In order to study the foaming process of matrix asphalt and improve the road performance after foaming,through the asphalt foaming test,Marshall stability test,rotary and compaction forming test,freezing and thaw splitting test,etc.,the viscosity change rule,compaction characteristics and road performance of foam warm asphalt mixture are systematically analyzed.It is found that the best foaming temperature of ordinary asphalt is 150℃,the water consumption is 1%and the best molding temperature is 115℃;the density and compaction performance of foam warm mixed asphalt mixture are better than those of ordinary hot mixed asphalt mixture.
