Planning, Design and Construction of an Unbonded Concrete Overlay
Prior to 1980, Illinois had constructed three unbonded concrete overlays. These overlays were constructed to incorporate portions of the existing alignment and pavement in construction of the interstate system. This report details the planning, design, and construction of a fourth Illinois unbonded concrete overlay. Three design approaches were used to determine the thickness of the overlay; the U.S. Army Corps of Engineers method published in NCHRP Synthesis 99, the AASHTO design method published in the AASHTO Guide of Pavement Structures, and an arbitrary thickness reduction from a new pavement thickness calculation based on the Illinois Department of Transportation (IDOT) Design Manual. IDOT built a 23-cm (9-in.) continuously reinforced unbonded overlay utilizing the existing bituminous overlay as the separation layer or interlayer.
