Abstract:

A limited study to determine whether automatic discharge controls for salt and abrasive spreaders exhibit performance characteristics superior to those of conventional manual controls is described. Only a long-term investigation could accurately predict actual savings, but the study gave the order of magnitude of potential savings. Manual controls now used to maintain desired spreading rates were found to provide some potential savings over no controls, but savings provided by using automatic controls were much greater because of considerable improvement in the uniformity of spreading. In every case, the automatic system showed significant materials savings in comparison with the manual system. The automatic system did a much better job of eliminating areas of overspreading and underspreading--especially when the speed history of a truck varied considerably. The automatic system will maximize the safety and uniformity of driving conditions for the public and minimize environmental damage and unnecessary expense to the taxpayer. /Author/
