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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.

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.

This book was released on 2007 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the properties of two high performance concrete (HPC) paving projects in Virginia. These continuously reinforced concrete pavements were placed on State Route 288 near Richmond and on the U.S. 29 Madison Heights Bypass in Lynchburg; a minimum flexural strength of 650 psi at 28 days was required for each. In an attempt to control cracking, reduced shrinkage was sought through the use of large maximum size well-graded aggregates and proper curing. The results showed that satisfactory strengths can be obtained at 28 days. Concretes with the lowest water content had the lowest shrinkage, as expected. For desired performance, good construction practices including a level base, correct steel placement, proper consolidation, timely texturing, and effective curing are required. Although pavement designs are based on flexural strength, compressive strength tests are more convenient and less variable than are flexural strength tests. Therefore, a correlation was established between flexural and compressive strength, and acceptance of the pavements was based on compressive strength. The findings of the study led to the following recommendations with regard to the concrete used in HPC paving projects: Consider specifying strength at ages above 28 days to encourage the use of a higher percentage of pozzolanic material; specify the use of large maximum size aggregate in combination with well-graded aggregate to reduce water content and minimize segregation; use trial batches to determine the minimum cementitious materials content that provides acceptable strength and workability; use actual elastic modulus values to check and adjust the design of the pavement; use a test section before the start of the paving operation to determine if any changes to the equipment and placement procedures are needed; use compressive strength for the acceptance of a project after a correlation with flexural strength is established; permit maturity testing to estimate the strength of concrete in the pavement for opening to traffic based on concrete curing time and temperature. If as little as a 10 percent increase in service life were achieved by using HPC, the savings would be in the millions of dollars over the life of the pavement. With proper selection of the aggregates, a reduction in the cementitious material content of 50 lb/yd3 is possible and would translate to a savings of about $400,000 dollars for the two projects investigated in this study. The reduction in time for opening to traffic of new or reconstructed pavements through strength estimation by the maturity method and the use of appropriate earlier strength mixtures can lead to road user cost savings close to $0.5 million per year.

This book was released on 2019 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2016, the Virginia Department of Transportation (VDOT) executed a contract to reconstruct portions of Terminal Boulevard (SR 406) in Norfolk. The work consisted of rubblizing the existing continuously reinforced concrete pavement and placing 6 in of asphalt mixture on top of the compacted rubblized concrete material. The project limits were from the I-564 loop ramp to the intersection with Hampton Boulevard in the westbound direction and from the intersection with Hampton Boulevard to the bridge over the railroad tracks in the eastbound direction. The purpose of this study was to document the current condition of the rubblized and reconstructed pavement on Terminal Boulevard (SR 406) and to generate baseline pavement performance information. Laboratory tests indicated that the asphalt mixtures used were expected to be rut resistant and resistant to non-load related cracking. Field tests using a falling weight deflectometer showed that the pavement section is structurally strong with a low deflection. AASHTOWare Pavement ME software showed a design life of 18 to 19 years for the pavement in terms of bottom-up fatigue cracking. The analysis also predicted higher rutting than expected. VDOT pavement management data showed an increase in roughness and rutting between 2017 and 2018, but the difference could be attributable to random variation from year-to-year testing. The study recommends that the Virginia Transportation Research Council continue to monitor the performance of the rubblized pavement on SR 406 and report on its condition in approximately 3 and 5 years. Any lessons learned during this time should be submitted to VDOT’s Hampton Roads District and VDOT’s Materials Division for review.

This book was released on 2011 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transportation authorities need tools to characterize the structural conditions of jointed concrete pavements (JCPs) to minimize or, in the best case, prevent premature failures of rehabilitated JCPs. Applications of the rolling dynamic deflectometer (RDD) and ground penetrating radar (GPR) in pavement forensic studies and rehabilitation investigations are presented. The continuous RDD deflection profiles allow the evaluation of mid-slab behavior and load transfer conditions of joints/cracks, while GPR surveys assist in detecting adverse subsurface conditions such as voids and increased moisture. In this paper, the patterns in RDD deflection profiles that represent the four different structural conditions in JCPs are presented and discussed. Then, the results from combined RDD and GPR surveys on two rehabilitation projects are presented. In the first project, the problematic slabs with poor load transfer and high vertical differential deflections are identified in the RDD profile. The GPR survey is used to identify the cause of the high differential deflections, voids filled with water under the slabs. The recommendation is to fill the existing voids by using under-sealing techniques and install dowel-bar retrofit prior to a new overlay. In the Grogans Mill project, the RDD profile shows that the southbound lane has a significant number of slabs with a strong potential for reflective cracking. The GPR data indicated that there is moisture beneath the deteriorated slabs. A reconstruction of the southbound lane is recommended. On the other hand, the northbound lane consists of three subsections that require different rehabilitations: Slab replacement, asphalt overlay, and reconstruction. The success of rehabilitation generally depends on the selection of appropriate treatments. By providing 100 % coverage, both RDD and GPR are effective tools in evaluating existing conditions, and the combination of these tools significantly assists in selecting the optimum rehabilitation treatment.
