19.5 Pavement Deflection Data Exchange (DDX)
This format is similar to the “System.INI” in Windows. The file is divided into sections each
having a bracketed header line. The data is composed of a descriptive name, an equal sign
followed by the value(s), like: Operator = John Johnson. For details see:
TUTUwww.normas.com/AASHTO/pages/PDDX.htmlUUTT.
The following shows the beginning of a DDX data file.
