Parametric Analysis of Flexible Pavement Layers’ Accumulating Deflections

Abstract

This paper conducted a parametric analysis of the flexible pavement layers’ accumulating deflections. The accumulating process of the full-scale medium-strength subgrade (MFC) pavement layer deflections had been simulated by the previous radial basic function (RBF) model. Based on the RBF simulation results, several parameters were proposed to investigate the accumulating features of the pavement layer thickness response, the relationship between layer deflection capacity and average layer thickness, the relationship between the average thickness values of two layers and the relationship between the maximum deflection values of two layers. The analytical results revealed some unseen features of the pavement layer deflections, which provided a new way to parametrically investigate the accumulating response of the flexible pavement layers.
