Asphalt: Technology and Materials

Asphalt is a dark, sticky, highly viscous liquid or a semi-solid that is made of petroleum. It can be derived from natural deposits or as a residue of the distillation process of petroleum. It is used as a sustainable paving solution composed of filler, aggregates, and binder. It has various types such as mastic asphalt, natural asphalt, cutback asphalt, residual asphalt, asphalt emulsion, and asphalt cement. It becomes soft when heated and is elastic under some circumstances. It is primarily utilized in road constructions as a binder or glue mixed with aggregate particles to make asphalt concrete. Asphalt is also used for bituminous waterproofing products such as manufacturing of roofing felt and for sealing flat roofs. This book aims to shed light on some of the unexplored aspects of the technology and materials associated with asphalt. It consists of contributions made by international experts. This book will serve as a reference to a broad spectrum of readers.
