Compost Use on State Highway Applications

CURRENT COMPOST USAGE BY STATE DOTS

In order to determine the current usage of composted products by State DOTs, as well as their potential for increased usage, various information was gathered by surveying all 50 State DOTs. Once collected, this data was compiled into the following information sets: State DOT Compost Success Stories (case studies), Catalogue of State DOT Compost Usage Experience (50 State Summaries) and State DOT Compost Specifications tables.

To better illustrate the successful utilization of compost, and composted products, on State DOT and other highway related applications, a series of fact sheets which describe various compost utilization projects documented from across the United States were developed. We have provided case studies that illustrate a variety of potential applications for compost, as well as case studies from a variety of geographical regions, representing different climatic conditions and soil types. By providing these case studies, we hope to show highway managers that compost can be used successfully, across the country, in a variety of applications and conditions.
