The new edition of this book is a crucial guide for those involved in the science of pavement design. It provides an in-depth analysis of the principles underlying material behavior, pavement design and maintenance, making it essential reading for pavement engineers and infrastructure experts who are faced with practical design issues for which transient standards are insufficient. The new edition explores different construction types and levels of cost efficiency around the world and concentrates on an understanding of the behavior of pavement materials and of the real meaning of tests carried out on those materials. Covering soils, granular materials, hydraulically-bound materials (including concrete), and asphalt, this book explains their various properties and the way in which they are affected by such matters as compaction, water content and binder content.
