Analyze the Flexible Property for Pavements with Various Axle Loads and Different Reinforcement Layers

Abstract

Flexible pavements become significant structural elements, which are really vulnerable to the probable damage resulting from various traffic loads and an aggressive environment. In order to bolster the structural strength and prolong the life of pavements, reinforcement layers have been included in the design of most roads and highways. In this research, which is based on numerical simulations, the behavior of flexible pavement with respect to varying loads and with different reinforcement layers will be analyzed. The main objectives of this article are to develop a pavement layers model by utilizing finite element software, which is ABAQUS software package, evaluate the influence of different geogrid properties, location on the induced deformation, stresses, and strains into pavement layers and evaluate the influence of different loading values considering low, medium, and high traffic axle loads. The study reveals that stress on flexible pavements is directly proportional to load force, with stresses reaching 777 KPa at 44 KN and 1390 KPa at 80 kN. Deformations vary, with values ranging from 0.00307 mm at 44 KN to 0.00946 mm at 133 kN.
