Angélica Vázquez-Ortega, an assistant professor in the BGSU School of Earth, Environment and Society, is working with the agricultural community to answer a question that is at the root of her research: “Is dredge material good for soil?” Within those dredged materials are some important soil nutrients.ĭr.
This paper was sponsored by TRB committee AFP70 Mineral Aggregates.A Bowling Green State University researcher hopes to impact Lake Erie’s water quality by using dredged sediments from the lake and adding them to farm soils.Įach year, more than a million cubic yards of sediment are dredged from Lake Erie in an effort to keep shipping channels and commodities moving in and out of the Port of Toledo.The objective of this paper is to exemplify the beneficial use of dredge material in road construction. By improving scientific knowledge and understanding of the impact dredge material may have on the economy, it may be possible to gain sufficient confidence in the material to allow larger scale and more widespread use. After proper treatment, dredged material has the potential to become a major contribution toward sustainable development and can reduce the quantities of primary resources needed for activities such as construction. Fillers are widely used in road construction and various other industries, due to its small average particle size and chemically active silt/clay fraction. Dredged material is a valuable resource that can be used as filler, which is useful for the applications aside cement composites. Major ports are in need of an environmentally sound and economically feasible solution for this potentially hazardous material. The dredging of these waterways worldwide produce large volumes of dredged material, containing various contaminants, making its disposal increasingly problematic. Sustainable Use of Dredged Materials in Roadway Constructionĭredging is an essential process for the maintenance and development of ports, harbors and waterways for navigability.
