EVOLUTION OF FLEXIBLE PAVEMENT DESIGN SYSTEMS

The author reviews earlier thinking and concepts as they impacted on experience based on empirical methods which were and continue rather widely to be the basis of pavement design and evaluation. He conveys his belief that a proliferation of possible theoretical approaches has prevented concentration on any one, and recommends future focus on elastic layered methods as the besst hope for soon developing widely acceptable theoretical models to supplant the still widely used empirical methods. Focus on layered model methods should not distract from still better finite element and stress-dependent modulus behavior models. The new approach recommended is based more on geotechnical, limited shearing concepts to improve understanding and treatment of individual material characteristics.
