Federal Highway Administration. Demonstration Projects Division.] -- The general objective of this project was to monitor and evaluate the performance of prestressed (posttensioned) concrete pavement. This article provides an overview of prestressed concrete pavements, focusing on issues related to the structural value of prestress in pavement design and on performance and maintenance advantages. Corporate Authors: Purdue University. School of Civil Engineering, Stadium Mall Drive West Lafeyette, IN United States Author: B F Friberg. In the original version, used in the first precast concrete pavement project in Texas, 4,5,6 base, central stressing, and expansion joint panels were used: The gap slab concept has been. improvement in the structural performance of the pavement. A comprehensive program of laboratory testing was used to estab-lish the structural performance of panels 4 1/2 inches thick and pre-stressed to a level of psi. This prdgram consisted primarily of the application of repetitive wheel loads to a prototype section of -.

Although several prestressed pavements have been constructed in the United States, the authors believe that the approaches used in these projects do not use the full potential of PCP. Other concepts should be explored that could more fully realize the benefits of PCP in highway construction. PRESTRESSED PAVEMENT THICKNESS DESIGN (DISCUSSION AND CLOSURE) A computerized procedure for thickness design of zero-maintenance prestressed concrete pavements is presented. Factors considered in developing the design procedure include traffic loading, temperature and moisture variation in the concrete slab, loss of subbase support, properties. Prestressed pavement is perhaps one of the most important yet underusedinnovations in prestressed concrete in the past century. Generally in the form of post-tensioning, prestress significantly reduces the required slab thickness and greatlyimproves pavement performance by reducing the occurrence of cracking. While thefirst reported use of.

However, a reasonably uniform interpretation of the nomenclature associated with prestressed concrete pavements is considered desirable. On this basis, a listing of brief definitions has been prepared, as follows: Prestressed Concrete Pavement. Home» Prestressed pavement performance in four states: a panel report.

Prestressed Concrete Pavement (PCP) has been around for almost 60 years. Its application started in Europe in the s, and since then it has been applied with fair success in other countries, including the United States. Domestic application of this technology has been limited for different reasons, mainly due to the lack of well-.
