Study on Pavement Performance of Warm Mix Asphalt with DAT

Abstract:

To study the difference of pavement performance between DAT warm-mix asphalt and hot-mix asphalt, the impact on the SBS asphalt with 10% DAT was studied first. Then AC-5 asphalt mixture was made the Marshall specimens according to the indoor mixing and molding temperature. Analyze the road performance between warm mix asphalt and hot mix asphalt. The experiment results show that the SBS asphalt with DAT has small difference to the original. The DAT warm-mix asphalt has poor water stability and low-temperature stability but good high-temperature stability than the hot mix asphalt when the indoor mixing and molding temperature has 20°C reduction. So DAT warm-mix asphalt can achieve the purpose of energy saving.
