Abstract
In France, the beneficial use of dredged sediment in road construction is one of the main applications. Previous studies concerning the potential use of dredged sediments as a material filler and in road construction was performed in the laboratory by several researchers. [1] 2] [3] [4]. The previous experiments used cement and lime as a binder. In this study we tried to replace fly ash as alternative binders. It has been known that the addition of fly ash improves the geotechnical properties, due to the pozzolanic reaction and its role as a micro-filler. Usually, material stabilized with fly ash needs a longer curing period than conventional binders such as cement and lime, due to their pozzolanic reaction, which bring a
slow development of strength at early ages, especially when a large amount of fly ash is used. To achieve effectiveness of fly ash on soil stabilization work, some
researchers added a small amount of lime [5]. Trying to make a more productive use of fly ash would have considerable environmental benefits, reducing air and
water pollution. Increased use as a partial cement or lime replacement would also represent savings in energy because fly ash has been called a high-energy- based material.
