Medium-temperature asphalt is a bituminous material with high stability at moderate temperatures. Its characteristics include good medium-temperature stability, high mechanical properties, excellent corrosion resistance, and favorable construction performance. Medium-temperature asphalt has a wide range of applications, primarily in road construction, building waterproofing, anti-corrosion engineering, thermal insulation materials, and industrial coatings.

1. Road Construction: Medium-temperature asphalt is widely used in road construction to enhance the medium-temperature stability and service life of roads. Its excellent compressive resistance and wear resistance ensure the smoothness and durability of road surfaces.

2. Building Waterproofing: Medium-temperature asphalt can be used in waterproofing projects for buildings, effectively improving waterproof performance and protecting structures from water erosion.

3. Anti-Corrosion Engineering: Medium-temperature asphalt is suitable for anti-corrosion projects, such as protective coatings for bridges, docks, and other structures, preventing metal surfaces from corrosion and damage.

4. Thermal Insulation Materials: Medium-temperature asphalt has good thermal insulation properties and can be used as insulation material, effectively extending service life.

5. Industrial Coatings: Medium-temperature asphalt can be used as industrial coatings, offering excellent corrosion resistance and stability.

Medium-temperature asphalt has a molecular weight ranging from 200 to 2000 and a softening point between 65-95°C. It exhibits good flexibility, crack resistance, and wear resistance. Compared to conventional asphalt, medium-temperature asphalt offers better high-temperature stability, oxidation resistance, and durability.
