Rutting Evaluation of Hot Mix Asphalt Using Finite Element Modeling Based on Viscoplastic Characteristics from Static Creep Test

Abstract

among the foremost widespread road damages is rutting in asphalt surfaces, which can be prevented or lessened with the Bailey technique. In order to estimate rut depth in hot mix asphalt (HMA) blends, this article simulates wheel track testing using the two-dimensional (2D) as well as three-dimensional (3D) finite-element method (FEM). It then connects these characteristics with an accelerated performance testing tool. In order to simulate the viscoplastic properties of bituminous mixes, static creep experiments are conducted on several samples to determine the substance parameters of the creep power law. The Hamburg wheel rut tester (HWRT) can be utilized to calibrate material characteristics produced in a static creep test and rut asphalt laboratory-accelerated rutting resistance analysis. HWRT is simulated using finite-element programs, and results from the model have been compared with the results of the experiment. According to the findings, there is a range of 0.2 to 6.6% between the predicted and actual rut depths in the laboratory's measurements.
