The rapid growth of road traffic brings some requirements on driving comfort and safety, which include good smoothness, skid resistance and reduced noise of the pavement. SMA has adequate structure strength to reduce rutting and provide superior surface function of skid resistance. Modified asphalt as mixture binder, has considerable durability to ensure the service life with less maintenance costs. Associated with laboratory test and trial section, some suggestion and requirements are brought forward in this paper for the material properties and mixture design of SMA on the FuZhou-JiAn expressway in Jiangxi Province.
