This disclosure relates to a method for treating roadways with sand, salt, or other like material generally applied during snow or icing conditions. Preselected overpasses, which extend across the roadway, are provided with storage means for containing predetermined quantities of sand or the like. A truck is driven along the roadway and stopped beneath one of the preselected overpasses. The driver then activates a dispensing means to cause a quantity of sand to be transferred to the truck. The truck then applies the sand to the roadway until it arrives at another overpass similar to the one described, whereupon it again stops and repeats the process. During intervals between storms, the storage means may be replenished at any time with a new supply of sand or the like.
