Experimental Rehabilitation of Jointed Portland Cement Concrete Pavement
A study of innovative rehabilitation techniques was initated by the Wisconsin Department of Transportation in 1981 on a section of I-90 in Dane County. Eight different, full depth, full lane width, PCC patching techniques were used with patch lengths of four, five, and six feet, with a few longer ones included. The patching techniques included cast-in-place (with and without load transfer), patches with an undercut lip beneath the existing pavement, and with perpendicular and skewed transverse joints. After patching, one dual lane pavement was intermittently diamond ground and the other dual lane pavement was continuously ground. Several shoulder rehabilitation techniques were used, including cold recycling, heater scarifying, and spot patching. One-half of the cold recycled and heater scarified sections were surface sealed with a fog seal. A slurry seal was used on the remaining sections. After one year of performance it is apparent that those patches with load transfer capability are not moving under load as much as those without. The ride quality of the continuous ground pavement remains much better than that obtained for the intermittently ground pavement.
