Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this Federal Highway Administration Demonstration Project was to evaluate the installation and performance of a section of I-81 in Botetourt County, Virginia, that was rehabilitated by concrete pavement restoration (CPR) methods. The seven repair techniques used were (1) slab replacement, (2) patching, (3) slab stabilization (4) surface grinding, (5) joint resealing, (6) subdrain installation, and (7) load transfer restoration. Although the individual repair techniques had varying degrees of success, CPR as an integrated system was generally effective in restoring the pavement's structural and functional integrity. It was recommended that the Virginia Department of Transportation routinely consider CPR as a viable alternative for pavement rehabilitation. It was also recommended that projects under consideration for restoration be carefully evaluated to ascertain whether their structural conditions render them suitable for CPR.

Diefenderfer and published by . This book was released on 2009 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis A Pavement Management System for Concrete Roadways in Virginia by : Robert R. Long
Download or read book A Pavement Management System for Concrete Roadways in Virginia written by Robert R. Long and published by . This book was released on 1988 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report traces the development of a rating system proposed by the author and reviewed by a subcommittee of the Pavement Management Research Advisory Committee for use in evaluating the service condition of Virginia's Portland cement concrete pavements. The service condition is assessed in terms of distress roughness, i.e., that portion of a pavement's poor ride characteristics directly attributable to the occurrence of certain key distress types. The key distresses identified for jointed concrete pavements are permanent patching, lane/shoulder separation, transverse joint faulting, transverse joint seal damage, and scaling, map cracking, or crazing. For continuously reinforced pavements, spacing of transverse cracks, lane/shoulder separation, and scaling, map cracking, or crazing were identified. Field surveys of the occurrence of these distresses provided the necessary data for estimating distress roughness through the use of prediction equations that have been established from the standard statistical analysis of pavement section distress data and roughness measurements. The use of distress roughness to reflect a pavement's service condition provides a common basis for comparison of pavement sections. This, in turn, enables managers to set priorities for pavement rehabilitation. These rating procedures and a comprehensive system for managing Portland cement concrete pavements will be implemented in a subsequent project.

Book Synopsis Evaluation of a Thin-bonded Portland Cement Concrete Pavement Overlay by : Thomas Elliott Freeman
Download or read book Evaluation of a Thin-bonded Portland Cement Concrete Pavement Overlay written by Thomas Elliott Freeman and published by . This book was released on 1996 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis A Case Study Evaluation of the Use of Video Technology in Concrete Pavement Evaluation by : Thomas Elliott Freeman
Download or read book A Case Study Evaluation of the Use of Video Technology in Concrete Pavement Evaluation written by Thomas Elliott Freeman and published by . This book was released on 2000 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of an evaluation of video technology as a possible solution to the problem of safely collecting objective condition data for prioritizing concrete pavement rehabilitation needs in Virginia. The study involved the evaluation of one commercially available video image distress survey system with regard to its capacity to generate objective information about concrete pavement condition. Ratings of the functional and structural condition of 1223 centerline kilometers (758 miles) of concrete-surfaced interstate and primary roadways were derived from visual examinations of the videotapes. Results of the evaluation were used as the basis for determining if sufficiently accurate condition ratings as compared to ratings resulting from direct visual examination in the field (i.e., "control" ratings) were attainable from the video survey method to support a pavement management system for concrete roadways in Virginia. Results of the distress survey derived from tape-recorded images compared poorly with those results observed directly in the field. The researcher concluded that the inconsistent quality of video images and the human error introduced during the video analysis phase were the primary causes of the discrepancies between the two rating methods. Although the researcher's assessment of this video survey system was not favorable, the study provided useful guidance on needed refinements to improve the viability of the system.

