LONGITUDINAL CRACKING IN A CONTINUOUSLY REINFORCED CONCRETE OVERLAY IN CONNECTICUT

The cause of longitudinal cracking that developed in the middle lane of a three-lane continuously reinforced concrete pavement was investigated. Soil borings were removed for frost-susceptibility determination. Rebound deflections were taken to ascertain amount of relative resistance to deflection offered by different base courses underlying the CRCP. Pavement cores were also removed through the longitudinal joint sawed between the middle and outer lanes, which were placed simultaneously. The latter proved beyond a doubt that insufficient depth of longitudinal cut was the primary cause for the random longitudinal cracking. /Author/
