Book excerpt: Magnetic imaging tomography (MIT) scanning is a nondestructive method for measuring the alignment of dowels placed at transverse joints of jointed plain concrete pavements (JPCPs). Several highway agencies across the United States have adopted specifications for dowel alignment, with many using the joint score measure. However, this measure was developed intuitively and not based on any laboratory or field tests. National Cooperative Highway Research Program (NCHRP) Report 637 provides a methodology to determine an equivalent dowel diameter measure based on dowel misalignment (Khazanovich et al. 2009). This procedure was developed from laboratory tests and with limited field validation. The relationship between dowel misalignment and the performance of JPCP is unclear, but understanding it is imperative for developing construction guidelines. This report presents results of MIT scanning data collected on Long-Term Pavement Performance (LTPP) test sections and data analysis to assess the effects of dowel misalignment on JPCP performance. As part of this study, MIT scanning was performed on 121 Specific Pavement Studies-2 and 3 General Pavement Studies-3 test sections. Dowel alignment parameters, joint score, and equivalent dowel diameter were calculated as part of the analysis. Statistical analysis was performed to determine any relationship between the joint score and cracking and between the joint score and spalling. The analysis did not indicate any definitive relationship between the joint score and cracking or the joint score and spalling within the analysis range for most States, although some effect was observed for three States. This lack of relationship does not mean severely misaligned dowels have no effect on pavement performance, particularly localized distresses. Analysis of the equivalent dowel diameter as a measure of dowel misalignment for use with AASHTOWare® Pavement ME Design software suggests that using the equivalent dowel diameter is a less-biased estimator of long-term load transfer efficiency (LTE), as modeled using AASHTOWare Pavement ME Design, than using the actual dowel diameter, suggesting a relationship between dowel misalignment and long term LTE (AASHTO 2014). However, there is considerable scatter in the LTE modeled using AASHTOWare Pavement ME Design versus actual LTE. The remaining bias and scatter suggests that the models (i.e., equivalent dowel diameter and LTE in AASHTOWare Pavement ME Design) could potentially be improved using data collected as part of this study.

Book Synopsis Guidelines for Dowel Alignment in Concrete Pavements by : Lev Khazanovich
Download or read book Guidelines for Dowel Alignment in Concrete Pavements written by Lev Khazanovich and published by Transportation Research Board National Research. This book was released on 2009 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents proposed guidelines for dowel alignment in concrete pavements. These guidelines deal with the effects of dowel misalignment on performance and the measures for reducing misalignment and its adverse effect. The report will guide pavement and construction engineers in considering dowel misalignment in pavement design and identifying measures for reducing misalignment during construction or for dealing with misaligned dowels. The information contained in the report will be of immediate interest to state engineers and others concerned with concrete pavement design and construction.

Download or read book Long-term Pavement Performance, Automated Faulting Measurement written by Mahesh Agurla and published by . This book was released on 2015 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study focused on identifying transverse joint locations on jointed plain concrete pavements using an automated joint detection algorithm and computing faulting at these locations using Long-Term Pavement Performance (LTPP) Program profile data collected by the program's high-speed inertial profilers (HSIP). This study evaluated two existing American Association of State Highway and Transportation Officials R 36-12 automated faulting measurement (AFM) models: ProVAL (Method-A) and Florida Department of Transportation (FDOT) PaveSuite (Method-B). A new LTPP AFM was developed using LTPP profile data. The LTPP AFM is an automated algorithm to identify joint locations where faulting is also computed for each joint identified to replicate the manually collected faulting data using the Georgia Faultmeter (GFM), which has been used on LTPP test sections since the program's inception. The study compared the LTPP manual faulting measurements collected using the GFM with the ProVAL AFM and the LTPP AFM using LTPP profile data. Similarly, the FDOT GFM measurements were compared with the FDOT PaveSuite AFM and the LTPP AFM using the same FDOT profile data. The initial results for six LTPP test sections show that the LTPP AFM can identify joint locations with a joint detection rate (JDR) ranging from 95 to 100 percent. ProVAL's JDR range is from 58 to 99 percent for the same six LTPP test sections. Similarly, for the one FDOT test section available, the LTPP AFM's and FDOT PaveSuite's JDRs are approximately 96 percent. This study outlines the LTPP AFM algorithm, discusses the comparison of the three AFM results, and recommends future research needs in this area.
