TxDOT/Texas Transportation Institute’s Sediment and Erosion Control Laboratory (SEC Lab) provides the transportation industry with a research and performance evaluation program for roadside environmental management. The program includes storm water quality improvement, erosion and sediment control, and vegetation establishment and management. TTI’s Environment and Planning Program operates this 19-acre, full scale, indoor/outdoor facility. Demand for the facility has steadily grown for over 20 years, necessitating the recent expansion to meet the industry’s research needs. With $350,000 annual funding from TxDOT, TTI produces and maintains the TxDOT Approved Products List for all sediment and erosion control products used by TxDOT on Texas roadsides.
