Six-Year Performance of Ontario's Freeway Fibre and Polymer Modifier Trial Project

In 2008, the Ministry of Transportation, Ontario (MTO) completed a demonstration project to evaluate the impact of fibre reinforcement and polymer modification on the performance of hot mix pavement in an urban freeway environment. MTO has been carrying out trials evaluating asphalt since the implementation of Superpave(tm) in 1997, and while previous trials have primarily focused on binder aging and low temperature cracking, this project is intended to assess any reduction in reflective cracking, and improvements in fatigue performance of a major highway. The existing concrete pavement was overlaid with two lifts of hot mix to form a composite pavement. The project sections comprised vatying combinations of different polymer modifiers and performance graded asphalt cements. Fibres were used in all sections of te trial other than the control. Monitoring in the form of field evaluation and automated pavement testing was conducted to assist in the perfoermance evaluation of the pavement sections. Performance data included roughness, rutting, friction, and cracking. Results are provided in this paper. Details on the project, its construction, and conformance with the end result specifications for the material properties of the asphalt and mix are also documented.
