Various tests of raw materials must be carried out before construction of the slurry sealing truck, and it can be used only after passing the inspection. It is necessary to conduct various experiments on the mixture before construction. Only when it is confirmed that the material has not changed can it be used. During construction, according to changes in the residual content of the emulsified asphalt and the moisture content of the mineral material, it is necessary to adjust the cooperation ratio in time to make it meet the specified requirements, ensure the workability of the slurry mixture, and proceed with the construction.

The asphalt gravel synchronous sealing truck is one of the pavement maintenance technologies. It spreads (sprinkles) asphalt binder and aggregate simultaneously within the same second, ensuring considerable surface coating strength between them. It has the characteristics of cost saving, highly wear-resistant surface, highly anti-slip surface, strong waterproofness, extended road service life, and quick recovery of traffic.

Before looking at the problem, let’s first understand the specific structural components of the asphalt spreader truck: the spreader truck consists of a car chassis, asphalt tank, asphalt pumping and spraying system, thermal oil heating system, hydraulic system, combustion system, control system, pneumatic System and operating platform composition.

The asphalt mixing plant is a special unit for preparing asphalt. It contains many devices, and the dust filter is one of them. In order to meet the requirements of asphalt mixing, what technical features does the dust removal and filtration here have?

The base layer of asphalt pavement is divided into semi-rigid and rigid. Since the base layer and the surface layer are materials of different properties, good bonding and continuity between the two are the key requirements for this type of pavement. In addition, when the asphalt surface layer seeps water, most of the water will be concentrated at the joint between the surface layer and the base layer, causing damage to the asphalt pavement such as slurry, looseness, and potholes. Therefore, adding a lower seal layer on top of a semi-rigid or rigid base layer will play a vital role in enhancing the strength, stability and waterproofing capabilities of the pavement structural layer. The more commonly used one is to use asphalt gravel synchronous sealing technology.

Compared with the traditional definition of hot and high-temperature recovery raw materials for emulsion bitumen machine, the method of recovery using normal temperature or low-temperature hot raw materials is cold patching. The common recovery raw materials are cold patching raw materials.
