Principles of pavement engineering offers sound engineering understanding to those learning, practising or researching in this field. It is concerned with the basic principles underlying material behaviour, pavement design and maintenance, and will allow the reader to move beyond a mere following of design standards and become able to tackle problems outside the scope of such requirements.
