Development of an Asphaltic Concrete Overlay Design Procedure for Rigid Pavements in Indiana. Executive Summary
An overlay study was conducted of thirty jointed reinforced concrete pavements (JRCP) and thirteen continuously reinforced concrete pavements (CRCP). These pavements were selected from the Indiana primary highway system based on an experimental design for levels of major factors affecting pavement performance. An analysis was made of pavement deflection; condition; serviceability; materials; thicknesses; truck traffic; latest overlay thickness; age; climate zone and subgrade type; density and moisture content. Initially, a rational analysis was planned using a back calculated material properties as suggested in the 1986 AASHTO Design Guide. However, this approach was not successful and alternate analysis procedures were utilized. A statistical analysis was performed on the CRCP pavement data, and an overlay model was developed. However, because of the limited range in thickness, truck traffic, etc. the equation should be used only as a guide for determining overlay thickness.
