Title:

Asphalt Pavement Analysis with 3-D FEM Model Using Actual Tire Pavement Contact Stresses Measured with Pressure Mapping System Device

Accession Number:

01659014

Record Type:

Component

Abstract:

The load of the vehicle is transferred to the pavement through tires. Conventionally, the contact pressures are assumed to be uniformly distributed over a circular contact area. This assumption might lead to early deterioration as the stresses that are applied to the pavement are underestimated. This research aims to develop a method to analyze the actual tire-pavement contact stresses on asphalt pavement behavior in 3D FEM by using pressure mapping system device, Tekscan I-Scan. It allows indicating the precise position as well as the magnitude of the stresses applied to the pavement. The contact stresses data were processed with the help of a numerical computing tool, MATLAB. The processed data were then analyzed using 3D FEM software, ANSYS, in order to study the pavement responses. As a result, the method is successfully provided a better understanding of the effect of actual tire-pavement contact stresses on asphalt pavement responses.
