Maser and published by Strategic Highway Research Program (Shrp). This book was released on 1994 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new nondestructive, noncontact method for thickness measurement is available and can be implemented from a survey vehicle moving at highway speed. The technology incorporates horn antenna radar equipment coupled with customized processing software. This report describes an accuracy evaluation of this technology in which results from 10 Strategic Highway Research Program Long Term Pavement Performance (SHRP-LTPP) asphalt pavement sections in 10 states were compared to core data. The results were evaluated and reported in two steps--blind and calibrated.

Subcommittee D-4 on Road and Paving Materials and published by ASTM International. This book was released on 1994 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proceedings of June 1993 international symposium held in Atlanta, Georgia, called specifically to develop and standardized evaluation procedures for non-destructive methods of testing pavements. The 29 papers discuss analytical models and techniques, measurement and calculation techniques in the field and laboratory, problems and errors associated with backcalculation methods and design parameters, and testing for other pavement uses. Also includes a history of the quest for a standard and the status of that effort. Reproduced from typescripts. Annotation copyright by Book News, Inc., Portland, OR

Download or read book Ground Penetrating Radar for Evaluating Subsurface Conditions for Transportation Facilities written by Rexford M. Morey and published by Transportation Research Board. This book was released on 1998 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to state Department of Transportation (DOT) geotechnical, bridge, and pavement engineers, engineering geologists, consultants involved with ground penetrating radar (GPR) investigations for state DOTs, and researchers. It describes the current state of the practice of using GPR for evaluating subsurface conditions for transportation facilities. This was accomplished by conducting a literature search and review and an extensive survey of U.S. and Canadian transportation agencies and practitioners, as well as limited international information collection. GPR is a noninvasive nondestructive tool used in transportation applications such as evaluation and characterization of pavement systems, soils, and environmental problems. This report of the Transportation Research Board presents information on the principles, equipment, logistics, applications, and limitations of GPR pertaining to transportation applications. Selected case studies for which ground truth information is available are presented. In addition, an extensive bibliography and glossary are provided as well as appending information about GPR manufacturers from their literature.

Available in PDF, EPUB and Kindle. Book excerpt: The research project objective was to develop an implementation strategy for the use of Ground Penetrating Radar (GPR) technology to address pavement systems and underground utilities. The project was divided into three tasks. Task 1 dealt with a review in the state-of-the-art in technology, relevant applications, and regulations in the use of GPR. Task 2 discussed the effort and results of GPR survey projects on pavements systems and underground utilities that were performed as part of this project in selected locations. Task 3 developed an implementation strategy for NYSDOT for defining and procuring GPR services in addressing problems in pavement systems and mapping & locating underground utilities.

This book was released on 2020-06-16 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radar-related technology is mainly processed within the time and frequency domains but, at the same time, is a multi-dimensional integrated system including a spatial domain for transmitting and receiving electromagnetic waves. As a result of the enormous technological advancements of the pioneers actively discussed in this book, research and development in multi-dimensional undeveloped areas is expected to continue. This book contains state-of-the-art work that should guide your research.

Available in PDF, EPUB and Kindle. Book excerpt: This report will describe the various kinds of information that can be obtained from roads and highways with Ground Penetrating Radar. In the last 5 years, attention has focused on measuring the thickness of the asphalt surfacing layer on flexible pavements with air-launched horn antennas. Other antennas are available with substantially different depths of penetration, and for use in a wide range of other pavement applications. The purpose of this report is to describe the range of applications of GPR in pavement evaluation. Cases include subgrade investigations, bedrock evaluations, locating sinkholes, detecting frost damage, and identifying defects such as stripping or voids and monitoring crack growth within the pavement structure. The large variety of cases, conducted in Texas and Finland, illustrates the unique ability of GPR to rapidly evaluate subsurface conditions. The sinkhole detection study represents our initial effort to use low frequency deep penetrating radar on Texas pavements. A unique feature of this paper is the proposed classification of the frost susceptibility of subgrade soils by their measured dielectric constant and electrical conductivity.
