Quick Summary

Stabilized pavement refers to a method used in civil engineering to improve the quality of local natural materials that are not ideal for use as a base course in road construction. This process involves mixing relatively small amounts of additives like lime, portland cement, pozzolana, or bitumen into the substandard material.1

The additives increase the strength and stiffness of the material by reacting with its surface. This also makes the material less permeable, reducing its susceptibility to water damage. Special machines are used to distribute these stabilizers into the top layers of the soil, typically between 8 to 20 inches deep. This stabilization process enhances the pavement's durability and performance under traffic loads.12

The strength and stiffness of the mix are increased by the surface reactivity of the additive, which also reduces the material’s permeability and hence its susceptibility to water.
