Recycled Materials in Geotechnical and Pavement Applications

<p>This book considers the application of recycled materials both in pavement and geotechnical engineering. Currently Australia has faced the fundamental concern of recycling waste plastic. On 1 January 2018 China enforced a prohibition on the importation of waste plastic. China's ban is followed by other countries like India Indonesia and Malaysia. The ban caused many corporations to abandon waste collection agreements and the stockpiling of waste as there is nowhere to safely deposit this waste. This issue seems to a great extent to have placed Australia's recycling industry in a crisis. As a result local councils will have to find strategic ways of recycling accumulated waste that will become a more significant issue in the coming years. In Australia apart from economic growth the road pavement has weakened rapidly as the current pavement unable to withstand this urgent traffic load demand. The adding of polymers to the mixtures improves the stiffness rutting resistanceand fatigue cracking [1]. However the application of virgin polymer is costly. Thus using waste polymer such as waste plastic polymer is an inexpensive substitute. The potential for recycled plastic to improve the performance properties of asphalt mixtures has been demonstrated in many countries the UK Canada The Netherlands and India [2]. Similarly another application of recycled materials can be in geotechnical infrastructure. This book considers the application of recycled materials both in pavement and geotechnical engineering.</p><p>References </p><p>[1] Airey G.D. Singleton T.M. & Collop A.C.(2002).
