Description	In July, 1990, the ministry of Transportation of Ontario built trial sections on Highway 400, near Innisfil, to compare standard and modified HL 1 mixes in terms of their effectiveness to resist rutting and low temperature cracking. In addition to Premium Asphalt from Petro-Canada, the additives used for the trial sections include Novophalt, Neoprene, Vestoplast, and tire rubber, which had not been evaluated previously by the MTO. The selected test site represents a typical highway section in a colder environment experiencing heavy traffic induced rutting. The mix design for the trial sections was modified to yield results in 2-5 years.
