Technical basis of Austroads Guide to Pavement Technology: part 2: pavement structural design

The Austroads publication Guide to Pavement Technology, Part 2: Pavement Structural Design is intended to assist those required to plan and design new pavements. It was originally produced in 1987 as a result of review of the NAASRA Interim Guide to Pavement Thickness Design (1979). In 1992, the Austroads Pavement Design Guide was revised to include an updated procedure for the design of rigid pavements and also relevant portions of Chapter 6 (Pavement Materials) and Chapter 7 (Design Traffic). An essential element in the use of the Guide is a thorough understanding of the origins of the design procedures, their scope and limitations. Accordingly, this report contains the following five technical reports detailing the technical basis of: 1. Chapter 1: 1992 Guide procedures for the design of flexible pavements; 2. Chapter 2: 1992 Guide procedures for design of rigid pavements; 3. Chapter 3: Guide to Pavement Technology Part 2 Design of flexible pavements; 4. Chapter 4: Guide to Pavement Technology Part 2 Design of rigid pavements; 5. Chapter 5: Guide to Pavement Technology Part 2: Development of design charts for lightly trafficked roads
