Evaluation and Revision of Texas Highway Department Rigid Pavement Design Procedure.

摘要

Recent experiences with the performance of concrete pavements in Texas have been of major concern to design engineers,who have pointed out that greater thicknesses of pavements than those predicted by the current design manual should be used. The report revises the current design manual and presents a new procedure for the design of portland cement concrete pavements. The procedure is based on information obtained from various research projects of the Texas Highway Department as well as the experience and ideas of THD design personnel. The report summarized the findings that may be implemented immediately by the Texas Highway Department. The draft of recommended revisions and design details has been prepared in a form in which they can be included in the design manual with a minimum of effort. The recommended revisions provide an incremental step towards use of the Rigid Pavement System (RPS),developed for the Texas Highway Department under Project 1-8-69-123,since these revisions contain many of the concepts that are used in RPS.
