Abstract:The match ratios and performances of;TLA modified asphalt mixture AC-13C (TAC-13C) were tested and researched according to the asphalt pavement engineering in the First Loop Expressway of Fast Main Highway of Foshan City in Guangdong Province, Firstly, the technical performances of TLA modified asphalt with 6 kinds of different TLA mixing rate were analyzed to obtain a reasonable TLA mixing rate as 40% in a fine performance-price-ratio, Secondly, the match ratios of TAC-13C were optimized with the orthogonal experiment, and the recommended ranges of gradation are suggested to meet the technical requirements of every index. Accordingly the match ratio was designed, and its pavement performances were checked in a laboratory. Finally, the designed TAC-13C was verified in a trial road with the quality control and performances testing on the site. The results show that the designed TAC-13C is fine in pavement performances and can be applied in the heavy-traffic highways of the hot and humid southern region.
Keywords:pavement engineering  Trinidad lake asphalt (TLA)  asphalt mixture  match ratio  pavement performance
