Effectiveness of stabilized expansive lime soil and construction quality control

The swelling of the expansive soil when wetted and shrinkage when dried may cause the deformation of subgrade and even endanger the security of building.Therefore,for road sections of expansive soil the stability of the roadbed is the key to the success of a project.On the basis of the consolidation mechanism of the lime stabilized soil and a practical example were discussed the construction mainpoints for stability of the road section of the expansive lime soil,as well as the construction quality control of the road section.