Book Synopsis Evaluation of the Installation and Initial Condition of Hydraulic Cement Concrete Overlays Placed on Three Pavements in Virginia by : Michael M. Sprinkel
Download or read book Evaluation of the Installation and Initial Condition of Hydraulic Cement Concrete Overlays Placed on Three Pavements in Virginia written by Michael M. Sprinkel and published by . This book was released on 1999 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydraulic cement concrete pavement overlays were placed in the summer of 1995 at the following locations in Virginia: I-295 near Richmond, I-85 near Petersburg, Rt. 29 near Charlottesville. Overlays were placed on I-295 SBL (near mile marker 29) and I-85 SBL (near mile marker 51) in Virginia to prevent spalling caused by a shy cover over the reinforcement and to enhance the structural integrity. Both locations are continuously reinforced concrete pavement. An overlay was also placed on Rt. 29 NBL (1.6 km south of Charlottesville) in Virginia to correct a rutted asphalt pavement. The construction was funded with 20 percent Virginia Department of Transportation maintenance funds and 80 percent special ISTEA Section 6005 federal funds specifically allocated to demonstrate overlay technologies. ISTEA funds were also used to evaluate the installation and initial conditions of the overlays and to prepare the report. The variables in this study were concrete mix design, overlay thickness, and base material. Mineral admixtures and steel and plastic fibers were used to improve the mechanical properties and durability of the overlay concrete. Overlay thickness and base material were varied to determine their effect on overlay performance.
Book Synopsis Assessment of Composite Pavement in Virginia by : M. Shabbir Hossain

Available in PDF, EPUB and Kindle. Book excerpt: The Strategic Highway Research Program 2 (SHRP2) identified composite pavement as a “renewal solution” to support for implementation, and the Virginia Department of Transportation (VDOT) received funding to demonstrate its potential. In 2017, this funding was applied to support major rehabilitation of two westbound lanes of US 60 in Henrico County, Virginia, a project that essentially replaced 1.1 miles of deteriorated concrete pavement with a new composite system consisting of continuously reinforced concrete pavement (CRCP) overlaid with stone matrix asphalt (SMA). This new composite pavement was designed in accordance with the 1993 AASHTO Guide for Design of Pavement Structures and was constructed in accordance with VDOT specifications and standards existing at the time. During construction, material properties were characterized to enable mechanistic-empirical (ME) analysis, and AASHTOWare Pavement ME Design software was then used to analyze the pavement again using the “asphalt concrete overlay over CRCP” option as suggested in the SHRP2 research. Because of the low truck traffic count on US 60, the predicted distresses for a 30-year design life were found to be very low compared to an analysis that uses the Pavement ME Design software default criteria. Through-the-thickness temperature changes were also monitored and it was found that the asphalt overlay provides an insulating effect for the underlying concrete, hence reducing the curling and thermal stresses in the concrete pavement. SHRP2 researchers suggested that the thickness of the concrete portion of a composite pavement could usually be 1 to 3 in less than that of a plain (bare) concrete for comparable performance. Similar trends were observed for a higher truck traffic scenario in this study when a composite pavement (CRCP overlaid with SMA) was analyzed using the Pavement ME Design software. VDOT maintains more than 500 lane-miles of CRCP that has been overlaid with asphalt at an average age of 26 years. These pavements, now considered “composite” pavements, are still in service, often after multiple asphalt mill and replace operations, with some as old as 52 years. The average life of these overlays is 10 to 15 years, with the combination of CRCP and SMA often providing 16 to 23 years per cycle. The main distress mechanisms in a composite pavement are reflective cracking and rutting. The natural cracking and rut resistance of SMA therefore make it an ideal option for the asphalt component of a composite system. Such a design will protect the concrete base before any distresses have developed while also moderating thermal stresses (the insulating effect). The prospects for superior long-term service with low maintenance costs are excellent.

This book was released on 2004 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A two-lane continuously reinforced concrete pavement was built in Blacksburg, Virginia, as a part of Virginia's Smart Road. One of the lanes is 12 ft wide, and the other is 14 ft wide. The additional 2 ft was part of the shoulder. Below the concrete pavement is a 3-in-thick open-graded drainage layer (OGDL); one section is asphalt stabilized, and the other section is cement stabilized. The concrete pavement was cured by a curing compound except that the 12-ft lane was also covered with plastic and straw because of concerns with cold ambient temperature. The objective of this project was to determine the material properties of the concrete, instrument the pavement, monitor construction practices, and monitor the performance of the pavement over 4 years. The concrete had high early strength, low permeability, and high shrinkage. The average crack spacing was more than 3 ft, indicating satisfactory performance. In general, cracks were wider when they were further apart, but the differences in crack spacing and width were variable and small in some cases and could not be correlated after 4 years. The end sections had less cracking than the interior sections of the pavement. There were fewer cracks and more space between cracks in the 12-ft lane and fewer cracks in the pavement over the asphalt-stabilized OGDL. This was attributed to a better cure in the 12-ft lane and to a lower friction over the asphalt-stabilized base. No changes to the specifications were recommended as a result of the study findings.
