Pavement performance compared with asphalt properties for five contracts in Ontario

This paper analyzes pavement performance of five Ontario Ministry of Transportation contracts paved in 2011 in relation to the properties of asphaltic materials used during construction. Pavement cracking data collected in 2016 was compared with characteristics of asphalt cement supplied for paving and recovered from pavement cores at year five. A major finding was that the Extended Bending Beam Rheometer test; part of enhanced testing currently carried out on asphalt cement in Ontario, was more reliable at predicting pavement performance than the standard Superpave™ Bending Beam Rheometer test for both asphalt supplied to the contract and recovered from in-service pavements.
