Abstract

In order to explore the rut change law of multi-asphalt pavement structure of heavy-duty highway, the influence of actual traffic axle load on pavement design life is studied by analyzing the measured traffic axle load of heavy-duty highway and comparing the difference between actual and designed axle load. The ruts of different pavement structures and different lanes were compared to study the rut distribution law of four asphalt pavement structures of heavy-duty highway, and evaluate the rut performance of four asphalt pavement. It can be obtained that the traffic volume predicted at the time of design is much lower than the actual traffic volume. Compared with the cumulative action times of the equivalent designed axle load with the original design life of 15 years, the measured axle load spectrum is expected to reach the designed service life in the 6.2 year; The rut of the four asphalt pavement structures is less than 10mm, and the rut condition of S1 is basically the same as that of S3 and S4. The average rut of S2 is slightly larger than that of the other three pavement structures because it is located at the light controlled intersection, and S4 has the smallest rut. As a fully flexible asphalt pavement structure, S3 has the same rutting resistance as S1 and S4.
