Researches on the Coal Fly Ash Applied to Saline Soil Improvement in Rural Roads

Abstract

There is a wide range of saline soil distributied in China , 4.88% of the country's land can be used for salinization land.The salinization of soil in Tianjin area is 6614200 acres among them.The saline soil characteristics of collapsibillity, expansion, corrosion resistance are easy to make the roads salt cause expansion deformation, melting trap net crack and potholes, falling off and any other diseases, thus it is currently an urgent need to solve the problem of saline soil improved road in the salinization area of rural highway construction.Research group in the Green Meadow Depression saline soil application, applies the power plant fly ash resources based on the technology support analysis, obtains feasible technology application results.
