OPERATING CHARACTERISTICS AND USER SATISFACTION OF COMMERCIALLY AVAILABLE NDT EQUIPMENT (DISCUSSION AND CLOSURE)

The results of a recent study conducted for FHWA are presented herein. The objective of the study was to develop a ready reference that describes available nondestructive testing (NDT) devices and methods for use in designing the thickness of asphalt concrete overlays for flexible pavements. The report was developed to serve as a guide to practicing highway engineers who are considering the purchase of new equipment or developing (or modifying) overlay design procedures for flexible pavements. A conscientious effort was made to determine and evaluate factors that agencies noted as important decision criteria in selecting NDT devices. The analysis was limited to equipment currently available from commercial sources. Equipment characteristics were provided by the manufacturers. To determine user feelings concerning the NDT equipment, a questionnaire was sent to selected agencies and available literature was reviewed. Summary tables of equipment characteristics and operating capabilities are provided. Selected overlay design procedures that use NDT input were described in the report; however, in this paper only basic equipment characteristics and user comments concerning the equipment are discussed.
