Guidelines for Lime Stabilization

If the ajority of the soils on a m project are IIIC and/or poor quality IIB4 soils in both cuts and fills, lime stabilization may be considered for use. If the soils are very micaceous, however, do not use lime, as it does not react well with micaceous soils. Use cement stabilization for micaceous soils.
