Article Preview

Fly ash has become increasingly wide range of applications in expressway as a new environment friendlymaterial, its range of applications are fromthe CFG( Cement Fly-ash Gravel) pile of soft ground、pavement admixture to embankment materials et al. Fly ash used in expressway has many advantages, such as, it can save farmland, has a small settlement after construction and low cost as a light embankment filling. In this paper, based on an expressway in Jiangsu province, the fly ash used as a subgrade filling, a series of fly ash laboratory and field test have been conducted. The construction technology, important construction parameters, construction process control and compaction quality assessment on fly ash have been analyzed on the basis of the tests result, the road performance and construction control key methods of fly ash obtained, which can guide scientific construction.
