This book discusses the applications of fracture mechanics in the design and maintenance of asphalt concrete overlays. It provides useful information to help readers understand the effects of different material and loading type parameters on the fracture properties of asphalt concretes. It also reviews relevant numerical and experimental studies, and describes in detail design parameters such as aggregate type, air void, loading mode, and additives, based on the authors experience and that of other researchers.

Provides a comprehensive overview of fracture mechanisms in asphalt overlays Explains how to conduct fracture tests under different loading modes, including mode I, II and III Describes numerical methods for simulating road overlays made of asphalt materials
