INVESTIGATION OF "D" CRACKING IN PCC PAVEMENTS--PHASE 3--FINAL

This report investigates the significane of specific design change which were made in an attempt to eliminate or reduce the occurrence of D-cracking on Portland Cement Concrete Pavements. This report covers Phase 3 or the field performance study of this investigation. The reduce maximum size coarse aggregate was shown to be a positive measure to reducing the rate of occurrence of D-cracking. A 4 mil polyethylene moisture barrier placed under the pavement did not show significant reduction in the occurrence or the rate of formation of D-cracking to warrant its continued useage. The use of a cement treated compacted granular base in an area of a possible high water table and slightly unstable fill resulted in accelerated occurrence and rate of D-cracking.
