Evaluation of the Soniscope for Nondestructive Testing of Portland-cement Concrete Pavements
Author: George M. Pace
Publisher:
ISBN:
Category : Pavements, Concrete
Languages : en
Pages : 94
Book Description
The report presents the results obtained from the soniscope instrument for use in the nondestructive testing of portland-cement concrete pavements. Essentially, the instrument was tested to determine if consistent velocity measurements could be obtained with the transducers in a position vertical on the prestressed, reinforced, and plain concrete pavements. Also, of interest during the investigation was the maximum distance through portland-cement concrete for which consistent velocity measurements could be obtained. (Author).

Comparative Study of Nondestructive Pavement Testing, MacDill Air Force Base, Florida

ISBN:
Category : Nondestructive testing
Languages : en
Pages : 278
Book Description
This project is the most comprehensive single undertaking to date which is directed toward an evaluation of the validity of concepts of nondestructive evaluation of the load-carrying capacity of airfield pavements. Seven nondestructive test devices tested five sections of airfield pavements at MacDill Air Force Base (AFB) which consisted of two rigid, two flexible, and one composite pavements, ranging from 20-in. portland cement concrete (PCC) to 5.5- in. asphaltic concrete. Analytical treatments of the test data included empirical correlation analyses, and layered-elastic and finite element computer analyses. Six private firms each with a different nondestructive testing (NDT) evaluation method provided evaluation results in terms of allowable aircraft loads and overlay thicknesses. The Air Force produced one set of results using its new nondestructive pavement testing method, and Waterways Experiment Station provided three sets of results. This study has shown that NDT technology exists for evaluation of airfield pavements. For the pavements at MacDill AFB, some NDT evaluation methods agreed better with the standard test-pit method than others. However, the pavements at MacDill AFB are rather nontypical, and those NDT evaluation methods that did not give good results at MacDIll may give more agreeable results on different pavements. The lack of agreement between results of the NDT evaluation methods does justify concern and may point to the need for a standard evaluation method.

Nondestructive Testing for Light Aircraft Pavements

Book Description
Methodologies have been developed for nondestructive testing (NDT) and evaluation of air carrier airport pavements. This study, a two-phase program, addresses those pavements that are designed to support aircraft with gross weights of less than 30,000 lb. Phase I, reported herein, is to evaluate commercially available NDT devices with respect to operational characteristics, costs, transportability by cargo aircraft, accuracy, and reproducibility of measurements, and suitability for use in evaluating light aircraft pavements. The equipment evaluated included the Benkelman Beam, Dynaflect, Falling Weight Deflectometer, and Models 400, 510, and 2008 Road Raters. The WES 16-kip vibrator was used as a comparison device.

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
