Report on Joint Spacing of Concrete Pavement on T.H. 36 (S.P. 6212-62)

Experimental concrete pavement containing variations in joint spacing, reinforcement, dowel sections, and joint fillers were used on Minnesota T.H. 36 to determine optimum design. Surface rating, South Dakota Profile Surface Rating (PSR), and Concrete Pavement Evaluation System (COPES) studies were performed to evaluate the pavements. The best sections were the 15 foot and 20 foot sections with bituminous coated or rust inhibitor painted dowels. The longer sections, 33 foot and 65 foot, and the panels with sleeved dowels performed poorly. All joint fillers failed within three years.
