... 78 Conclusions The primary objective of NCHRP Project 10-86 was to develop a Recommended Practice to assist transportation agencies and industry in implementing a performance-based process for design and selection of alternative culvert and storm water drainage pipe systems on highway projects. The procedure developed has been described as a Recommended Practice in standard AASHTO format.

... 79 • Integrated use of best available practices • Expandable framework enabling modifications as new methods and materials are developed • Flexible framework enabling customization to address individual agency needs The Recommended Practice provides a standardized framework to ensure technical robustness, completeness, and transparency, while maintaining the ability of agencies to use their local experience to assist in alternative pipe system selection. Risk associated with using new products and practices is mitigated through the use of such a framework.
