REINFORCEMENT OF FLEXIBLE PAVEMENTS - DESIGN OF FINITE ELEMENT MODELS

The effect of a reinforcement inside a flexible pavement can be investigated best by the Finite Element Method. In this paper a road structure reinforced with a steel net in the bound layers has been designed based on a three-dimensional finite element model. The aim of these FEM calculations is to investigate the effect of a reinforcement under vertical traffic load by comparing stresses and deformations of unreinforced and reinforced systems under different temperature conditions. Hereby the size and the position of the net-structure inside the construction and the total thickness of the pavement system are varied. Depending on the position of the reinforcement, different aims can be pursued. With placing the reinforcement in the upper layers rutting can be delayed whereas bearing capacity can be increased by putting the net-structure at the bottom of the asphalt base course.
