POLYMER CONCRETE FOR PRECAST REPAIR OF CONTINUOUSLY REINFORCED CONCRETE PAVEMENT ON IH 30, NEAR MT. PLEASANT

This report describes two punchout repairs made in a continously 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 reduce lane closure time. Since lane closure time is a critical consideration in high volume highways, this method will be cost effective in those areas. (FHWA)
