Guidelines for Permitting Overloads. Part 1. Effect of Overloaded Vehicles on theIndiana Highway Network

摘要

A study has been conducted at Purdue University to develop a procedure forpermitting overloaded trucks in Indiana. This study was funded by the Indiana Department of Transportation (INDOT) and the Federal Highway Administraton (FHWA). As a part of this study a three-dimensional, dynamic finite element program (3D-DFEM) was used to analyze flexible and rigid pavements and develop load equivalency factors. Truck loads moving at different speeds were included in the analysis and a number of material models were used to represent the actual pavement materials behavior under moving loads. The 3D-DFEM was verified for flexible and rigid pavement analysis.
