Abstract: Based on the field tests and theoretical analysis , the applicahility of f1y ash as fillers in the subgrade widening construction was analyzed. The mechanical responses of two parts which were separately filled by the fly ash and soil with geogrid were compared. The settlement rules of the suhgrade and foundation in the suhgrade widening construction filled by f1y ash and reinforced by geogrid were studied. The rationality and applicability of f1y ash in filling the high embankment were also analyzed

Key words: road engineering, Subgrade widening, high embankment, fly ash subgrade, mechanical response, settlement rule
