Book excerpt: This report details the results of an in-depth study of methods and costs of repairing failures in continuously reinforced concrete pavement. The study was conducted in 1977 by teams of Engineers from four States: Arkansas, Louisiana, Mississippi, and Texas. Similarities were revealed in the methods of repair used by maintenance personnel in the four States. Subtle differences were also discovered which can be considered for implementation by all of the participants and others to improve their maintenance techniques.

This book was released on 1982 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Procedures for permanently patching and for pressure grouting of continuously reinforced concrete pavement have been developed. These procedures have been extensively field tested to ensure their practicality and adequacy. The patching procedures reduce costs and lane closure time by considering the different distress types, different methods of construction, and concrete additive and curing for early opening. The pressure grouting procedures provide for a restoration of support beneath the slab and the prevention of future pumping.

This book was released on 1958 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paper 1: Experience gained from existing continuously reinforced concrete pavements is now adequate to suggest certain design principles. Paper 2: In the fall of 1956, the Pennsylvania Department of Highways constructed the first of two experimental continuously-reinforced concrete pavements. The first of these projects is on route 111, near York. In this project, measurements are being made of the strain in the bar-mat reinforcing steel in a uniform 9-in. pavement. Studies are also being conducted on the crack frequency, the crack width, and the slab temperature. A theory governing the behavior, the details of construction and instrumentation, and the results obtained during the first two months of the pavement's life are described.

Available in PDF, EPUB and Kindle. Book excerpt: The performance of concrete patches in continuously reinforced concrete pavement in Virginia varies from less than 1 year to many years. The purpose of this study was to determine the causes of premature repair failure in continuously reinforced concrete pavement. Four pavement sections were monitored for patching operations. Mixture designs had high cementitious material contents. The patches were typically constructed with a short lane closure time, often at night, with only about 5 to 8 hours of cure time before opening of the roadway to traffic. The strengths were determined using the temperature matched curing system. The observations and testing indicated that the two of the most significant causes for premature failure were (1) the use of high early strength concrete mixtures with high cement contents that cause excessive thermal and shrinkage cracking, and (2) failure to assess the overall pavement condition, which could have led to an overlay with structural improvement rather than just patching. Some other areas of concern were cutting of the continuous reinforcement, reestablishing the continuity of the reinforcement in the patch, damaging concrete adjacent to the patch during concrete removal, poor concreting practice with respect to proper consolidation of the concrete near the joint, and opening to traffic before adequate concrete strength was achieved. Based on these findings, the study recommended revisions to future special provisions for concrete patching and the VDOT Materials Division Manual of Instructions, Chapter 6.

Available in PDF, EPUB and Kindle. Book excerpt: Continuously reinforced concrete pavement (CRCP) is enjoying a renaissance across the United States and around the world. CRCP has the potential to provide a long-term, "zero-maintenance," service life under heavy traffic loadings and challenging environmental conditions, provided proper design and quality construction practices are utilised. This book provides an overview of the CRCP technology and the major developments that have led to what are referred to herein as the "best practices" for CRCP design and construction. The purpose of this book is to provide the best practices information on rehabilitation strategies for extending the service life of continuously reinforced concrete pavements (CRCP). The procedures described in this book consist of defining the problem, identifying potential solutions, and selecting the preferred alternatives.
