Abstract: The method of backfilling expansive soil, lime soil and geonets in staggered layers used in the disposal of weak expansive soil embankment is introduced. By the in-situ tests, the bearing capacity and rebound modulus of soil basement in different layering combinations are obtained and the differences among different combinations are analyzed and discussed. The results show that the structure of weak expansive soil plus lime soil; and the compound structural type of weak expansive soil, lime soil and geonets wrapped in the soil embankment are scientific and reasonable in the disposal of expansive soil embankment. With this structural type, not only the expansive soil along the road but also their strength can be fully utilized only when the requirements of design are satisfied by the construction quality of each structural layer.

Key words: expansive soil, lime soil, geonets
