Failure and Repair of Continuously Reinforced Concrete Pavement


Book Description

The performance of CRCP has revealed a number of failure modes that are traceable to design, construction, materials, and maintenance deficiencies and such other factors as environemntal conditions and traffic loadings. This report of the Transportation Research Board includes a review of the cumulative experiences of state that have constructed and maintained CRCP. Guidelines for repair techniques are included, and areas of needed research are identified.







Repair of Continuously Reinforced Concrete Pavement


Book Description

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.













Repair and Preventative Maintenance Procedures for Continuously Reinforced Concrete Pavement


Book Description

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.




Continuously Reinforced Concrete Pavement


Book Description

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.
