Design and Research on the Warm-Mix Rubber-Modified Asphalt Mixture Based on the GTM Method

Abstract:

By using GTM method, with equal volume parameters as the criterion, determined the suitable temperature of Evotherm warm-mix rubber-modified asphalt mixture, and applied Marshall method for repeated experiments, holding that GTM method could increase the cooling rate. Then, it firstly proposed a two-stage design method to conduct design of warm-mix rubber-modified asphalt mixture based on the two-parameter system; on the basis of hot-mix asphalt mixture test, it carried out staged design of asphalt content and temperature to ensure the pavement performance in terms of material composition and volume parameters. Finally, the paper conducted performance test of the designed warm-mix mixture and made comparative analysis of the corresponding hot-mix mixture. The results showed that the low and high temperature performances as well as the water damage resistant performance of Evotherm warm-mix rubber-modified asphalt mixture were superior than that of hot-mix mixture, and its compression resilience modulus was roughly equal to that of the hot-mix mixture, which would not affect the pavement structure design.
