IMPLEMENTATION OF A COMPREHENSIVE RIGID PAVEMENT OVERLAY DESIGN SYSTEM INTO A CONDENSED OVERLAY DESIGN MANUAL. INTERIM REPORT

This report presents the development and application of a manual for the design of both rigid and flexible overlays for rigid pavements. An important feature of the manual is that it presents approximate hand solutions to typical overlay design projects in the State of Texas. This report also presents some additions to the Texas Rigid Pavement Overlay Design System. These include procedures to define design inputs and the development of charts for the structural design of overlays. Condition survey data were used to develop a technique for estimating the remaining life of an existing rigid pavement. The computer program RPRDS-1 was used to develop tables for the selection of optimal overlay strategies. Finally, a set of design charts was developed for approximate hand solutions for the design of overlay thickness.
