Impact of Centralized Solid Waste Disposal on Highways
An EPA mandate requires that all solid waste be deposited in approved landfills by October 9, 1993. Regionalization of landfills will demand scheduled, year around hauling of heavy loads to the appointed landfills. Such an increase in heavy truck traffic can be expected to negatively impact South Dakotas state and local roads and bridges.
1 Develop a representative model of the solid waste disposal operation for SD.
2 Quantify the frequency and magnitude of axle and gross overloads by vehicle classification.
3 Estimate the impact (damage) of loads on city, county, and state roads.
4 Generate cost estimates of road damage and transport on a volume basis.
5 Recommend strategies to minimize impact and cost.
1 Reveiw literature pertinent to solid waste transportation and related pavement damage.
2 Gather operational data from Mitchell/Huron and Rapid City solid waste regions and pertinent public and private sources.
3 Generate a solid waste flow model for the solid waste regions incorporating one municipal, intermediate, and rural source for each regional facility.
4 Examine the effects of the equipment, truck configurations, and regional waste distribution on the model.
5 Use the model to predict routes, trip lengths, weights, and other factors for the solid waste regions.
6 Identify and quantify representative road sections within the study areas and project the damage due to solid waste transport.
7 Determine direct and indirect costs for each element of the flow model.
8 Propose strategies to minimize the impact efficiently and economically.
9 Provide a final report and executive summary detailing a literature summary, research methodology conclusions and recommendations.
