The maintenance methods that can be adopted when using the equipment are introduced as follows:

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.

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.

The modified asphalt equipment estimates the quality and uniformity of various raw materials from the material pile and conveyor at any time. The modified asphalt equipment checks the soil and oversized gravel, and checks whether there is any leakage in the cold hopper. Estimate whether the mixed material is mixed evenly, whether there is white material, whether the oil-stone ratio is reasonable, and check the concrete segregation of the asphalt mixture and the mixed material.
The modified asphalt equipment checks the control parameters of various basic parameters of the mixing device in the control room, the display values ??of the control screen, and the modified asphalt equipment checks whether the data statistics and display values ??of the computer and printout are consistent. Test the raw material heating temperature and the mixed material entry temperature of the modified asphalt equipment.

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.

With the development of science and technology, the emergence of emulsified asphalt tanks has brought great convenience to our work, and is widely used in every site. So what issues need to be paid attention to when filling emulsified asphalt tanks? Below, the editor will introduce to you the relevant knowledge structure diagram, hoping to be of some help to you.

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.

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:

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!

Asphalt mixing stations and equipment must implement secondary leakage protection measures. They can only be used after being plugged in and operated through the circuit breaker before use. During the trial operation, it is necessary to verify that the rotational speed of the mixing drum will be inappropriate.

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 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.

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.

Friends who are ready to get started have a surprise today. The editor will give you a brief introduction on how to produce emulsified asphalt.

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.

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.

Everyone must be familiar with slurry sealing and micro-surfacing. But do you know their 7 construction steps?
Slurry sealing and micro-surfacing were both early preventative highway protection technologies. Its function is to ensure the smooth use and extended life of the highway. The construction steps are as follows:

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.

The viscosity of the drum bitumen decanter equipment decreases as the temperature increases during the production process. Its output viscosity is about twice as high as every 12°C increase. During production, the base bitumen decanter equipment must first be heated to a liquid state and then emulsified. In order to better integrate the emulsification ability of colloid milling, the viscosity of base bitumen decanter is generally controlled to be about 200 cst. The lower the temperature, the higher the viscosity, which increases the pressure on the bitumen decanter pump and colloid milling, making emulsification impossible: However, on the other hand, in order to prevent the bitumen decanter equipment from weaning when the moisture of the finished product evaporates, it is impossible to heat the base asphalt barrel removal temperature too high, and generally use a colloid grinding inlet and outlet system. The finished product temperature should be below 85°C.

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.

Asphalt spreader vehicle is an intelligent and automated high-tech product that specializes in spreading emulsified asphalt, diluted asphalt, hot asphalt, high-viscosity modified asphalt, etc.
Asphalt spreader is used for spreading the penetration oil, waterproof layer, and bonding layer of the bottom layer of the asphalt pavement of high-grade highways. The spreader consists of a car chassis, an asphalt tank, an asphalt pumping and spraying system, a thermal oil heating system, a hydraulic system, an ignition system, a control system, a pneumatic system, and an operating platform.
Asphalt spreader is cumbersome to operate. On the basis of absorbing various technologies of similar products at home and abroad, it increases the quality technology content of construction and the humanized design of outstanding improvement of construction conditions and construction environment. Its reasonable and reliable design ensures the uniformity of asphalt spreading, the computer control is stable and reliable, and the technical performance of the whole vehicle has reached an advanced level.

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.

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