Book Description
Information was collected from each of the six states in Region 5 of the Federal Highway Administration (FHWA) on the procedures used to rehabilitate jointed concrete pavements. As built plans and specifications were obtained from a number of projects in each of the six states which had been rehabilitated and the performance of the pavements were studied after a number of years in service. Interviews were conducted with personnel of the Departments of Transportation from each state to collect as much information as possible concerning the current practices and techniques used for pavement rehabilitation. Where sufficient data were available, statistical correlations were made of the performance trends as they relate to specific rehabilitation practices. Current practices were compared with earlier practices and efforts made to determine the reasons for the changes. Results show that the performance is closely related to the workmanship in the field and the ingenuity of the engineers involved. Recommendations are presented for each of the rehabilitation techniques studied. Many problems still exist with all of the techniques studied. Further detailed data on the exact procedures and practices used in the field during the rehabilitation and performance after rehabilitation are desperately needed. Better record keeping is sorely needed on both the "as built" conditions and on the performance, so the effectiveness of the various practices can be documented.

Book Description
Load transfer restoration (LTR) is a rehabilitation technique for increasing the load transfer capability of existing jointed portland cement concrete pavement by placement of dowel bars or other mechanical devices across joints and/or cracks that exhibit poor load transfer.

Book Description
Deterioration in Portland Cement Concrete (PCC) pavements can occur due to distresses caused by a combination of traffic loads and weather conditions. Hot mix asphalt (HMA) overlay is the most commonly used rehabilitation technique for such deteriorated PCC pavements. However, the performance of these HMA overlaid pavements is hindered due to the occurrence of reflective cracking, resulting in significant reduction of pavement serviceability. Various fractured slab techniques, including rubblization, crack and seat, and break and seat are used to minimize reflective cracking by reducing the slab action. The main objective of this project is to develop a mechanistic-empirical (ME) design aproach for the HMA overlay thickness design for fractured PCC pavements. In this design procedure, failure criteria such as the tensile strain at the bottom of HMA layer and the vertical compressive strain on the surface of subgrade are used to consider HMA fatigue and subgrade rutting, respectively. The developed ME design system is also implemented in a Visual Basic computer program.

Book Description
The pavement analysis in this study considers various combinations of pavement rehabilitation treatments (two-course HMA overlay with or without surface milling, concrete pavement restoration, three-course HMA overlay with or without surface milling, three-course HMA overlay with crack and seat of PCC pavement and 3-R and 4-R overlay or replacement treatments). Six road functional classes (rural and urban of interstates, non-interstates of the NHS, and non-interstates non-NHS) are considered. This allows for estimation of the performance and service life of the pavement, corresponding to each treatment and road functional class.
