Includes full color illustrations. The increased use of underground space for transportation systems and the increasing complexity and constraints of constructing and maintaining above ground transportation infrastructure have prompted the need to develop this technical manual. This FHWA manual is intended to be a single-source technical manual providing guidelines for planning, design, construction and rehabilitation of road tunnels, and encompasses various types of road tunnels including mined, bored, cut-and-cover, immersed, and jacked box tunnels. The scope of the manual is primarily limited to the civil elements of road tunnels.

The increased use of underground space for transportation systems and the increasing complexity and constraints of constructing and maintaining above ground transportation infrastructure have prompted the need to develop this technical manual. This FHWA manual is intended to be a single-source technical manual providing guidelines for planning, design, construction and rehabilitation of road tunnels, and encompasses various types of tunnels including mined and bored tunnels (Chapters 6-10), cut-and-cover tunnels (Chapter 5), immersed tunnels (Chapter 11), and jacked box tunnels (Chapter 12). The scope of the manual is primarily limited to the civil elements of design and construction of road tunnels. FHWA intended to develop a separate manual to address in details the design and construction issues of the system elements of road tunnels including fire life safety, ventilation, lighting, drainage, finishes, etc. This manual therefore only provides limited guidance on the system elements when appropriate.

This comprehensive handbook covers all aspects of design, production, and construction of precast concrete tunnel segmental lining, with the best practices in the field included in one book for the first time. New and current design methods and quantitative analyses are considered in line with ACI and ASTM codes, as well as a full selection of global standards for the reliable design of the product and all components. Also incorporated are new applications of science and technology, such as new admixtures, and the latest manufacturing processes and precisions, such as tight dimensional controls and high repeatability cycles. With detailed guidance from world-leading practitioners, this is the definitive international technical and practical manual on these linings, forming a one-stop reference for tunnel engineers and an invaluable resource for advanced students in civil, mechanical, and mining engineering.
