Evaluation of the Effects of Diamond Grinding on PCC Pavement Performance

Grants and Contracts Details

Description

Diamond grinding ofPCC pavements is routinely used to restore the ride quality of concrete roadways. The roadway may have become rough due to joint faulting or patching which has been required to restore the pavement structure. This type of treatment is done when the pavement structure is typically 15 to 20 years old. In recent years there has been concern that the process of diamond grinding has been detrimental to the performance of the pavement structure, due to the process of exposing the aggregate and paste structure of the pavement surface. This project will evaluate the performance ofPCC pavements which have been diamond ground to those which have not been ground to see what effects there may be on overall pavement performance. This evaluation will involve looking at the historical pavement management data, including rideability, faulting, and overall condition points. In addition, a literature review will be conducted to determine the state-of-practice with regard to utilization of diamond grinding as a maintenance alternative for PCC Pavements
