Valorisation of Waste and Secondary Materials for Roads State-of-the-Art Report of the RILEM TC 279-WMR

This book presents the work of the RILEM TC 279-WMR, whose purpose was to facilitate the use of waste, marginal and secondary materials for roads by investigating the performance of road materials containing waste through round robin tests and the development of standard procedures for their selection, preparation, and use. The structure of this book includes an introduction, five technical chapters, and a conclusion. The topics addressed are: the use of asphalt binder additives such as plastic and rubber; the combined use of aggregate and filler substitute in paving mixtures (construction demolition waste, rubber, and steel slags); the environmental assessment and the potential sources of pollutants originated from the use of this recycled materials.
