The particle diameter of the fly ash is 10-100 micron. The mixed stabilizer of waste stone and fly ash comprises 60-80 wt% of the waste stone, and 20-40 wt% of the fly ash. The composite stabilizer comprises 60-80 wt% of the covering material and 20-40 wt% of the fly ash.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Waste stone + Fly ash mixing and stabilizing layer; (BB) Waste stone layer
