Abstract

"The paper describes methods for predicting the reilient (elastic) modulus of unbound granular base and subbase materials used in flexible pavement construction based on California Bearing Ratio (CBR) and/or other test data. Current pavement design methods employ relationships that estimate the resilient modulus from CBR results. The most commonly referenced of these relationships are limited in that they were developed using roadbed soils with CBR values no larger than approximately 15%. Therefore, it could be helpful if a model were available that would reliably predict the resilient modulus over a wider range of CBR values and be more specific to unbound granular materials. In this study, four different Missouri aggregates were analyzed that are commonly used in pavement base layers. Two of the aggregates were gravels and two were crushed stone."--Abstract, page iii.
