Collection and Interpretation of Pavement Structural Parameters Using Deflection Testing – part 2

March 2013

Pavement deflection testing is undertaken as the primary means for establishing structural parameters. Part I of this set of two reports discusses “Network Level” deflection testing for asset
management purposes.

This report, Part II, addresses “Project Level” testing and interpretation for rehabilitation treatment of specific road lengths, or quality control during construction.

Typical parameters established from deflection testing on New Zealand roads, including the NZ Transport Agency’s (NZTA) Long Term Pavement Performance (LTPP) benchmark sites, are presented.
