Evaluation of Lime-Stabilized Ariake Clay with Foaming Waste Glass as Pavement Materials

Abstract

Foaming waste glass, a new material produced from waste glass, is first briefly introduced. Secondly, the preliminary findings of the engineering properties required for improved pavement materials, namely unconfmed compressive strength qu, compressive splitting strength qs and the CBR value of the lime–stabilized Ariake clay (LA) with foaming waste glass (LAG) mixture, are presented on the basis of a series of laboratory tests. The potential effectiveness of foaming waste glass as a partial replacement for lime on the strengths of the LAG mixture is indicated by a comparison with lime-stabilized Ariake clay. A process for evaluating stabilized materials as pavement materials is described based on the results of a uniaxial test and pavement structure analysis. It is concluded that foaming waste glass can be effectively applied as a partial replacement for lime for the improvement of soft clay and that the LAG mixture could be used as pavement materials, considering not only its strength but its deformation properties as well.
