Experimental research on the solutions to improve subgrade of pavement of dike using inorganic binder for stabilization

Abstract

     The dike structure requires specifications like that of pavement when the dike is integrated with the road. The pavement structure of dike consisting of base and subgrade layer is generally covered by high-density soil. In order to stabilize the pavement structure of dike, the subgrade layer is often taken into consideration. This paper introduces the subgrade stabilized by cement and fly ash to improve the bearing capability of dike structures. The initial results indicate that, depending on the type of soil, fly ash content should be used between 10-15% by weight of dry soil, in wich a part of fly ash acting as micro aggregate plays an important role in improving the bearing capacity of the base layer of road-dike.
