水砕スラグを利用した透水性舗装のアルカリ化抑制に関する実験的研究

Abstract

The present pavement is structure that does not infiltrate a rain water. Reason that prevents a bearing capacity decrease of a subbase/subgrade by the infiltration of water. A granulated slag occurs as a by-product, when a pig iron is manufactured. A granulated slag demonstrates a latent hydraulic property by an alkalinity stimulation. A sublease and subgrade that has the sufficient permeability, without causing a strength decrease by the infiltration of water by this can be produced. But, water that passed following the influence of an alkalinity stimulation medicine shows strong alkalinity. It is conceivable that this exerts a bad influence on environment. The purpose of this research is to restrain the alkalization of water passed a subbase and subgrade. Examining the combination of an alkalinity stimulation medicine that adds it to a granulated slag it is to maintain sufficient strength and permeability. It is examining about whether this material is able to apply to a roadway as a permeable pavement.
