Analysis of Mechanical Properties of High Toughness and Paving Structure of Heavy-load Traffic Trunk Highway
In order to reasonable analyze the mechanical performance of high toughness overlay struc-tures on trunk highways under heavy traffic,relying on the entity engineering and using the pavement mechanics calculation program,the mechanical properties of two types of high toughness overlay structures were analyzed.The results show that the pavement combination has important influence on the structure,and has little effect on the position of the transition point between tensile and compres-sive strains.In addition to the deflection of the road surface,the other stress indicators of the high toughness overlay structure on the road surface are better than those of the ordinary semi-rigid struc-ture,and the influence of the old road modulus on the stress of the high toughness overlay structure is greater than that of the conventional semi-rigid base structure.
