What is CBR Value Estimation for PMGSY Roads about?

This document discusses methods for predicting California Bearing Ratio (CBR) values, which are used to design flexible pavements. CBR testing requires large soil samples and time, making it difficult to evaluate subgrade strength over long roads. The document examines previous studies that developed correlations to predict CBR from other simple tests. It then analyzes 10 soil samples from rural road projects in West Bengal, India to validate methods from IRC:SP:72-2007 for predicting CBR based on soil clas
