Effects of Asphalt Cement Rejuvenating Agents
Louisiana's initial work in the recycling of asphaltic concrete pavements has demonstrated the need to obtain a base of knowledge in the area of rejuvenating agents are examined with regard to the rejuvenator's effect, at various levels of addition, upon age-hardened asphalts; the subsequent aging characteristics of the rejuvenated asphalts; and the uniformity of mixing of the rejuvenating agents with asphaltic concrete mixes. Prediction equations yielding the proper quantity of rejuvenator to be added to an oxidized asphalt were examined. The rejuvenated asphalts followed anticipated patterns when tested for penetration at 77F, viscosity at 140F and 275F, and ductility at 77F. Generally, the rejuvenated asphalts demonstrated acceptable viscosity indices when subjected to the Thin Film Oven Test. Testing for uniformity of mixing in asphaltic concrete mixes proved inconclusive.
