Erosion Prevention During Highway Construction by the Use of Sprayed on Chemicals
Nine commercial spray on plastic chemicals were evaluated as erosion inhibitors. All the chemicals were compared with straw tacked with asphalt emulsion and with untreated soil. The cost of each chemical was also obtained to determine if the most effective chemicals were economically feasible. In Virginia there are three principal physiographic provinces. The soils in each province are significantly different in composition and erodibility. Two highway slopes with a vertical height of 15 to 20 feet and a slope of approximately 2:1 were selected to be tested in each province. It was found that the same chemicals were not the most effective in the different areas. Also, no chemical performed better or cost less than the straw tacked with asphalt emulsion in any of the three areas. However, some chemicals did show significant erosion protection and are recommended in cases where the conventional straw and asphalt are undesirable or unavailable. (Author)
