DEVELOPMENT OF PROCEDURES FOR REPLACING JOINTS IN CONCRETE PAVEMENT

Two types of concrete pavement repair procedures were developed; pre-cast slab repairs and cast-in-place repairs, both requiring full-depth sawing of the repair limits, removal of the distressed concrete without disruption of the base, and installing sealed joints at the end limits. A one-lane, previously sawed area, up to 12-ft long, can be replaced with a precast slab and opened to traffic in about 1-1/2 hours; a cast-in-place repair; using fast-set concrete in 6 to 8 hours. Although doweled joints were used on a few installations, the report describes the difficulties encountered with using them on a production basis, and undoweled joints have been used on most of the repairs. To date, repairs equivalent to approximately 7 lane miles of pavement have been made. No specific repair recommendations are made, since evaluation of the repairs is not complete. An Appendix, containing a step-by-step repair procedure, current Michigan Specifications, and various plans, is included.
