– i – PERPETUAL PAVEMENTS: THE ONTARIO EXPERIMENT Submitted to:

A Perpetual Pavement is a flexible pavement designed from the bottom up to resist structural failure, minimize cracking and rutting, and last for 50 years or more with only periodic renewal of the wearing surface. In 2006, the Ministry of Transportation Ontario (MTO) will begin reconstruction of 11.3 km of Highway 402, near Sarnia, Ontario. The project will be constructed in three sections: a 4 km trial section of Perpetual Pavement with rich bottom mix as the lower binder layer; a 4 km trial section of Perpetual Pavement with Superpave 25 mm as the lower binder layer; and a control section of conventionally designed flexible pavement constructed with Superpave mixes. The Perpetual Pavement trials and control section will be instrumented by the Centre for Pavement and Transportation Technology (University of Waterloo, Ontario), to better understand how the different pavement structures react and perform under various traffic loadings and environmental conditions. This long term monitoring and instrumentation is a three way partnership with the Ministry of Transportation Ontario, Ontario Hot Mix Producers and Centre for Pavement and Transportation Technology
