[0002] Road asphalt is asphalt used for paving roads. It is black and solid. It has good rheological properties, long-lasting adhesion, rutting resistance, and anti-pushing deformation ability. It is obtained by regular vacuum distillation of crude oil with appropriate properties, or by shallow oxidation or propane deasphalting of vacuum residue oil. It can also be obtained by blending asphalts of different ductility and penetration levels. It is mainly used for paving roads and as a binder for roofing materials. It can be used for paving high-grade highway pavement, airport runways and high-load pavement at important traffic intersections.
