dc.description.abstractThis report encompasses a proposal to consider application of wastewater sludge to highway right-of-way. Conventional disposal of this sludge is a complex and expensive process and in some areas is severely restricted by land use and regulations. The report includes a literature review, a national survey of highway organizations and a hypothetical design analysis. Application of sludge to highway ROW can be beneficial by supplying nutrients required for plant growth, subsequent erosion stabilization and ultimate disposal of a waste resource. Disadvantages include negative public reaction, potential for contamination of ground and surface water, aesthetics, and relatively high costs. Preliminary findings of the report indicate the process is marginally feasible and recommends that a small pilot project should be conducted prior to full-scale considerationen_US
