Research on High-grade Highway Roadbed Construction of Filling by Lime Modified Soil

Expansive soil is a kind of high plasticity clay that would seriously damage the high-grado highway subgrade engineering,especially would has deformation effects on subgrade engineering and large-scale structures.Doped lime was improved the nature of expansive soil so that the indicators have reached the use requirements of embankment filling,and can solve the problems of spoil and environmental.
