LIGHTWEIGHT FILL MATERIALS FOR ROAD CONSTRUCTION

A lightweight fill is any material used to replace a heavier in situ soil to reduce the load on subgrade soils. The use of lightweight fills is increasing in many areas of the United States. Various materials have been used; however, because of their experimental nature there are no formal design guidelines specific to each material. Additional research is required to determine more specific design guidelines for each available lightweight fill material. The selection of a lightweight fill is generally based on local knowledge of each fill material. For any construction project requiring a lightweight fill, there may be several alternative materials to consider. However, due to a limited knowledge or unfamiliarity with these materials, design engineers might not consider them as an alternative. This synthesis has been written to help determine what technology and materials are available for use in road construction in areas where a lightweight fill material may be appropriate. The fills investigated are sawdust and wood chips, expanded polystyrene, foamed concrete, and shredded tires.
