Design of modified full depth asphalt for heavy duty pavements

This paper briefly discusses the design methodology proposed for industrial and heavy duty pavements. The loads on such pavements (up to 50 tonnes per wheel) preclude extrapolation from other design methods and it is argued that the use of mechanistic analysis is warranted. This paper briefly describes and comments on the steps involved in the design process. It is concluded that deep strength asphalt pavements, modified to include a high bitumen (high fatigue) asphalt subbase, must be considered with all the other pavement types in such applications.
