Book Description
This TechBrief describes both conventional methods and an alternative method for making full-depth repairs in continuously reinforced concrete pavements. The alternative method, which does not utilize continuous longitudinal reinforcement in the repair area, is suitable for repairing a single lane (or two of three adjacent lanes), and results in repair areas that have performed well after several years.

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.

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.

Book Description
Considerable efforts and money are spent to maintain and repair the distressed jointed concrete pavement (JCP) sections by providing partial-/full-depth repair, under sealing, and patching; however, a lot of distresses reoccur frequently. For severe distresses, overlay was constructed on the JCP. Resurfacing with a bonded concrete overlay (BCO) over the existing pavement to form a monolithic structure has proven to be a cost-effective rehabilitation strategy. Continuously reinforced concrete pavement (CRCP) bonded overlay was constructed for the rehabilitation of a 2000 ft long JCP section on U.S.75 in Sherman, Texas, United States which had been subjected to numerous rehabilitations to construct the guidelines of the CRCP bonded overlay. The pavement design and concrete mix design selected are discussed and introduced in this article. In order to reduce the reflective cracking at the location of the JCP joints, geotextile was placed at the joint location before the overlay construction. For the study on the function of the geotextile, the geotextile was not placed at 20 JCP joints for the comparison. One week after the BCO construction, the investigation for the CRCP cracking was carried out at three stages. The investigated results revealed that the cracks at the transverse steel location are much more than those between the transverse steel. Falling weight deflectometer testing was run on the pavement surface before and after the overlay construction to measure the deflection behavior of the pavement. The performance of the overlay shows that the bonded CRCP is appropriate for the JCP resurfacing.

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.
