Producing Vegetation on Highway Slopes Concurrently with and Subsequent to Highway Construction
Experiments on slopes in West Virginia highway corridors were established to ascertain methods of producing vegetative covers quickly during all seasons of the year. Persistent vegetation was established on stair-step graded cut slopes in one seeding operation compared to bench cut slopes which usually required two or more seedings. Uncompacted fill slope surfaces prevented erosion of approximately 400 tons of soil material/A during a torrential rain. Soil chemical binders applied without woodfiber or straw were unsatisfactory for establishing a vegetative cover. Woodfiber at 750 lbs/A was equal or superior to asphalt or other chemicals for tacking straw. German millet or weeping lovegrass in summer seed mixtures provided a vegetative cover quickly and controlled erosion while Kentucky 31 fescue and crownvetch became established.
