Book Description
Extensive field, laboratory and analytical studies were conducted into the evaluation and rehabilitation of concrete pavements. Field studies included over 350 rehabilitated pavement sections throughout the US and the construction of two field experiments. A laboratory study was conducted on anchoring dowels in full-depth repairs. Analyses of field and laboratory data identified performance characteristics, improved design and construction procedures, and provided deterioration models for rehabilitated pavements. A concrete pavement advisory system was developed to assist engineers in project level evaluation and rehabilitation.
Evaluation of Jointed Reinforced Concrete Pavement Rehabilitation on I-64 in the Richmond and Hampton Roads Districts of Virginia

Book Description
Beginning in 2004, the Virginia Department of Transportation (VDOT) undertook a series of pavement rehabilitation projects to address deficiencies in three sections of the I-64 corridor between Richmond and Newport News. I-64 serves as the primary avenue between the Richmond and Hampton Roads metropolitan areas and carries a combined traffic volume ranging from approximately 20,000 to 90,000 vehicles per day. For nearly 100 mi, this roadway is a four-lane divided facility that was originally built between the late 1960s and early 1970s as either a jointed reinforced or continuously reinforced concrete pavement. The existing concrete pavement was rehabilitated using three rehabilitation procedures: two standard approaches and an experimental approach. The standard rehabilitation procedures included the use of full-depth portland cement concrete (PCC) patches overlaid by a hot-mix asphalt (HMA) overlay and full-depth PCC patches followed by grinding of the pavement surface. The experimental rehabilitation procedure consisted of the use of full- and partial-depth HMA patches followed by an HMA overlay. The purpose of this study was to document the initial condition and performance to date of the I-64 project and to summarize similar work performed by state departments of transportation other than VDOT. The pavement rehabilitation cost per lane-mile was nearly 20% less for the section of I-64 for which full-depth PCC patches followed by grinding of the pavement surface was used than for the other two sections. However, the experimental results do not allow for a comparison to determine any differences in the structural capacity or service life between the sections. The study recommends that VDOT's Materials Division annually monitor the ride quality of the pavement in the three rehabilitated sections of I-64 so that the end of service life can be defined as the pavement roughness increases because of deterioration. Further, the Virginia Transportation Research Council should collaborate with other research organizations to encourage and pursue full-scale or laboratory-scale accelerated pavement testing to determine the optimum repair materials and methods for pre-overlay repair of existing PCC pavements and to develop models to quantify the deterioration of an asphalt overlay placed over an existing concrete pavement because of reflection cracking.

Book Description
The Specific Pavement Studies 6 (SPS-6) experiment, "Rehabilitation of Jointed Portland Cement Concrete Pavements," was designed as a controlled field experiment that focuses on the study of specific rehabilitation design features of jointed plain concrete pavements (JPCP) and jointed reinforced concrete pavements (JRCP). This experiment examines the effects of climatic regions (wet-freeze, wet-no freeze, dry-freeze, or dry-no freeze), type of concrete pavement (plain or reinforced), condition of existing pavement prior to rehabilitation (fair or poor), and traffic rate (as a covariant), incorporating the different methods of rehabilitation with and without asphalt concrete (AC) overlays. This report documents the first comprehensive review and evaluation of the SPS-6 experiment.

Pages : 96
Book Description
The state of the art of Portland cement concrete pavement evaluation is reviewed with emphasis on the methods applicable to the urban freeway environment. Methods are recommended for texture evaluation, void detection and condition surveys. Data analysis methods useful for the development of pavement performance models are presented. The overall framework for life cycle cost (LCC) analysis is described with recommendations for the development of a LCC method for the Arizona Department of Transportation.
Rehabilitation of Asphalt-overlaid Concrete Pavements

Book Description
More than 60% of Illinois' Interstate concrete pavements have already been overlaid with asphalt, and by some estimates nearly 100% of Illinois' Interstate system (excluding recently constructed and reconstructed sections) are expected to have been overlaid at least once by the year 2000. Evaluation and rehabilitation of asphalt-overlaid concrete (AC/PCC) pavements have therefore become increasingly prominent and pressing concerns. Project IHR-532 is a cooperative research study between the Illinois Department of Transportation and the University of Illinois entitled "Rehabilitation of Asphalt-Overlaid Concrete Pavements". The objective of this study is to develop practical guidelines for evaluation and rehabilitation of AC/PCC pavements. These guidelines have been developed and presented in five reports which encompass AC/PCC pavement deterioration and survival, evaluation, rehabilitation, and selected case studies. This final report presents a summary of these guidelines.
