Asphalt refers to a semi solid or viscous liquid which is primarily used for road construction. It comprises hydrogen and carbon compounds along with minor proportion of sulfur, oxygen and nitrogen. It is mixed with aggregate particles, such as stone, gravel and sand, for making asphalt concrete. Due to its high viscosity, asphalt needs to be heated before mixing with the aggregates. New technologies that could help in producing a consistently high-quality pavement are thermal imaging and intelligent compaction. Thermal imaging helps in measuring the temperature of the mat behind the paver. These new technologies may provide information which can be utilized for improving the consistency of compaction and paving operations. This book elucidates the prospective developments with respect to asphalt materials and paving technologies. It covers in detail some innovative concepts revolving around this domain. This book will serve as a reference to a broad spectrum of readers.

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.
