Impacts of Gradation on the Property of Lime-Fly Ash Bound Macadam

Abstract:

This paper studied the lime-fly ash bound macadam mixed with different proportions of lime fly-ash and aggregates which is often used in construction projects, analyzed the impacts of the aggregate content to the unconfined compressive strength, modulus of compressive resilience property with various lime content and is showed that dense skeleton lime-fly ash bound macadam reached the desirable strength property and had good effect on pavement performance Therefore, it is concluded that lime-fly ash bound macadam with desirable property, replacing fine aggregates is achievable, Test results show that coarse aggregate of lime fly-ash stabilized aggregate can form skeleton structure and has the advantage of high strength and other better material properties which can meet the requirements pavement.
