EVALUATION OF PAVEMENT BEARING CHARACTERISTICS USING FLORIDA LIMEROCK BEARING RATIO TEST
A laboratory study performed to evaluate pavement bearing characteristics by the Florida limerock bearing ratio (LBR) test is presented. The LBR is a modification of the California bearing ratio test and has been widely used in Florida for the design of pavement structures. The LBR evaluation is part of a larger research project studying existing pavement conditions in Florida. A field experimental program was recently conducted on 20 selected pavement sites across the state of Florida. The LBR test was performed on pavement soils obtained from the field test sites. The LBR test results were analyzed and compared with the field test results. The AASHO Road Test layer coefficient values and soil support values (SSVs), which have become classic reference values over more than two decades, were evaluated by using the LBR and field test results. It was concluded that the LBR values could be used to estimate the SSVs for the design of flexible pavements in Florida. The correlation relationships between the LBR values and SSVs were evaluated to better characterize the pavement structures in Florida.
