Influencing performances of TLA modified asphalt due to ash subsidence separation

TLA modified asphalt is seldom used in China.

With the asphalt pavement improvement works in Nanning to Youyiguan Expressway as an example,the Paper introduces how to determine the TLA modified asphalt dosage and the production method for mixture.

The proportioning design of TLA modified asphalt mixture is carried out by GTM method and its road usage performance is inspected.

Aiming at fatigue damage which is one of primary distress of now in highway asphalt pavements, the fatigue performance of TLA modified asphalt mixture was researched in the paper according to the asphalt pavement engineering in the First Loop Expressway of Fast Main Highway of Foshan City in Guangdong Province.

In combination with the application of the TLA modified asphalt in Shijiazhuang—Huanghua Expressway,this paper studies the mixture ratio design of the TLA modified asphalt mixture by means of the GTM method.

The article sums up the application conditions of TLA mixed asphalt mixture in the Renmin Road Rebuilding Project in Zhuhai City,puts forward some points for attention in its spreading technology in order to ensure the engineering quality,and puts forward some requirements for its construction joint treatment,the field inspection and the quality control.
