Use of HDPE Drainage Pipes by DelDOT

Acceptance of new construction materials in infrastructure applications is typically slow, especially in the public sector. This can be attributed to an understandable conservatism when a substantial amount of money needs to be invested, when long-term performance is uncertain, and when safety is an issue. In recent years, however, acceptance of new materials has accelerated, mainly due to the increasingly high cost of construction combined with the availability of less expensive newly developed, custom-made, engineered materials. The ability to better predict the performance of these materials, which has resulted from sophisticated lab testing and the use of powerful computers, facilitates the acceptance process. A prime example of rapid acceptance in critical applications is the use of cost-effective polymeric materials (geosynthetics) in soil reinforcement, filtration, and separation. The acceptance of geosynthetics has evolved over less than 30 years, whereas during the past 10 years national design guidelines allow for permanent applications in critical structures such as retaining walls, bridge abutments, dams, and landfills.
