Performance Evaluation of Warm Asphalt Mixtures

Jul 07, 2021  Warm mix asphalt (WMA) is one of the ways to lower the production temperature without compromising the workability and performance of the mixture [ 9, 10, 11 ]. The temperature reduction range in WMA is typically around 20–40 °C compared to conventional HMA temperature (140–190 °C) [ 9 ].
