Sanding operations in progress after snow removal, Newfound Gap, Tennessee Great Smoky Mountains National Park When the storm abates and the plows finish clearing the roadway, the surface must be made safe for all traffic. Sanding appears simple, but a high degree of judgment is necessary to determine the proper mix to apply to the road. When the surface is soft, gravel (1/2-inch maximum size) is most effective. On ice, gravel is useless, but sand provides traction. When the road cover is melting, gravel must be used because sand washes away. Calcium and sodium chloride are mixed in varying degrees with the aggregate. In cold weather, the percentage of calcium chloride is increased, and in warmer weather, calcium choloride is not needed. Obviously, sanding isn't as simple as it looks... Sand truck.Snow Removal; February 1964 Monthly Report, II-R-SR-7898, Physical Facilities - Roads - Snow Removal Operations
