Highway construction plays an active role in economic development and construction. Over the past few decades, various highway construction projects have continued to achieve new results. Correspondingly, construction requirements for road construction machinery and equipment are also more complex. To prevent accidents from occurring during mechanized construction and ensure the safety of equipment and personnel during the construction process, safety management related to road construction machinery must be done well.

When constructing highways, the use of road construction machinery has always been a major issue worthy of attention. A series of issues such as the quality of highway completion are closely related to this. Repair and maintenance of road construction machinery are the guarantee for completing production tasks. Correctly handling the use, maintenance and repair of machinery is a crucial issue in the mechanized construction of modern highway construction enterprises.

There is also a reversing valve in the asphalt mixing plant, which generally does not cause problems, so I have not understood its solutions in detail before. But in actual use, we encountered this kind of failure. How should we deal with it?

The correct use of road construction machinery will directly affect the engineering quality of the entire highway, as well as the progress and efficiency of construction, etc. Effective maintenance and upkeep of road construction machinery is crucial to completing the entire production task. The main guarantee is that in the entire modern highway construction, the use of road construction machinery is very important.

atural bitumen: Petroleum is squeezed by the earth's crust for a long time in nature and comes into contact with air and moisture. Its light oil content gradually evaporates, and the petroleum bitumen formed by concentration and oxidation is often mixed with a certain proportion of minerals. Natural bitumen can be divided into lake bitumen, rock bitumen, submarine bitumen, oil shale, etc. according to the environment in which it is formed.
Rock bitumen is an bitumen-like substance derived from ancient petroleum seeping into the cracks of rocks, and after hundreds of millions of years of deposition, change, adsorption, and fusion, under the combined effects of heat energy, pressure, oxidation, catalysts, bacteria, etc.

Rubber powder modified bitumen (BitumenRubber, referred to as AR) is a new type of high-quality composite material. It is a new type of high-quality composite made of rubber powder made from waste tires, which is added as a modifier to the base bitumen. It is made through a series of actions such as high temperature, additives and shear mixing in a special special equipment. Material. It can extend the service life of the road surface, reduce noise, reduce vibration, improve thermal stability and thermal cracking, and improve icing resistance. Under the combined action of heavy traffic bitumen, waste tire rubber powder and admixtures, the rubber powder absorbs resins, hydrocarbons and other organic matter in the bitumen, and undergoes a series of physical and chemical changes to moisten and expand the rubber powder. The viscosity increases, the softening point increases, and the viscosity, toughness, and elasticity of rubber and bitumen are taken into account, thereby improving the road performance of rubber bitumen.
