Book Description
An evaluation of NDT equipment and acquisition of a Falling Weight Deflectometer (FWD) for the Illinois Department of Transportation was accomplished. This was followed by an extensive testing program using the FWD to evaluate concrete pavements in Illinois. Test results were evaluated and procedures developed for testing and evaluation of jointed and continuously reinforced concrete pavements. Results show that some causes of incipient distresses can be detected using the FWD device including subgrade strength, loss of load transfer and development of voids. Recommendations for rehabilitations are presented in the final report.

Book Description
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

Book Description
This report documents and presents the results of a study that evaluated currently available nondestructive testing systems that appeared to have potential for supplementing or replacing coring in determining concrete pavement thickness and reinforcement location. The evaluation was done primarily in the field. The principal work consisted of the systems under on-the-job conditions on eight paving projects in six states. The measurement technique were employed in conjunction with statistical acceptance criteria evolved in the course of the study.

Book Description
This book gives information on non destructive techniques for assessment of concrete structures. It synthesizes the best of international knowledge about what techniques can be used for assessing material properties (strength) and structural properties (geometry, defects...). It describes how the techniques can be used so as to answer a series of usual questions, highlighting their capabilities and limits, and providing advices for a better use of techniques. It also focuses on possible combinations of techniques so as to improve the assessment. It is based on many illustrative examples and give in each case references to standards and guidelines.

Book Description
Three nondestructive evaluation (NDE) methods for concrete pavements--surface ultrasonic pulse velocity measurements (UPV), the impact-echo (IE) method, and the use of a seismic pavement analyzer (SPA)--were tested on six sections of two continuously reinforced concrete pavements. The results were compared with the actual condition of the concrete as determined by visual inspection, photographic imaging, and examination of cores extracted from the sections. The IE and surface UPV methods were the best in indicating the existence of macroscopic cracks. However, each must be used over a relatively long period of time to determine the deterioration rate of pavement. In addition, to be practical and efficient for application in pavement inspection, mechanization of the instrumentation of each method would be required. Even though the SPA did not compare favorably with the IE and surface UPV methods in detecting cracks and delaminations, it provided information that could be used to derive the overall qualitative condition of each test section. The results with the SPA had a high correlation with a petrographically determined rating for alkali-silica reactivity. This correlation, if verified, can serve as the basis for using the inspection system to collect information that may be used to predict the future condition of a pavement. In comparison with the other methods, the SPA would require the least additional development to be an effective inspection method. Photographic imaging was extremely valuable. Although it did not probe into the concrete as did the three NDE methods/systems investigated, it captured the surface cracks and other surface features that may well be useful indicators of the future condition of the pavements. In view of the recent advancements in the technology of high-resolution digital imaging systems and computers that can make this inspection method quantitative, which it seriously needs to be, photographic imaging deserves attention as an NDE method.
