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.

Book Synopsis Using Nondestructive Testing Technologies to Assist in Selecting the Optimal Pavement Rehabilitation Strategy by : DH. Chen

This book was released on 2007 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive evaluation of pavement condition and an understanding of the underlying causes of pavement distress is vital in selecting the optimal rehabilitation strategy. Three projects were investigated in this study to demonstrate the application of nondestructive testing technologies in this election process. Ground Penetrating Radar (GPR), Falling Weight Deflectometer(FWD), and Dynamic Cone Penetrometers (DCP) were successfully used on these TxDOT projects. GPR was employed successfully to locate defects in the hot mix surface layer that were responsible for the chronic distress on US 69.This roadway was rehabilitated previously but the strategy used had not addressed the root cause of the pavement problem. FWD and DCP data were also used to determine the structural capacity or layer moduli of the pavement system that allows the designer to derive the overlay thickness. Coring and trenching were utilized to verify the defects detected in the GPR data. The advantage of nondestructive testing is that it provides a comprehensive evaluation of sub surface conditions throughout the entire project, not only at locations where coring and trenching are performed. Furthermore, GPR was employed to verify a rehab design of an old JCP pavement on SH 73. Originally, the plan called for pressure grouting to fill the subsurface voids. However, GPR found no voids under the JCP slab; this was validated in subsequent coring. Therefore the GPR results helped district personnel to eliminate the cost of the pressure grouting. For comparison purposes, GPR results from IH 45 and US 82 (where there were voids under JCP slabs) were utilized.

Book Synopsis Integrating Ground Penetrating Radar and Falling Weight Deflectometer Technologies in Pavement Evaluation by : T. Scullion
Download or read book Integrating Ground Penetrating Radar and Falling Weight Deflectometer Technologies in Pavement Evaluation written by T. Scullion and published by . This book was released on 2000 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first step in selecting the optimal rehabilitation strategy for any pavement is to identify the cause of the existing defects. In recent years nondestructive technologies such as Falling Weight Deflectometers and Ground Penetrating Radar have been used to evaluate subsurface conditions. However when used independently these technologies are not always adequate for identifying the cause of pavement deterioration. This paper will present the argument for developing an integrated approach to pavement evaluation wherein the high speed GPR survey results can be used to identify homogenous sections, locate potential subsurface defects and estimate layer thicknesses. The GPR then provides critical inputs to both the processing of the FWD data and the interpretation of the results.

This book was released on 2014 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unlike discrete testing methods, the rolling dynamic deflectometer (RDD) performs continuous measurements. Thus, it is a powerful screening and evaluation tool for quickly characterizing large sections of highway and airfield pavements with little danger of missing critical pavement features. RDD testing applications have involved (1) pavement forensic investigations, (2) delineations of areas to be repaired, (3) selections of rehabilitation treatments, measurements of relative improvements due to the rehabilitation, and (4) monitoring of changes with time (trafficking and environmental loading). This paper discusses the efforts to improve the velocity of RDD testing up to 5 mph (8.0 km/h) while minimizing the accuracy and resolution of deflection data. The research consisted of the development of a velocity-improved rolling sensor and the field evaluation of its new sensor system. The velocity-improved rolling sensor and the enhanced data processing were tested in both flexible and rigid pavements at varied velocities. The enhanced RDD system potentially enabled testing velocities of up to 5 mph (8.0 km/h) in thin flexible pavements (i.e., farm-to-market roads) and up to 3 mph (4.8 km/h) in rigid pavements.
