Oxidized asphalt

Oxidized asphalt refers to a type of asphalt that is produced by heating crude oil or asphalt and subjecting it to an oxidation reaction with the introduction of oxygen. Oxidized asphalt can improve parameters such as the viscosity, stability, hardness, and durability of asphalt. Specifically: 1. Oxidized asphalt can increase the softening point and viscosity of asphalt, making it less likely to flow and deform at high temperatures. 2. Oxidized asphalt can improve the stability and durability of asphalt, enabling it to better resist the erosion caused by natural elements such as sunlight and rain. 3. Oxidized asphalt can also increase the adhesion and cohesion of asphalt, making it easier for it to bond with other road materials, thereby improving the stability and durability of the road surface. In summary, oxidized asphalt is a very important road material that can **improve the quality and service life of roads. .
