Abstract:

This research project compared the performance of a 0.68-mile long continuously reinforced concrete pavement test section before and after receiving next-generation diamond grinding (NGDG). The test section was transversely tined and located on Loop 610 in Harris County, Houston, Texas. It included the two rightmost lanes on each traffic direction. Texas Department of Transportation (TxDOT) collected sound intensity, skid resistance, ride quality and macrotexture data before grinding, as well as 3 and 6 months after construction. Equipment was: laser scanner, locked wheel trailer, and on-board sound intensity (OBSI). The analysis methodology consisted of a preliminary investigation to verify data consistency and homogeneity, followed by a comparative analysis of pre- and post-NGDG performance. The NGDG surface significantly improved the skid resistance as well as the ride quality of the test section analyzed. Macrotexture showed a less significant improvement; however, the macrotexture analysis was inconclusive due to some possible issues with the data. The test section overall sound intensity decreased from 107.6 to 101.7 dBA, a value that recent studies consider within the quietest possible range for non-porous concrete pavements. The mathematically correct subtraction of 107.6-101.7 dBA, when converted back to decibels, removes 106.3 dBA from the environment. This amount of noise between a sports event and a rock band. This is also equivalent to a 75% reduction in noise level. Under the simplifying assumption that all vehicles produce the same noise, the NGDG surface needs 4 times more traffic to generate the same noise as the previous surface.
