Sand spreaders can betruck-mounted (fig. 14-42) or towed (fig. 14-43).Spreading hot sand over ice with conventional sandspreading equipment (fig. 14-43) is considered to be oneof the most effective ways of producing traction on icedFigure 14-43.—Towed sand spreader.Figure 14-42.—Truck-mounted sand spreader.surfaces. In this operation, the particles of hot sandembed themselves in the surface and thus resist removalby traffic and wind.For best results, the heated sandshould be applied to the iced surface as quickly aspossible.Loose sand, applied with the sand spreader, is alsoused to produce traction on iced surfaces. This methodis generally satisfactory, but because the sand is notfirmly bonded to the ice, it is blown off the surface bywind and traffic. This method is more effective whenapplied to surfaces that are wet and when freezingtemperatures are expected.14-35
