Investigation of rutting behavior of asphalt pavement in long and steep section of mountainous highway with overloading
Highlights The strain and stress relationship under cyclic haversine load was developed. A new operational mode is proposed to obtain the vehicular load characteristics. Rut behavior under constant power load in the mountainous highway is gained. Sensitivity analysis and parameter fitting of rut impact factor are acquired. Restrictions of slope grade and length based on rutting control are conducted.
Abstract In order to investigate rutting behavior in long and steep section of mountainous highway, this paper selected generalized Kelvin model as the constitutive relationship for asphalt mixture, proposed a new method for material parameter identification, provided the tangential stiffness matrix for the generalized Kelvin model, and applied the constant power vehicular loads on the finite model. The results show that the overload, operational speed, and the tangential and vertical forces of the vehicle have a significant impact on the rutting of asphalt pavement. Based on rutting sensibility analysis, this paper also develops a confinement method of the slope grade and length in long and steep section of mountainous highway.
