Description

Prepared by Austroads, the guidelines outline a 7-step process for estimating pavement strength parameters, starting from a decision that network level strength information is needed.

Network level pavement strength parameters are estimated primarily from measurements of surface deflection using standard loading and other standard test procedure details. The guidelines describe the estimation from surface deflection data of Modified Structural Number (SNC) and Adjusted Structural Number (SNP) as the most commonly used network level pavement strength parameters.
