KANSAS CONCRETE PAVEMENT PERFORMANCE AS RELATED TO D-CRACKING

D-crack deterioration in portland cement concrete pavements was common in Kansas in the 1930's; however, no large-scale investigation was made until 1944. That survey indicated a significant relationship between coarse aggregate and D-cracking. The aggregate size was reduced and aggregate testing was improved. Another pavement condition survey was made in 1951-1952 to determine the effect of materials or designs on deterioration. Again coarse aggregate came under suspicion. For a time after this survey it appeared that there was little additional trouble with D-cracking. In 1962 deterioration was noticed in pavements less than 5 years old, and in 1964 another study was begun with objectives of determining the extent of damage, reasons for its occurrence, and effective methods of repairing existing damage and preventing future damage. This report covers pavement performance as related to the extent of damage and clues for the prevention of future damage. The following conclusions were reached: D-cracking is still a problem in Kansas. All Kansas limestones used in pavement concrete have been associated with D-cracking. Pavements with limestone coarse aggregates in excess of 35 percent were more likely to be D-cracked than pavements with less than 35 percent limestone coarse aggregates. Most of the pavements without limestone coarse aggregate were rated good except those constructed with Blue River, Walnut River, or Bazaar gravel deposits. Implementation of these results has included limiting the limestone coarse aggregate to no more than 30 percent, with a maximum sixe of 1/2 in., and using type II cement and preformed neoprene transverse joint sealers.
