IMPLEMENTATION OF NEW OVERLAY DESIGN PROCEDURE IN TEXAS

A project is under way in Texas to adapt a version of the rigid pavement overlay design procedure developed for the Federal Highway Administration by Austin Research Engineers, Inc., into standard Texas State Department of Highways and Public Transportation (SDHPT) practice. This project is part of a cooperative research program between Texas SDHPT and the Center for Highway Research at the University of Texas. This paper provides some feedback on the use of this procedure and documents its successful application to an interstate rehabilitation and widening project in San Antonio. This project was unique in the sense that thickness and reinforcement designs were required for five different composite pavement structures that, by their nature, are not suitable for design by past empirical methods. In documenting the designs, the selection of design criteria, characterization of material properties, and thickness design recommendations for each section within the project are discussed. The paper provides a general description of the design procedure, discussion of the results of the design, conclusions about the applicability of the design model, and recommendations for further work. The validity and practically of the new procedure, as well as its applicability for nationwide use, are noted.
