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.

According to statistics, among the high-grade highways that have been built and opened to traffic in my country, about 80% are asphalt pavements. However, with the development of time, the influence of various climatic and environmental factors, and the high-intensity driving load, the asphalt pavement will have different degrees of degradation or damage. Pavement maintenance is to take effective technical means to slow down this degradation, so that the pavement can provide good service quality during its service life.

Emulsified asphalt equipment is a special equipment for producing emulsified asphalt. The emulsified asphalt produced by emulsified asphalt equipment is used in many industries. I wonder how much you know about the emulsified asphalt produced by emulsified asphalt equipment. Let’s take a look at them one by one:
Slurry seal is a cold mix asphalt mixture with the advantages of aggregate and asphalt mixing. Under normal circumstances, similar graded slurry seal has a higher modulus than hot mix asphalt mixture, so it is often used to fill road rutting. The higher stability has a higher resistance to deformation. The mixture is usually composed of harder fine aggregate grading and wear-resistant aggregate with high sand equivalent, especially micro-seal and polymer-modified seal. This greatly increases the strength and integrity of the road surface. This makes the road surface have high wear resistance and excellent deformation resistance. Emulsified asphalt emulsion is also easy to use on a mobile slurry seal paver, where mixing and admixtures are used for chemical control to meet maintenance needs.

The advantages of Sinoroader bitumen decanter equipment over similar domestic equipment are reflected in the following points:
