Highway Erosion Remedial Measures

Document Type: Proceeding Paper

Part of: Sediment Transport Modeling

Abstract:

Soil erosion from highway ditches, cut slopes and fill slopes present a continuous problem to roadway designers, geotechnical engineers, and construction and maintenance personnel from environmental, aesthetics and roadway maintenance viewpoints. Very often the prevention of sediment transportation is required before vegetative cover establishes itself on a newly constructed grade. This is required to minimize stream pollution in environmentally sensitive areas, to prevent deep slope, and ditch gullying and to prevent blockage of culvert drainage structures. Over the last 5 to 8 years serious consideration has been given by Alberta Transportation and Utilities to the problems of soil erosion along the highway system which have defied treatment by conventional methods of erosion control. Such problems have been remedied using improved strawbale designs, concrete mats, geosynthetics, synthetic products, and gabions.
