• Abstract:
  From the nineteen sixties to the nineteen eighties, the Mississippi Department of Transportation (MOOT) constructed continuously reinforced concrete pavements for almost all of its rigid pavement construction. The design load has been exceeded on most of this pavement type and has already received or will soon require major rehabilitation or reconstruction. Most of this CRCP is on the interstate or principal arterial systems where frequent maintenance is both costly and extremely hazardous. Tn view of these facts, it is of great interest to MOOT to develop cost - effective ways to rehabilitate or reconstruct the network of this pavement type. Federal Aid Project No. 54-0055-03-067-l I, 12, 13 is a 14.2 mi. long CRCP rehabilitation/ reconstruction project located on divided four-lane Interstate 55 in Montgomery, Carroll and Grenada Counties in North Mississippi. The rehabilitation design for the southbound lanes involved repair of working punchouts and then overlay with HMA. Eight 500 ft-long test sections were evaluated in this direction. Each lest section received a uniform thickness of overlay throughout its length with the thickness among the sections varying from 1 .4 in. to 6.4 in. The reconstruction design for the two northbound Lanes included the installation of edge drains, rubberization of the 8 inch thick CRCP surface and the placement of G.5 in. or HMA over the rubberized concrete.
