'Highways' is a comprehensive textbook on all aspects of road engineering. This new edition, written by a team of acknowledged experts in the field, teams up with 'Transport Planning and Traffic Engineering' to become a worthy successor to O'Flaherty's classic 'Highway Engineering' set. This fourth edition covers road location and plans, roadwork materials, surface and subsurface moisture control, pavement design and construction, thickness design of bituminous and concrete pavements and road maintenance and rehabilitation. The content has been expanded and thoroughly updated to take into account new developments in the subject, making it essential reading for students of civil engineering.

Key Features

comprehensive coverage including less well-covered subjects such as maintenance contributions from both academic and professional engineers


Undergraduate and postgraduate students of civil engineering. Junior qualified engineers and technicians
