Asphalt - Wikipedia

The vast majority of refined asphalt is used in construction: primarily as a constituent of products used in paving and roofing applications. According to the requirements of the end use, asphalt is produced to specification. This is achieved either by refining or blending. It is estimated that the current world use of asphalt is approximately 102 million tonnes per year. Approximately 85% of all the asphalt produced is used as the binderin asphalt concrete for roads. It is also used in other paved areas such as airport run…US10662110B2 - Asphalt composition for paving roads,,Asphalt composition for road pavement, which is excellent in drying strength, strength after immersion in water, and bending strength, a method for producing the same, and a road pavingJP2003192901A - Modified asphalt composition for road,,PROBLEM TO BE SOLVED: To provide a modified asphalt composition for road pavement, which has good mixing uniformity of a modifier and asphalt and suppresses phase separation.

Asphalt compositions for different application scenarios,

Asphalt is the key material for road construction. It is, however, as versatile as there are use cases for paved roads. There is not one universal recipe for each application. It is rather the composition of components, which defines the physical properties of a road. Asphalt consists of aggregate and bitumen. The choice of binder type and quantity as well the type of aggregation play an important role in theAsphaltite- Asphaltite use in road asphalt- Asphaltite,,Yet another embodiment of the present invention is directed to a road material composition that includes an asphalt composition and aggregate.
