Flexible Pavement Analysis and Design-A Half-Century of Achievement

This paper provides one person’s perspective on flexible pavement analysis and design methodology since about 1960. Some developments during the past 50-plus years briefly summarized include: mechanistic analyses; materials characterization; mechanistic-empirical (M-E) pavement design methodologies; accelerated pavement testing; non-destructive pavement evaluation and overlay design; pavement management; and, improved construction practices. Some observations on education and training in pavement engineering are also included.
