Abstract

Mountain roads have many kinds of diseases due to their special natural and geographical conditions, and it is difficult to maintain the road surface, so it is particularly important to analyze the causes of the diseases from the theoretical aspect, in order to explore the relationship between structural mechanical characteristics and load of mountain highway pavement, the finite element simulation method was used to study the compressive stress, structural layer displacement, compressive strain, transverse shear stress, longitudinal shear stress, and longitudinal shear of different pavement structure layer depths under load. Change trend of strain. The results show that the compressive stress, longitudinal shear stress, and transverse shear stress are mainly concentrated in the surface layer and have a relatively large impact on the surface layer; the displacement value, compressive strain, and longitudinal shear strain are larger in the surface layer, and the compressive strain and longitudinal shear strain are at the joint Sudden change occurs; as the load increases, the pavement displacement, compressive stress, longitudinal shear stress, compressive strain, longitudinal shear strain, and transverse shear stress of each structural layer gradually increase, the overall structure of the pavement changes, and the probability of road damage increases. It can be seen that the changes in mechanical characteristics of asphalt pavement under different loads and different depths provide a new research idea for mountain highway pavement protection.
