Improving Surface Characteristics by Using Diamond Grinding
Publication: Recent Developments in Evaluation of Pavements and Paving Materials
Abstract
This study performed crash accident analysis both before and after diamond grinding (DG) on a recent project section. After the completion of DG, the average crash occurrence was reduced by 15%, and there was an average international roughness index (IRI) reduction of approximately 40% immediately after treatment. Eleven projects were evaluated to derive a statewide trend on various surface characteristics of pavements due to DG, with the oldest section studied approximately 8 years after treatment. Immediately after DG, the average skid number increased by about 30%. Similarly, there was an average IRI reduction of approximately 40% immediately after the DG. Depending on the existing pavement conditions, the range of IRI reduction varies from 17 to 57%.
