Abstract
Three types of asphalt mixture were prepared with AC-13C mineral mixture and three types of asphalt separately.A series of laboratory tests of AC-13C asphalt mixture were conducted.The results showed that TLA modified asphalt mixture and SBS modified asphalt mixture has better high temperature stability,low temperature crack resistance and water stability than ordinary asphalt mixture.TLA modified asphalt mixture has better high temperature stability and water stability than SBS modified asphalt mixture,but its low temperature cracking resistance is slightly worse.
