RECONSTRUCTION OF A CEMENT-STABILIZED FLY ASH

This paper describes the reconstruction of a 20 year old, badly disintegrated cement stabilized fly ash subbase. The approach chosen, for both economic and environmentally sound reasons, was the beneficial use of fly ash from coal fired power plants for the renewal of the old subbase materials. The methodology used has proved useful for development of full scale applications. The required amount of cement is mainly dictated by the required environmental quality of the product in terms of leaching rates. The technology may also be applied for other waste materials, such as dredging sludge and fine fractions from demolition wastes.
