You may not think of fescue grass as an asset, but when vegetation fails, it can lead to pavement or bridge failure as the ground supporting the overall structure erodes. NCHRP Research Report 1155: Tools and Technology for Roadside Vegetation Asset Management: A Guide, from TRB's National Cooperative Highway Research Program, describes ways to promote and implement roadside vegetation asset management (RVAM). The guide offers suggestions, including support for promoting and updating plans.

Supplemental to the report is NCHRP Web-Only Document 429: Investigation of Tools and Technology for Roadside Vegetation Asset Management details both available and emerging tools and technology.
