The AASHTO Guide to Pavement Design, Construction, and Management, Second Edition (2026), consolidates pavement engineering guidance into a single reference for agency practice. Chapter 1 provides a general overview of the guide and explains how the remaining chapters are organized. The fundamentals of pavement design are then discussed, building from basic principles toward the structural design of pavement types and their materials. Coverage extends through pavement construction and into pavement management practice, addressing both new pavements and the upkeep of existing networks. The guide brings together design, construction, and management topics that agencies otherwise consult in separate publications. It is intended for pavement engineers and agency staff responsible for design, construction, and management decisions on highway pavements.
