Performance Study of Continuously Reinforced Concrete Pavement and Patching Areas - I-70
This investigation reviewed the performance of the Continuously Reinforced Concrete (CRC) pavement and patching areas on I-70, Maryland, to determine the variables that affect performance. Preconstruction data was collected and reviewed. Field observations included a visual distress survey and crack survey, as well as a study of pavement deflection. To demonstrate the relative significance of crack spacing, load transfer, support conditions and other variables upon the CRC performance, a computer simulation was conducted using MARS (Multi-layer Analysis of Rigid Slabs) computer program. Results showed the failures were primarily confined to the outside shoulder lanes. Percentage reinforcement, reinforcement depth and pavement thicknesses were within specification requirements. Although numerous voids were found in the lower half of the slab and near reinforcement bars, these discontinuities did not contribute significantly to failure. High contents of fines in the subbase material led to poor drainage characteristics, which may have significant effect on the performance.
