Researchers for Virginia DOT investigated the reasons for premature failure of concrete patches on continuously reinforced concrete pavement. Testing revealed that the use of high early strength mixes with high cement contents and failure to assess the overall pavement condition were the most frequent causes of early patch failure. The study recommended revisions to VDOT’s concrete patching procedures.
