Continuously Reinforced Concrete Overlay of Existing Continuously Reinforced Concrete Pavement

摘要

This report describes the design and construction of a 6-inch thick unbonded continuously reinforced concrete (CRC) overlay of a 20-year old continuously reinforced concrete pavement (CRCP) along with crack surveys for the first nine months after construction. This is the first time (to the author's knowledge) a CRC overlay has been placed over an existing CRCP. The existing CRCP was an experimental project when built. It had several features being tried for the first time in Mississippi, one of which led to the need for the overlay.
