REMEDIATION OF CONTAMINATED MATERIAL

摘要

The present invention relates to a method for the remediation of contaminated material, comprising mixing said contaminated material with fortification material and a filler, cold mixing the resulting mixture with an aqueous cationic bituminous emulsion having a pH of 2 to 5 and comprising 40 to 70 % by weight of bitumen having a penetration of from 15 to 200 pen; followed by breaking of said emulsion to give a remediated material in which the particles of said contaminated material are coated by a layer of bitumen. The resulting material is suitable for use in the construction of roads.
