Pavement Deflection Data Exchange: Technical Data Guide, Version 1.0

Front Cover
AASHTO, 1998 - Pavements - 56 pages
Nondestructive deflection testing (NDT) devices have become integral tools in the evaluation and analysis of pavement facilities. Historically, the data produced by deflection devices have been stored in output files with the type, extent, and organization of collected data being left to the discretion of the individual equipment manufacturers. This document describes a device-independent universal pavement deflection data exchange (PDDX) specification that utilizes the data management concept of section blocks, similar to the software initialization file format used by many computer operating systems. The use of section blocks has proven to be an efficient and flexible method in the management of data and can be applied successfully to pavement deflection testing technology.
