Medium-temperature asphalt is a black solid material that belongs to a type of asphalt. Its main component is carbon, and it also contains elements such as hydrogen and oxygen. The properties of medium-temperature bitumen are as follows:
Temperature characteristics: Medium-temperature bitumen is solid at room temperature, and as the temperature increases, it softens and melts, but there is no fixed melting point. Within a certain temperature range, medium-temperature bitumen can melt and flow.
Chemical stability: Medium temperature asphalt has good chemical stability and has a certain resistance to acids, alkalis, salts and other chemicals.
Thermal stability: Medium-temperature asphalt has good thermal stability, can maintain stable performance in high-temperature environment, and is not easy to decompose and deform.
4. Viscosity: The viscosity of medium temperature asphalt is moderate, with good fluidity and plasticity, which is convenient for construction and molding.
Water resistance: Medium temperature asphalt has good water resistance, and is not easy to absorb water, expand and dissolve.
6. Abrasion resistance: Medium temperature asphalt has good wear resistance and can withstand a certain degree of friction and wear.
7. Compressive resistance: Medium-temperature asphalt has good compressive resistance and can withstand a certain degree of pressure without deformation.
8. Construction performance: Medium temperature asphalt has good construction performance, can be evenly applied to the construction surface by heating and stirring, and is easy to compact.
In short, medium-temperature asphalt has good physical and chemical properties, and is widely used in the construction of roads, bridges, tunnels, airport runways and other projects.
