Project description

Michigan has been constructing jointed plain concrete pavement (JPCP) overlays since the mid-1990s and has generally had good results. However, some recent overlays showed signs of premature distress, including longitudinal cracking after the first year. Eight overlay segments with varying levels of performance (good to bad) were investigated to try and determine the cause of this distress and what actions can be taken to prevent these types of early failures.
