Abstract

Curing condition plays a vital role in the performance of cold recycled asphalt concrete technology using cement and emulsion, that is, cement asphalt emulsion mixture (CAEM). Therefore, this article aimed to investigate the changes in the dynamic modulus evaluation (|E*|) of CAEM utilizing 100% reclaimed asphalt pavement (RAP) at different curing conditions. The changes in |E*| of 100% RAP CAEM at curing temperatures of 25°C, 40°C, and 60°C cured at 1, 3, 7, and 28 days were investigated. The results indicated that both curing temperature and curing time influence the test results of |E*|. Accordingly, the value of |E*| increases with the increase of the curing temperature and curing time; however, the rate of increase tends to slow down after seven days. In addition, |E*| values at different temperatures and frequencies showed that the CAEM exhibits the same viscoelastic properties as the traditional asphalt mixture.
