Product introduction:

Bitumen 60/70 is a black or brownish black viscous liquid derived from petroleum. The "60/70" in its name represents the range of needle penetration at a specific temperature, which is an important indicator of the hardness and viscosity of the asphalt. Asphalt 60/70 has good adhesion, durability and water resistance, so it has a wide range of applications in many fields.

Application

Asphalt 60/70 plays an important role in road construction and maintenance. It is mainly used to lay and repair all kinds of roads, including highways, urban roads, airport runways and so on. In the construction process, asphalt 60/70 is mixed with mineral materials (such as sand and stone) to form asphalt mixture, which has good plasticity, stability and durability, and can effectively improve the service life of the road surface and driving safety. Specifically, the application of asphalt 60/70 in road construction includes the following aspects: 1. Laying new road surface: In the new road project, asphalt 60/70 as the main bonding material, mixed with minerals and laid on the roadbed, forming a smooth, durable road surface. 2. Repair damaged pavement: For damaged or aged pavement, asphalt 60/70 can be used to repair. The repaired pavement can quickly restore its function and improve the efficiency of road traffic. 3. Road maintenance: Regular maintenance and construction of asphalt 60/70 on the road surface can extend the service life of the road surface and reduce traffic accidents caused by road damage.
