Discussion Paper: Comments on "Ontario's Strategy to Enhance Asphalt Cement Quality"

Premature pavement cracking is a type of distress that has been gaining increasing attention in recent years. Much of MTO’s research into the distress has been focused on the quality of the asphalt cement. While this author agrees that the specifications for asphalt cement in Ontario need to be improved, the issues are much broader than just the asphalt cement. Nonetheless, MTO’s paper presents much of the background for their development of two new test procedures: the Extended Bending Beam Rheometer (ExBBR) test and the Double Edge Notched Tension (DENT). These tests were developed to address premature pavement cracking in Ontario. However, an examination of the data presented in the paper in support of the new specifications indicates that the conclusion may not be as certain as portrayed.
