Experiment design and construction technology of SMA pavements material

As a kind of relative new asphalts mixture combining the advantages of several commonly used asphalts mixtures, SMA has good performance in all-around. Researches on SMA has been carried out in term of experiments, mix proportion design SMA, performance evaluation, construction technology and running-after observation of the road performance in the supporting engineering project is made, which are based on traffic condition, climate envelopment and mineral aggregate resource in China Henan province. Design standard, design method, and construction technology that are suitable for Henan region are hereby suggested.
