Kimberlite tailings suitability of this material for use in bituminous mixes. The laboratory studies indicate that kimberlite tailings can be used in subbase and base course layers in a road pavement. They can also be used in bituminous macadam as the base course and in premix carpet as a wearing course. A 1-km-long road was constructed near the diamond mine using kimberlite tailings, and its performance was monitored during a period of 1 full year. The road's performance was found to be satisfactory. However, since kimberlite is one of the fastest weathering rocks found on the surface of the Earth it is
Buffalo Head Hills kimberlite field kimberlite province, along with the Birch Mountains kimberlite field and the Mountain Lake cluster. It is located about north of the city of Edmonton in the Buffalo Head Hills of northern Alberta. The area lies within the Canadian boreal forest and is sparsely settled. Access is via Alberta Highway 88. Deep beneath the BHH kimberlite field lies a 2.0 to 2.4 billion year old Precambrian craton called the Buffalo Head Terrane, which has no exposure at surface. The Precambrian craton is overlain by about of Paleozoic and Mesozoic sedimentary rocks, which are covered by as much as of unconsolidated glacial
