NYLON EROSION-CONTROL MAT (ABRIDGMENT)

The Pennsylvania Department of Transportation (PennDOT) has placed, and continues to place, emphasis on value engineering--the use of alternative cost-effective materials or procedures to perform a common function. As a result of this emphasis, a nylon erosion-control mat was recently field tested as a ditch lining on a project that was originally designed for rip-rap or paved-concrete lining. This nylon mat, installed with either a bituminous or wood cellulose surface treatment, provided a functional and economic erosion-control measure. In the trapezoidal ditches calculated, nonvegetated velocities were as high as 20 ft/s and vegetated velocities were as high as 8 ft/s. The mat installation resulted in a 60-70 percent cost saving over the rip-rap or paved-concrete lining atlernatives. PennDOT has included this nylon mat in its general specifications as a result of the positive findings on this project. A significant benefit of this stabilizing fabric was the structural integrity it provided to the vegetation root system. The use of the nylon mat instead of the rip-rap or paved-concrete alternatives also resulted in slower final velocities and lower flow concentrations. (Author)
