This research aims to study the feasibility of using crushed slag (CS) and fly ash (FA) to improve the physical properties of marginal LS prior to cement (C) stabilization for pavement applications. The pozzolanic materials in CS and FA were found to react with Ca ( OH ) 2 produced by hydration, which results in the formation of cementitious ...
