AbstractThis study was initiated in response to the development of early distresses in the patch material of a dowel bar retrofit(DBR) project located in Marshfield, Wisconsin. Primarily, the slightly modified Mn/DOT 3U18 patch material used onWisDOT's DBR project exhibited microcracking and debonding from the sidewalls of the DBR slots. These distresses are aresult of shrinkage. Since the Mn/DOT 3U18 patch material is significantly less expensive than other proprietary rapidsetting patch materials and its components are readily available, WisDOT deemed it worthwhile to seek an inexpensiveway to improve the performance of the material.Three main concepts were identified as possible techniques for reducing shrinkage in the Mn/DOT 3U18 patch material:expansive cements or additives, shrinkage reducing admixtures, and internal curing through the use of saturatedlightweight fine aggregate. The 11 products used to modify the Mn/DOT 3U18 patch material in this study were Type Kcement, Komponent, Denka CSA #20 (50.56 lb/yd 3 or 30 kg/m 3 ),DenkaCSA#20(42.14lb/yd 3 or 25 kg/m 3 ), Denka CSA100R (50.56 lb/yd 3 or 30 kg/m 3 ), Denka CSA 100R (42.14 lb/yd 3 or 25 kg/m 3 ), Peramin SRA330, Eclipse Plus, TetraguardAS20, Solite, and Hydrocure. Sealtight 2255-White, a poly-alphamethylstyrene-based concrete curing compound, was alsoevaluated for its effectiveness in preventing water loss from the surface of the patch material in comparison with Sealtight1600-White, a water-based, wax-based curing compound.After extensive laboratory testing, it was found that only the Denka CSA #20 product, at a 50.56 lb/yd 3 (30 kg/m 3 ) dosagerate, and the Tetraguard AS20 were able to successfully reduce shrinkage in the Mn/DOT 3U18 patch material withoutnegatively impacting other vital properties required for concrete patch materials. Patch material containing Denka CSA #20is approximately 10 percent less expensive than patch material containing Tetraguard AS20, but both products providesignificant cost savings when compared to some proprietary rapid setting patch materials. It was also found that theSealtight 2255-White showed 69% less water loss than the Sealtight 1600-White, but is also three times more expensivethan the Sealtight 1600-White. Both curing compounds, however, met WisDOT specifications for both water retention andreflectance.17. Key Words 18.
