In which publication is rigid pavement design presented?

• A. AAHSTO 1993 PDG
• B. Concrete Pavement Design Manual
• C. Pavement Management Systems Guide
• D. Federal Highway Administration Manual

Answer: (A)

The American Association of State Highway and Transportation Officials (AASHTO) 1993 Guide for the Design of Pavement Structures (PDG) provides comprehensive guidelines specifically for the design of rigid pavements. This publication presents methods for determining pavement thickness and structural requirements based on traffic loads, soil characteristics, and environmental conditions. The guidelines also include load transfer mechanisms and considerations for joint design, which are critical for the durability and performance of rigid pavement systems.

While other publications may cover concrete pavements or related topics, they do not focus exclusively on the design principles and methodologies for rigid pavement as the AASHTO 1993 PDG does. Thus, it serves as a primary reference for engineers working on rigid pavement design.
