水砕スラグを利用した透水性舗装の路床, 路盤に関する実験的研究

Abstract

The purpose of this reserch is the application to the roadway of permeable paving that have water infiltration and water retention. These realization enable to foster ground water, to activate of a plant, to reduce of cummer season road surface temperature, to reduce the burden of a drainage facility of sewerage etc. It assumed that nature puts closer it to the water circulation that has basically. Reason that permeable paving was not adopted to a roadway until the present, when an infiltration rain water entered in a subbase, a subgrade and be because it was thought that pavement destroys it by a traffic load. Water granulated slag occurs as a by-product, when a pig iron is manufactured. Demonstrate the latent hydraulic property that is the characteristic by an alkal stimulation medicine, and an improvement subbase, a subgrade are prepared. It has without causing a strength decrease even if depend on the infiltration of water and that have the sufficiennt permeability. And examination is being added from dynamic, physical orasite experiment about whether this material is able to apply to a roadway as permeable paving.
