A brief discussion on the new market trend of bitumen meltering equipment

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.

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.

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.

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.

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.

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:

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.

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 spreading amount is accurate, and three overlapping asphalt sprayings can be achieved with good uniformity;
● Intelligent control of spreading amount, real-time monitoring of spreading amount and vehicle speed, closed-loop control;
● Full computer touch screen operation, equipped with video monitoring system, the entire work process can be observed at any time;
● Reliable performance, durability and easy operation;

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.

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.

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.

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 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.

What is an bitumen colloid mill used for? Everyone knows about colloid mill, but what about bitumen colloid mill?
Bitumen colloid mill is a high-tech multifunctional crushing and grinding equipment. The motor drives the rotating teeth and fixed teeth to rotate at high speed, generating a sharp speed gradient, which causes the boring to be strongly sheared, rubbed and turbulent, and finally achieves emulsification and dispersion. and homogenizing effect equipment.

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.

Asphalt melting equipment is a mechanical equipment specially used to heat and melt asphalt. Our company’s products have been widely recognized and applied in the market.
Our main production process is: transporting the high-temperature oil and gas generated after high-temperature cracking of raw materials (such as petroleum) in the combustion chamber to high-speed rotating heat-conducting oil tankers for heat transfer, melting, cooling and other processes, and finally obtaining the required finished materials or Semi-finished materials. The advantage is that it can make the best use of raw materials and reduce energy consumption; at the same time, it can also customize products of different specifications according to different needs to meet the different requirements of customers. In addition, we provide after-sales service and technical support to protect the interests and safety of our customers.

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.

Preventive pavement maintenance is a periodic mandatory maintenance measure, which is taken to restore the pavement surface service function when the pavement structure strength is sufficient and only the surface function is attenuated. New preventive maintenance technologies such as super-viscous fiber-added low-noise micro-surfacing and synchronous gravel seal have been widely used on the main lines of national highways, and the construction effect has been widely praised by customers.
Super-viscous fiber-added low-noise micro-surfacing starts with the gradation of micro-surfacing and the main material modified emulsified asphalt. By reducing the structural depth of the micro-surfacing and changing the distribution state of the coarse and fine materials on the surface of the micro-surfacing, the driving noise is reduced, while ensuring its anti-skid performance, effectively improving its adhesion, waterproofness, durability and crack resistance, and can solve the defects of easy detachment, excessive noise and reflective cracks of ordinary micro-surfacing.

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.

We need to prepare a lot of work when using modified asphalt equipment. What kind of work do we need to prepare? Next, let me briefly introduce the relevant knowledge points.
1. Heat transfer oil heats and insulates the modified asphalt equipment and nozzle. After spraying, the asphalt pump and nozzle do not need to be cleaned with diesel. Use high-pressure air to press the asphalt in the pipeline and spray pipe back to the tank, and then blow the nozzle; use heat transfer oil to keep warm, so that the pipeline and nozzle are smooth and unobstructed. 2. Various asphalts can be spread: high-viscosity asphalt, hot asphalt, emulsified asphalt, etc.; the spreading width can be freely adjusted, each nozzle can be controlled separately, and the maximum spraying width is up to 6m. Flexible handheld spray guns can be used to spray asphalt on corners. 3. Excellent thermal insulation performance, average cooling ≤1-2℃/h. 4. Convenient loading and unloading function. In addition to filling asphalt from the asphalt tank port, hot asphalt can be sucked out by itself, and external asphalt can also be pumped and transferred. 5. The modified asphalt equipment is evenly spread, and the nozzle design can be used for triple overlapping spraying.
The above are the relevant knowledge points of modified asphalt equipment. I hope the above content can be helpful to everyone. Thank you for your viewing and support. More information will be sorted out for you later. Please pay attention to our website updates.

What is the overall operation process of bitumen (composition: asphaltene and resin) drum melting 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.

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.

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.
