Soil stabilization is where the road is brought up to grade, millings are applied and then heavy equipment is rolled on the surface to compact the material. The average cost of soil stabilization is between $60,000 and $80,000 per mile, depending upon how much has to be done to bring the road up to grade. The normal paving of a road with new asphalt, versus soil stabilization, costs about $350,000 per mile.
