Performance of Warm Asphalt Mixture Modified by New Additives
Warm mix asphalt (WMA) has been increasingly applied in pavement projects because it is environmentally friendly and low carbon. Therefore, more and more WMA additives appeared on the market. In order to validate the new domestic warm mix additive's pavement performance, in this paper, the new additive (A or B) made in China is added to the mixture (AC-13, AC-20), and the mixture's pavement performance is tested. The test results show that the mixing and compaction temperature of mixture could be decreased by 30~40°C if additive A or B is used, and thus it achieves the effect of energy saving and emission reduction. And the mixture's performance indicators meet the requirement in current specification. In addition, compared with the corresponding HMA, the low temperature performance and fatigue performance of WMA containing additive A or B are improved.
