DEVELOPING STRUCTURAL DESIGN MODELS FOR ONTARIO PAVEMENTS

This paper describes the applications of layered system analysis in designing Ontario pavements. The Brampton Test Road experiment provided this investigation with various data on material properties, climatic conditions, traffic, and performance. Test sections were analyzed by using Bistro and Chevron computer programs, which predict the structural response of stresses, strains, and deflections in pavement sections. The moduli values required for the analysis were derived from laboratory test data provided by The Asphalt Institute. The calculated structural responses were then correlated to observed field behavior and performance of test sections. Pavement responses, as predicted by the layered system analysis, could be closely related to observed behavior and performance. The analysis shows relationships existing between observed surface rut depth and vertical compressive strain on the subgrade surface. The measured Benkelman beam regounds and calculated subgrade surface deflections are also correlated. Charts to predict pavement performance for various peak Benkelman beam of Brampton base materials are 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 this system is incorporated into the overall pavement management system in Ontario.
