Structural Response Analysis of Highways under Heavy Loads
As China's economic development, substantial growth in traffic, the importance of subgrade in road construction is escalated. Under the vehicle load, subgrade deformation will continue to accumulate and ultimately lead to subgrade permanent deformation. Excessive permanent deformation of subgrade soil will cause enormous economic losses, especially in rutting deformation, and have a direct impact on road performance in safety and comfort. Meanwhile, permanent deformation of subgrade will affect the structural performance of pavement, causing the other forms of damage. For example, the emergence and strengthening of reflective cracking, or accelerated fatigue failure because of too heavy tensile strain (or tensile stress) on the underside of the surface layer, and then caused great negative impact on the pavement structure and service performance. This article examines the role of high-speed heavy traffic load characteristics, and set up finite element model analysis for semi-rigid road structure, the most widely used internal road style, to obtain the mechanical response characteristics under high-speed heavy traffic loads.
