Continuously Reinforced Pavements: Punchouts and Other Distresses and Implications for Design
Causes for distress in continuously reinforced concrete pavements were determined. Primary types of distress leading to reduction in service were punchouts and crack spalling. Causes for both the punchout and spalling distresses were determined to be loss of load transfer across the cracks. Loss of load transfer over time was correlated with the crack opening and loss of uniform support due to erosion and pumping of the subbase. Crack opening was correlated with crack spacing. A design procedure is proposed based on the capability of the system to transfer load across the cracks. The design procedure is dependent on crack spacing. Consequently, it is necessary to be able to predict crack spacing before the design procedure can be applied. While crack spacing can be controlled to some extent by the amount of reinforcing steel used and steel placing, the dominant factor in crack spacing appears to be climatic conditions at the time of construction. To develop a reliable design procedure for continuously reinforced pavements, it will be necessary to provide a controlled crack spacing.
