Book excerpt: "This study evaluates fiber reinforced polymer (FRP) dowel bars as load transferring devices in jointed plain concrete pavement (JPCP) under HS25 static and fatigue loads and compares their response with JPCP consisting of steel dowels. Along with laboratory and field evaluations of JPCP with FRP and steel dowels, analytical modeling of dowel response was carried out in terms of maximum bending deflection, relative deflection (RD), and bearing stress of dowels. In addition, field rehabilitation of JPCP was carried out using FRP dowels to evaluate its long-term performance"--Technical report documentation page.

Available in PDF, EPUB and Kindle. Book excerpt: The SPS-2 experiment, "Strategic Study of Structural Factors for Jointed Plain Concrete Pavements (JPCP)," is one of the key components of the Long Term Pavement Performance (LTPP) program. The main objective of this experiment is to determine the relative influence and long-term effectiveness of JPCP design features (including slab thickness, portland cement concrete flexural strength, base type and drainage, and slab width) and site conditions (traffic, subgrade type, climate) on performance. This report documents the first comprehensive review and evaluation of the SPS-2 experiment

This book was released on 2007 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this study was to develop, implement, and evaluate a Level 1 performance-related specification (PRS) for the construction of a jointed plain concrete (JPC) pavement in the State of Wisconsin. The research entailed a thorough evaluation of the construction quality levels achieved on recent Wisconsin JPC projects and the formulation of a Level 1 PRS using the results of the quality evaluation and defined Wisconsin Department of Transportation (WisDOT) pavement practices as a basis. Feedback from WisDOT and the contractor indicated that this first PRS implementation in Wisconsin was successful, particularly with respect to the layouts of lots and sublots. Several suggestions were received to improve and streamline the PRS process.

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.

This book was released on 2000 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The current performance-related specifications (PRS) methodology has been under development by the Federal Highway Administration (FHWA) for several years and has now reached a level at which it can be implemented by State highway agencies. PRS for highway pavements depend heavily on performance prediction models to determine the impact of varying levels of construction quality. This study focused on the improvement of the key distress and smoothness prediction models used in the PRS for jointed plain concrete pavement (JPCP). Performance models for transverse joint faulting, transverse slab cracking, transverse joint spalling, and smoothness (International Roughness Index [MI]) were evaluated and then improved substantially. This was accomplished using a comprehensive national database of JPCP performance data, along with sound statistical and engineering techniques. Performance model calibration guidelines were also developed so that a State cari calibrate any of these models specifically to its pavement performance data. The PaveSpec PRS demonstration software was upgraded to Version 3.0 under this study. Some of the specific improvements incorporated in PaveSpec 3.0 include: 1) incorporation ofyim proved distress indicator models, as well as the ability to calibrate or modify the default models, 2) sensitivity analysis capabilities, 3) expected pay charts, and 4) online help. Appendix A of this report contains a complete updated PaveSpec User's Guide"--Technical report documentation page

Book excerpt: Conventional construction of Jointed Plain Concrete Pavements (JPCP) in Canada consists of placing a round steel epoxy-coated dowel at the mid height of the pavement. Steel dowels reduce stepping at the joint to improve comfort and reduce the stress concentration on the support layer beneath the pavement. Most importantly they transfer load and are commonly referred to as load transfer devices. Problems with dowel bar deterioration, including corrosion causes the slab joint to lock and cause stress concentrations as the slab expands and or contracts and curls due to thermal and shrinkage straining occurring in the concrete. In this research, alternative joint load transfer devices are presented and compared to conventional steel dowels. Four device alternatives are developed and evaluated: a Glass Fibre Reinforced Polymer (GFRP) I-beam placed directly on the base material; GFRP tapered plates; a continuous horizontal V device; and a continuous horizontal pipe device both placed directly on the support layer. The two devices that are continuous run the length of the joint similar to a shear key. The GFRP tapered plate and I-beam, as well as conventional steel dowels, were analyzed in a wheel path sized three dimensional finite element model for wheel loading and static loading applied to either side of the joint. An experimental testing program was developed to test joint load transfer capabilities of each device when subjected to a static wheel load applied to either side of the joint. The GFRP tapered plates and I-beams were shown to transfer load based on the results from the wheel path finite element model and experimental testing program. The differential joint deflection, stress concentrations and plastic straining occurring in the concrete is not reduced with either the tapered plate or I-beam compared to a dowel under wheel loading. In addition, a similar plastic straining area identified in the finite element models were noticed as an area of damage in the experimental testing program. All of the devices developed are analyzed in a quarter slab three dimensional finite element model with shrinkage and thermal strains as well as wheel loading applied to the slab to simulate service loading. A detailed investigation into the stress distribution around the devices and the differential deflection at the joint through the service loading applied is presented in this paper. Similarly to the wheel path investigation the stress concentration in the tapered plate and I-beams are greater than conventional dowels and also have greater differential deflection occurring at the joint. Both the continuous Horizontal V and Horizontal Pipe device reduce stress and plastic straining in the concrete during the service load analysis compared to dowels. During daytime wheel loading the differential deflection in the joint is the lowest with no noticeable stepping occurring at the joint with the Horizontal V device; however is greater than conventional steel dowels under nighttime wheel load application. The differential deflection with the Horizontal Pipe during day and night straining and wheel loading is similar to conventional steel dowels.
