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
Kimberlite tailings at higher temperature to obtain Zeolite-A. The product is useful as builder in detergent formulation. With a view to assessing the potential use of kimberlite tailings in road works, the Central Road Research Institute engaged in a detailed laboratory study. Kimberlite tailings were characterized to determine their physical engineering properties. Results indicate that kimberlite tailings are a marginal material and possess adequate strength for use in the construction of rural roads. The feasibility of utilizing this material for the construction of various layers of road pavement by adopting stabilization techniques was investigated. A study was also undertaken to assess the
