Gravel Roadway Maintenance in Cold Regions

摘要

Many surface treatments are available for the treatment of gravel roadways incold regions. Primary concerns are the control of dust, stabilization of the surface to avoid rutting and potholes, and prevention of adverse effects of spring breakup. Calcium chloride has been the primary product added to Alaska's gravel roadway surfaces for this purpose. Several treatments are reviewed, including calcium chloride, lignosufonate, asphalt emulsion, Earth Material Catalyst Squared(TM), Road Oyl(TM), sodium montmorillonite, and no additive.
