• Abstract:
  The performance of continuously reinforced concrete ; pavement (CRCP) has been quite satisfactory in Texas, ; providing one of the most cost-effective pavement systems ; for the Texas Department of Transportation (TxDOT). ; However, distresses do occur occasionally. Once distresses ; occur, they need to be repaired in a timely manner, and the ; repair cost is relatively high. Extensive field performance ; evaluations of CRCP in Texas conducted under the TxDOT ; rigid pavement database project indicate that the majority ; of the distresses are not necessarily due to the deficiencies ; in the structural capacity of CRCP. Rather, the majority of ; distresses are due to imperfections in materials and ; construction quality. These distresses normally occur ; earlier than structural distresses caused by fatigue failure ; of concrete. Accordingly, they are termed premature ; distresses (PMDs). Traditional ways of strengthening the ; pavement system, such as the use of increased concrete ; slab thickness, do not reduce the frequency of PMDs. ; The repair cost of CRCP is higher than that of jointed ; concrete pavement (CPCD), and there is little difference in ; the repair cost between PMDs and normal structural ; failures. Also, repair of CRCP distress takes longer to ; complete than CPCD repairs, causing traffic delays and ; increasing user cost. It is desirable to identify the ; mechanisms of PMDs and develop means to prevent or ; minimize the occurrence of PMDs.
