cement stabilization of subgrade soils

The strong uniform support provided by cement stabilization results in reduced stresses applied to the subgrade A thinner cementstabilized section can reduce subgrade stresses more than a thicker layer of untreated aggregate base Subgrade failures potholes and road roughness are thus reduced Moisture intrusion is the nemesis pavement bases
