Performance of a Thirty-Two Year Old Concrete Pavement

摘要

The report reviews pavement performance testing results on an experimentalconcrete pavement built on Minnesota T.H. 36 in 1958 that contains variations in joint spacing, reinforcement, dowels, and transverse joint fillers. South Dakota Profile Serviceability Rating (PSR), Minnesota Structural Rating (SR), and Concrete Pavement Evaluation System (COPES) surveys conducted in 1990 revealed that the best performing sections were the 15 foot (4.6 m) and the 20 foot (6.1 m) sections with bituminous coated or rust inhibitor painted dowels. The longer sections, 33 foot (10 m) and 65 foot (20 m), and the panels with sleeved dowels performed poorly. All transverse joint fillers, which included 'Presstite 77' and rubber asphalt Minnesota Spec. 3723, failed within three years. Researchers previously studied the sections from 1959-1969, and the report references several memos and letters on the pavement's performance. The four basic pavement sections include: 15 foot (4.6 m) and 20 foot (6.1 m) unreinforced sections with one undoweled and three different dowel segments, and the 33 foot (10 m) and 65 foot (20 m) reinforced sections with one undoweled and three different dowel segments, and the 33 foot (10 m) and 65 foot (20 m) reinforced sections with three types of mesh and three different doweled segments.
