WTI

2008 Road Dust Management Practices and Future Needs Conference

Sponsored by the Bureau of Indian Affairs, EnviroTech Services, Inc., FHWA, Fish and Wildlife Service, National Park Service, North American Salt, US Forest Service, and the Western Transportation Institute

The main themes of this event included:

• Overview of road dust and adjacent area management;
• Current road dust management practices;
• Identifying knowledge gaps and research needs; and
• Developing recommendations for future needs that will assist practitioners, industry personnel and researchers by highlighting critical ideas and areas of focus.

Agenda

All events were held in the Coronado Ballroom at the El Tropicano Riverwalk in San Antonio. Links to individual presentations are provided below.
