Evaluation of Pavement Material Performance Using Plate Load Test Data and CBR for Optimized Roadway Design

Abstract

This study uses data from the California Bearing Ratio (CBR) and Plate Load Test (PLT) to assess the bearing capacity and deformation properties of subgrade materials. Correlating PLT and CBR findings is the main goal in order to increase pavement design dependability. The study includes experimental testing on locally available soil that has been modified using waste tire rubber and fly ash. To determine optimal design parameters, results are investigated using empirical models and graphical representations. Twenty pertinent studies in all were examined to bolster the methodology and conclusions.
