Categorization of Erosion Control Matting for Slope Applications

Erosion control is an important aspect of any Georgia Department of Transportation (GDOT) construction project, with the extreme negative impacts of high sediment loads in natural waterways having been well documented. Selection of a proper erosion control mat for protection of slopes on GDOT rights-of-way should be made with primary emphasis on the steepness of slope, which will govern the hydraulic stress to which the soil and vegetation are subject. Additional considerations to selection of erosion control matting include time to establish vegetation, followed by selection of a product made out of synthetic or natural fibers. GDOT has 79 approved products, produced by 19 manufacturers listed in QPL-62 dated May 29, 2015. Due to the high number of products which a designer can specify, a spreadsheet-based selection tool was developed to specify which QPL listed erosion control products are appropriate for given conditions. A laboratory-based investigation of the erodibility of coarse-grained soils was performed. The evidence shows that mean particle size is the primary variable in determining the raindrop splash displacement of sands. The effect of particle shape and void ratio on raindrop splash was minimal.
