[1] Common diseases of asphalt pavement
There are nine types of early damage to asphalt pavement: ruts, cracks, and potholes. These diseases are most common and serious, and are one of the common quality problems of highway projects.
1.1 Rut
Ruts refer to the longitudinal belt-shaped grooves produced along the wheel tracks on the road surface, with a depth of more than 1.5cm. Rutting is a band-shaped groove formed by the accumulation of permanent deformation in the road surface under repeated driving loads. Rutting reduces the smoothness of the road surface. When the ruts reach a certain depth, due to water accumulation in the ruts, cars are most likely to slide and cause traffic accidents. Rutting is mainly caused by unreasonable design and serious overloading of vehicles.

The emulsified asphalt equipment is an "internally heated local rapid asphalt storage heater device". The series is currently the most advanced asphalt equipment in China that integrates fast heating, energy saving and environmental protection. Among the products, it is a direct heating portable equipment. The product not only has a fast heating speed , save fuel, and do not pollute the environment. It is easy to operate. The automatic preheating system eliminates the trouble of baking or cleaning asphalt and pipelines. The automatic cycle program allows the asphalt to automatically enter the heater, dust collector, induced draft fan, asphalt pump, and asphalt as needed. It consists of temperature display, water level display, steam generator, pipeline and asphalt pump preheating system, pressure relief system, steam combustion system, tank cleaning system, oil unloading and tank device, etc., all of which are installed on (inside) the tank to form a Compact one-piece structure.

When using a thermal oil bitumen tank, it should be noted that the longer the bitumen is stored in the thermal oil bitumen tank, the more sediment will be produced by oxidation, and the more serious the impact will be on the quality of the bitumen. Therefore, when using a thermal oil asphalt tank, you must check the bottom of the tank once a year to determine whether the thermal oil asphalt tank needs cleaning. After half a year of use, you can test it. Once it is found that the antioxidants are reduced or there are impurities in the oil, you must add anti-oxidants in time, add liquid nitrogen to the expansion tank, or perform fine filtration of the thermal oil heating equipment. Hope that the majority of construction users Even if you know how to use it, you also need to know how to maintain the thermal oil bitumen tanks.

Modified asphalt equipment uses modified asphalt 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 asphalts, such as SBS, PE, EVA, etc.

How much do you know about the related applications of emulsified asphalt equipment? As a manufacturer specializing in the production of asphalt equipment, what is the production process of our emulsified asphalt equipment? Next, our staff will give you a brief explanation.

After the bitumen decanter plant is installed, you need to check whether its interfaces are firm and precise, whether the operating components are mobile, whether the piping system is smooth, and whether the power supply wiring design is It is not necessary. When loading the bitumen decanter plant equipment, please open the automatic exhaust valve so that the bitumen decanter plant can smoothly develop and enter an electric heater. During operation, please observe the water level carefully and adjust the valve so that the water level is always connected to the appropriate adjustment position.
