Polymer Concrete for Precast Repair of Continuously Reinforced Concrete Pavement on IH 30, Near Mt. Pleasant

摘要

This report describes two punchout repairs made in a continuously reinforced concrete pavement (CRCP) using precast portland cement panels. The two repairs, one 12 foot by 12 foot, the other 6 foot by 6 foot, were completed and opened to traffic in one afternoon. This technique provides a rapid method of repair that produces a repair that is structurally as good or better than the surrounding pavement. With a trained crew, the repair time can be reduced and thus reducing lane closure time. Since lane closure time is a critical consideration in high volume highways, this method will be cost effective in those areas.
