LIME TREATMENT OF ASPHALT TO REDUCE AGE HARDENING AND IMPROVE FLOW PROPERTIES (WITH DISCUSSION)

This paper examines the effects of lime on asphalt age-hardening. The study takes into account the effects of both lime type and concentration and asphalt composition (source). The effects of lime on asphalt stiffness at higher temperatures and on asphalt low-temperature flow properties are also evaluated. High-temperature stiffness and low-temperature flow properties are important in controlling permanent pavement deformation and thermally-induced cracking.
