EROSION CONTROL ON ALBERTA HIGHWAYS

Between 1983 and 1986, several projects were undertaken to control erosion on Alberta highway projects. The aim in each case was to control the erosion of backslopes, sideslopes and ditches as well as to control the amount of sediment entering watercourses. Products known as gridlock, enkamat, curlex and velmat as well as burlap and steel sheet piles were incorporated in the design of these installations. It is felt that tensar, enkamat, curlex and burlap are too light to withstand the erosive forces in the area of medium erosion potential. The velmat section has not yet been evaluated. Gridlock, on some installations was undermined and proved ineffective. Further evaluation is required, and this will commence in the spring of 1987. (Author/TRRL)
