TxDOT has defined the critical performance factors for erosion and sediment control products and has established minimum performance standards which must be met for any product seeking to be approved for use within any of TxDOT’s construction or maintenance activities. The standards include:
- How well the product protected the seedbed of an embankment or a drainage channel from the loss of sediment during simulated rainfall or channel flow events; and
- How well the product promoted the establishment of warm-season, perennial vegetation.
By statistically analyzing the performance data produced through controlled performance tests at Texas A&M Transportation Institute (TTI) Sediment & Erosion Control Laboratory (SEC Lab), TxDOT is able to maintain minimum performance standards for each classification of products evaluated. For a product to be placed upon TxDOT’s IAPL, the product must meet (or exceed) all adopted minimum performance standards for that application. Failure to meet any of the adopted minimum performance standards will automatically reject the product from being placed on the IAPL.
The IAPL is designed to assist engineers/designers in selecting and reviewing erosion and sediment control products that have been evaluated according to ASTM D8297 standards and have met TxDOT performance thresholds.
