CW - Asphalt Stone

In 2011, Canadian Wollastonite’s (CW) ortho-gneiss ore was certified by the Ministry of Transportation for Ontario (MTO) for use in major highway surface construction. This ore is approved as an FC1 and FC2 DFC/Superpave and SMA friction aggregate and is listed on MTO’s “Designated Sources for Materials”. CW’s ortho-gneiss is advantaged over many of the other sources in Ontario in that it is the province’s southernmost approved source of FC1 and FC2 aggregate.
