Geology and petrology of road construction materials revisited; paper presented at 13th ARCSMGE conference in Marrakech, Morocco, December 2003

Abstract

As the need for road construction materials increased with urban and rural development, their availability is decreasing. They are becoming more costly, their extraction usually has serious environmental implications and many of the most suitable materials have been depleted. Significant work on the engineering petrology of construction materials was carried out in South Africa in the late 1960s but this has not been continued and reported on an ongoing basis and subsequent problem materials have not been described or reported in a single document.
