Asphalt Cement an overview ScienceDirect Topics

In general, asphalt cement should be modified to achieve the following types of improvements (Roberts et al., 1996): (i) lower stiffness (or viscosity) at the high temperatures associated with construction which facilitates pumping of the liquid asphalt binder as well as mixing and compaction of asphalt mix; (ii) higher stiffness at high service temperatures, which reduces rutting and shoving; (iii) lower stiffness and
