This report discusses the performance of the Virginia Department of Transportation's first modern rehabilitation project involving a thin-bonded portland cement concrete overlay of an existing jointed concrete pavement. The performance of the rigid overlay, which was constructed in a fast-track mode to minimize lane closure time, was evaluated by detailed condition surveys conducted annually throughout a 6-year analysis period to identify, document, and monitor the occurrence of distress. The roughness of the overlay was also measured annually with an accelerometer-based inertial road profiler to permit an examination of the effects of surface deterioration on ride quality. After 6 full years of service, which included only minimal maintenance, the pavement overlay remained in good overall condition. Although the ride quality of the overlay remained virtually unchanged throughout the period, a significant increase in the occurrence of low-to-moderate-severity joint spalls, corner breaks, and to a lesser extent transverse cracks was noted during the fifth and sixth years. The extrusion of compression seals and the subsequent infiltration of water into the pavement structure probably contributed to the observed localized failure of the overlay/substrate bond in the vicinity of joints. This condition, in turn, weakened the pavement's structural capacity at panel edges and thereby resulted in the formation of corner breaks and cracks parallel with and near transverse joints. The consideration of thin-bonded concrete overlays constructed in a fast-track mode is recommended as a viable rehabilitation alternative for jointed concrete pavements that are not severely distressed. However, careful attention to joint installation and, in particular, joint maintenance is recommended for similar future rehabilitation projects.

The report describes the Virginia Department of Transportations' first modern experience with the construction of thin-bonded Portland cement concrete overlays of existing concrete pavements and with the fast track mode of rigid paving. The study was conducted in cooperation with the Federal Highway Administration (FHWA) and used a paving mixture verified in an FHWA mobile laboratory. The study showed that the fast track mode will permit lane closure times as short as 48 hours. Of special interest was the finding that adequate strength of the bond between the old pavement and the overlay is not dependent on the use of a bonding grout.

The Iowa ultra-thin project demonstrated the application of thin portland cement concrete overlays as a rehabilitation technique. It combined the variables of base preparation, overlay thickness, slab size, and fiber enhancement into a series of test sections over a 7.2-mile length. This report identifies the performance of the overlays in terms of deflection reduction, reduced cracking, and improved bonding between the portland cement concrete (PCC) and asphalt cement concrete (ACC) base layers. The original research project was designed to evaluate the variables over a 5-year period of time. A second project provided the opportunity to test overlay rehabilitation techniques and continue measurement of the original overlay performance for 5 additional years.

The Iowa road system has approximately 13,000 miles of Portland Cement Concrete Pavements, many of which are reaching the stage where major rehabilitation is required. Age, greater than anticipated traffic, heavier loads and deterioration related to coarse aggregate in the original pavement are some of the reasons that these pavements have reached this level of distress. One method utilized to rehabilitate distressed or underdesigned PCC pavements is the thin bonded Portland Cement Concrete overlay. Since the introduction of thin bonded overlays on highway pavements in 1973, the concrete paving industry has made progress in reducing the construction costs of this rehabilitation technique. With the advent of the shotblast machine, surface preparation costs have decreased from over $4.00 per square yard to most recently $1.42 per square yard. Other construction costs, including placement, grouting and sawing, have also declined. With each project, knowledge and efficiency have improved.

The objective of this research was to investigate the interface bonding condition between an ultra-thin PCC overlay and an ACC base over time, considering the previously mentioned variables. This research lasted for five years, at which time it was extended an additional five years. The new phase of the project was initiated by removing cracked panels existing in the 2-inch thick PCC sections and replacing them with three inches of PCC. The project extension (TR 432) will provide an increased understanding of slab bonding conditions over a longer period, as well as knowledge regarding the behavior of the newly rehabilitated areas.

Ultra-Thin Whitetopping (UTW) is a pavement rehabilitation technique that involves the placement of a thin Portland Cement Concrete (PCC) overlay, 2 inches (50 mm) to 4 inches (100 mm) thick, over a distressed Hot Mix Asphalt (HMA) pavement. Typically, the HMA pavement is milled and cleaned which helps to create a bond between the existing HMA pavement and the PCC overlay. The bond between the two layers promotes composite action of the pavement section and as a result has a direct impact on the performance of the UTW Pavement. This composite action allows for the reduced thickness in the UTW layer. Additionally, a short joint spacing is typically used, which reduces the UTW flexural and curling stresses. In this study three different test areas were constructed in the INDOT/Purdue University Accelerated Pavement Testing facility. Each test area had different lanes that varied by concrete mix design, bonding preparation, and pavement crosssection. These sections were subjected to 300,000 to 560,000 load applications. An additional test area was constructed outside the facility to evaluate pavement thicknesses and environmental effects. The project resulted in a modified UTW design methodology that takes into account the stiffness of all underlying pavement layers. Additionally, the project provides insight into the effects of pavement section, UTW mix design, mechanical loading, bond conditions, and environmental loading on the performance of UTW.

A major field study and evaluation has been conducted into the effectiveness of three structural overlay types for portland cement concrete (PCC) pavements. These include sawing and sealing asphalt concrete (AC) overlays of PCC pavements, cracking and seating PCC pavements prior to AC overlay, and constructing a thin bonded PCC overlay on top of the existing PCC pavement. Condition surveys, deflection testing, and roughness measurements were performed on a total of 55 sections. The performance of these sections was evaluated and the effectiveness of each overlay type analyzed.
