Slag-Soil Composites Application for Service Performance Enhancement of the Roads with Low Traffic Density

摘要

The existing problems of distant road-building materials transportation at limited financial resources determine the direction of alternative scanning. During rural highway construction it is necessary to use ferrous metallurgy waste and soils. The most reasonable is the application of slag together with soil in the form of slag-soil composites. Such composites proportioning and technology development of their application is an actual problem. The under test steelmaking slag are prone to independent silicate, calcareous and ferrous decompositions. That is why the development of technology of road subgrade construction with application of slag-soil composite is the result of our investigation. During a year subgrade should be effected by natural-climatic factors. In a year the revealed defects are eliminated and surfacing layer is placed.
