| Abstract: | Fly Ash has been widely used in expressway＇s roadbed, as well as base and subbase of high-grade pavement. Especially, the subbase structures usually adopt lime and fly ash stabilized fine-grain soil（lime-ash soil for short） to replace previous common lime stabilized soil, that improves the engineering quality and service quality of road further. |
