Right-of-Way Revegetation Challenge

Due to highly erosive slope grades and ditches, it was proving extremely difficult to establish vegetation on two segments of the Central Texas Turnpike Project. The project faced drought conditions, poor soils and sporadic but damaging rainstorms. This article describes how a flexible growth medium and turf reinforcement mat system was used to provide critical slope revegetation. The growth medium was chosen because it does not require cure time, provides immediate protection against erosion upon application, and absorbs and holds 15 times its weight in water, delivering more moisture to the seedbed for faster vegetation establishment. The reinforcement mat system was used in combination with the growth medium in ditch areas to protect against elevated levels of hydraulic lift and shear forces on slopes and in channels while encouraging fast turf establishment and long-term root reinforcement.
