Understanding how tires are used in asphalt Asphalt

Rubberized asphalt is a term applied to rubber modified asphalt with less than 15 percent by total weight of the asphalt cement. Dry process refers to mixing crumb rubber into the mixture as a small part of the aggregate or filler rather than blending the rubber with the liquid asphalt. This process is normally only applicable to hot mix

Study on Preparation Method of Terminal Blend Rubberized

Terminal Blend (TB) asphalt rubber is prepared by being sheared with high speed for a long time a high temperature and has good low temperature performance and anti-fatigue performance. But due to the aging of asphalt and desulfurization and degradation of crumb rubber, the high temperature performance of TB is not ideal. In order to propose an effective way to solve this
