What does “nano-technology” mean? What are the problems we need to solve in a South African context? Prof Jordaan takes us from the basics of road pavement engineering and the mind shift required to move from conservative and expensive methodologies to exploring “new-age” nanotechnologies. This detailed presentation covers everything from current material design practices to recommendations for efficient and cost effective alternatives, together with project examples.
