This paper describes the applications of layered system analysis in designing Ontario pavements. It was found that pavement responses, as predicted by the layered system analysis, could be closely related to observed behaviour and performance. The analysis showed relationships existing between observed surface rut depth and vertical compressive strain on subgrade surface. The measured Benkelman Beam rebounds and calculated subgrade surface deflections were also correlated. Charts to predict pavement performane (i.e. serviceability - age history) for various peak Benkelman Beam rebounds were developed and equivalencies of various tyeps of Brampton base materials were derived based on a criterion of equal loss of serviceability. The paper presents a structural design system for flexible pavements and discusses, through an example problem, how the design system is incorporated into the overall pavement management system in Ontario.
