STUDY OF D-CRACKING IN PORTLAND CEMENT CONCRETE PAVEMENTS, VOLUME 3--AIR PHOTO PHASE

This study was undertaken to determine if staining associated with "D" cracking in concrete pavement could be detected and evaluated by aerial photography. Staining was detected and measured and the areal extent found to indicate a degree of deterioration within individual projects. A significant decrease in strain area was also noted when metropolitan traffic was present. This reversal was attributed to abrasion by studded tires. Pavements constructed with sawed and undowelled transverse joints 30 feet (9.1 m) apart exhibited less stain and D-cracking but more roughness due to joint faulting than sawed and dowelled joints spaced 61.5 feet (18.7 m) apart. /FHWA/
