Eight kind of typical asphalt pavement's applicability research for northern warm zone continental climate regions

摘要

in order to find a suitable pavement and develop a reasonable pavement design method for southern warm continental climate regions, both experiment roads and finite element simulations are employed in this research. In experiment roads, strain detectors are buried at the bottom of asphalt layers to measure its strains and calculation models. Road design parameters such as road surface deflections and damage predictions such as plastic permanent deformations are calculated and compared between different pavements. Pavement deformation and design control parameter are made. Finally, a suggested reasonable pavement satisfying climate conditions and traffic flow needs is proposed.
