Application of Class C Fly Ash and Quarry Dust Mix for Utilization as Subbase Material in Flexible Pavement

Depleting good quality natural aggregates and soils call for the need of use industrial by-products waste materials in road construction. Use wastes construction consume large quantities resolve issue their safe disposal. Class C fly ash is by-product from thermal power plants while quarry dust left behind during quarrying processes. This study investigated application class mix utilization subbase layer flexible pavement. The mixed were studied with help unconfined compressive strength test, repeated load triaxial durability test microstructural analysis. mixture 90% plus 10% was found to be suitable respect criteria used as material Owing formation cementitious phases pozzolanic reaction, proposed demonstrated significantly higher resilient modulus than conventional granular material. service life ratio pavement 1.2 1.26 fatigue rutting respectively compared an economical well sustainable solution
