Sustainable Roads Through Fit‑for‑purpose Use of Available Materials: Evaluation Tool and User Guide
  • Publication no: AP-T353-20
  • ISBN: 978-1-925854-91-6
  • Published: 11 March 2020

This guidance document aims to encourage fit‑for‑purpose use of available materials for sealed and unsealed road construction and maintenance, including renewal of low to medium level traffic roads.

A fit‑for‑purpose material has properties and performance characteristics which are directly suited to the chosen design application. The use of a fit-for-purpose material ensures budget resources are optimised over the entire life cycle of the pavement, while continuing to meet a required level of service.

Understanding what influences material performance and how to balance this with budget optimisation and level‑of‑service requirements are key to a fit-for-purpose material.
