| 摘要： | A study was initiated by the Wisconsin Department of Transportation to investigate the effects of spot diamond grinding on the performance and material properties of portland cement concrete (PCC) pavements. A field survey was conducted to assess the conditions of selected spot-diamond-ground PCC pavement sites. Pavement distress data were collected on control and spot-ground sections on 22 highways consisting of 34 sites in Wisconsin. In addition, microsurveys were completed for each of the spot-ground sections. Utilizing the pavement distress index (PDI) values and results of the microsurveys, comparisons are made between sections that were spot-ground and those that were not. Conclusions are drawn concerning the effects of spot grinding on the performance of the concrete pavements; no practical differences were found between the spot-ground and control sections. |
