Using RLT (Repeated Load Triaxial) test data for granular materials in CIRCLY Pavement Design

RLT (Repeated Load Triaxial) tests are used in New Zealand to characterize the rutting resistance of granular materials (NZ Transport Agency T15 (2014)).

You can use properties from RLT tests in CIRCLY via the Unbound Granular RLT (Austroads 2004 sub-layering) material type.

These notes outline the steps in CIRCLY.
