Dr Maxwell Gordon Lay is a widely recognised expert in both road technology and road history. His Handbook of Road Technology is now in its fourth international edition, and his world history of roads, Ways of the World, has been a major work in this field for two decades. In 2005, Lay was appointed a Member of the Order of Australia, for service to engineering, particularly through leadership in the delivery of quality road infrastructure and the development of new contract management processes, and as an educator and historian. In 2000, the Australian Road Research Board named its library the “M. G. Lay Library” to honour “his passion for the dissemination of high quality professional information.” In 2014, Lay was awarded the Peter Nicol Russell Medal, the highest award offered by the Australian engineering profession. He has written over 760 books, book chapters, papers and reports, and has had terms as President of the Australian Automobile Association, the Royal Automobile Club of Victoria and the Royal Society of Victoria.
