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

These pictures illustrate one advantage of tandem plowing: The workhorse V-Plow, Big John, bulls back the rapidly accumulating snow berm, while a blade plow follows to remove the residue from the roadway to make it safer for normal traffic.Snow Removal; February 1964 Monthly Report, II-R-SR-7882, Physical Facilities - Roads - Snow Removal Operations

If the amount of snowfall is moderate, the plows can push the berms back sufficiently. Occasionally, after a heavy snowfall, it has been found to be economical to remove the snow with front-end loaders. This equipment is also used to remove extremely large snow berms from along the side of US-441 so that the next storm will not cripple removal operations.Snow Removal; February 1964 Monthly Report, II-R-SR-7896, Physical Facilities - Roads - Snow Removal Operations
