| 摘要： | The Strategic Highway Research Program's project H-106, the partial-depth spall-repair experiment, is the most extensive effort to date to evaluate the performance of various rapid-setting materials and procedures used in the repair of partial-depth spalls in Portland cement concrete pavements. Four test installations consisting of a total of 1,607 patches, were constructed in 4 climatic zones, and the experiment investigated the performance of several cementitious, polymeric, and bituminous patching materials, and procedures used in repairing jointed concrete pavements. The techniques included the follwoing: saw and patch, chip and patch, mill and patch, waterblast and patch, and minimal praparation clean and patch under adverse conditions. The patch performance has been good: only 2.3% of the patches have failed. |
