Jointed concrete pavements are designed and constructed to provide long periods of service to the traveling public. In the harsh climate of Minnesota, older generation concrete mix designs, like those specified by MnDOT in the early 1990s, have demonstrated a trend where significant joint distress begins to appear on the surface of the pavement at approximately 17 to 20 years of age. The original concrete pavement test sections at the MnROAD facility, constructed in 1993, utilized older generation concrete mix designs. Following the general trend, by 2011 several of the original concrete pavement test sections that remained in service began to exhibit materials related distress along the joints. To keep the test sections in service and safe for the traveling public, partial-depth joint repairs were performed.
Learning Objective:
The materials used in partial-depth concrete repairs are constantly being tested and improved, such that the repairs last longer and can be placed and opened to traffic more quickly. The need for partial-depth concrete repairs at MnROAD provided a good opportunity to evaluate both existing and new types of patching materials. This course describes the 3-year performance of 93 patches with 22 different materials.
