Adelaide AirportRunway Extension

Richard Cavagnaro and Roger Grounds

This project involved the diversion of Tapley’s Hill Rd and the extension of the main runway of Adelaide airport to allow fully loaded 747 jets to take off and land. Discussed were: the site investigation techniques used and the test results obtained with particular emphasis on the very soft soils encountered in the bed of the Patawalonga creek, the pre-load testing conducted in the grounds of the airport; and the excavation and filling techniques employed.
