Research on the Integration of Structural Design and Material Parameters of Long-life Asphalt Pavement

Abstract

In order to reduce the disease risk stemming from asphalt concrete pavement and ensure the safety of road operation, we should pay attention to the structural design of long-life asphalt pavement, strengthen the selection of long-term pavement materials, scientifically set the pavement mechanical performance indexes based on the calculation results of pavement structure thickness combination and modulus combination, and ensure the stability and durability of road pavement structure through the real-time establishment of three-dimensional finite element calculation model, as well as the integrated design that takes into consideration the aspects of road subgrade, semi-rigid base and asphalt layer.
