The paper presents the results of a study to quantify the deterioration of a diamond ground continuously reinforced concrete pavement (CRCP) surface in terms of macro-texture, skid resistance, surface roughness and pavement noise over time. The influence of site specific features such as traffic speed and load, pre-texturing prior to the grinding operation, lane, wheel path, and trafficking direction on the deterioration of the surface properties is considered. The four surface properties were measured immediately after the grinding operation and at three subsequent time intervals after 4, 9, and 15 months. Panel data analysis incorporating fixed effects is implemented to evaluate the influence of the site specific features on the deterioration of the surface properties. The study provides statistical evidence of deterioration. A significant reduction in macro-texture and skid resistance was apparent. An increase in noise was evident soon after grinding. No significant change in roughness was found. The changes in the surface properties appear to be related to traffic over time but do not appear to be influenced by the pre-existing texturing prior to grinding. Additional monitoring of the sections is recommended to better characterize the long-term benefits of diamond grinding as a rehabilitation strategy for CRCP.
