Title: FACTORS INFLUENCING THE PERFORMANCE OF CONTINUOUSLY REINFORCED CONCRETE PAVEMENTS

Availability: Find a library where document is available Abstract: A statewide condition survey of continuously reinforced concrete (CRC) pavements was conducted in Indiana in 1972 to evaluate the effects of sub-base and subgrade type, the methods of paving, steel placement and steel fabrication, concrete slump, and traffic on CRC pavement performance. The measures of performance were extent of failures, parallel cracks with less than 30-in. (76-cm) crack spacing, random cracks, spalled cracks, and edge pumping. The results show that subbase type, methods of steel placement and steel fabrication, concrete slump, and traffic significantly influence CRC pavement performance. Gravel subbases showed poorer performance than crushed stone and bituminous stabilized subbases. Better performance was indicated where deformed wire fabrice or loose bars were used than where tied bar mats were used. Depressed steel performed better than steel preset on chairs. The data showed little difference between performance of pavements that were slip-formed and those that were side-formed. Relative to good performance, an optimum range of concrete slump between 2.0 and 2.5 in. (5.0 to 6.5 cm) was indicated. Distress of CRC pavements is associated with traffic. Most of the pumping was observed on pavements with gravel subbases, though some pumping was also indicated where bituminous-stabilized or crushed-stone subbases were used.
