Environment protection and sustainable development are recognized to be more and more important in the construction of road engineering. For this reason, a new kind of mixture-warm mix asphalt (WMA) is put forward，whose mix temperature lies between hot mix asphalt (HMA) and cold mix asphalt (CMA). Moreover, WMA may be compact in lower temperature without sacrificing performance. The review is focused on research and application of warm mix asphalt in China. And a few problems in application of warm mix asphalt are stated.
