Have you signed up for the RDI Webinar - Chemical Treatment Categories and Specifications?

The Road Dust Institute develops practical training courses on the use of chemical treatments in unpaved road amnagement and presents this training on a national basis. Training is offered through both on-site and web-based courses. In May we began a series of webinars. To download a pdf copy of upcoming webinars with brief descriptions click here.

CHEMICAL TREATMENT CATEGORIES AND SPECIFICATIONS - This webinar introduces the different chemical treatment categories, why they are grouped that way, and under what circumstances each category can be appropriately used. Provisional generic specification language for each category is also discussed. Risk based options for procuring chemical treatments and chemical treatment services are introduced.

Date/Time: Thursday, November 13, 2014, 2:00 - 3:30 pm CDT

This webinar is 90 minutes in length.  The presentation takes about an hour and 30 minutes is available for questions.  A certificate for 1.0 professional development hours (PDH) will be issued to individuals registered for the webinar. Cost: $50 for non-members, free for members (please contact staff for the discount code prior to registering). REGISTER for Webinar.

3rd Road Dust Best Management Practices Conference

Jointly held with the Transportation Engineering and Road Alliance (TERRA) group, the 3rd Road Dust Best Management Practices Conference was held February 3-5, 2014 in Minneapolis, Minnesota. Beginning with a pre-conference Unpaved Roads Workshop on Monday, February 3rd, it continued on February 4th as local, state and county road practitioners, as well as researchers and federal agencies came together to identify best practices and lessons learned. The conference also featured national and international experts presenting on environmental compatibility and sustainability, general and international best practices, and unique and extreme conditions as they related to dust control and low volume roads.

February 5th saw the start18th Annual TERRA Pavement Conference (and continuation of the Road Dust BEST MANAGEMENT Practices Conference). This one-day conference presented sessions that examined current practices and implementation of new pavement research and technology. National and local trends and innovations were examined to expand attendee understanding of pavement challenges and solutions.

Presentations from the Road Dust Best Management Pracitces (RDI) portion of the conference can be viewed here.



There are millions of miles of unsealed roads around the world which are managed by a wide assortment of national, state, and local authorities as well as private entities. Unacceptable levels of dust, poor riding quality, and impassability in wet weather are experienced on much of this global unsealed road network. Although it is acknowledged that these roads are fundamental to the economies of almost every country in the world, many of the management practices followed leave much to be desired, with programs for dust control, chemical stabilization, low-cost upgrading, etc., largely overlooked.

In recognition of this, the Road Dust Institute is being developed to…”provide tools to manage dust on transportation facilities through research, education and technology transfer thereby supporting improvements in health, safety, mobility, environmental sustainability and livability. RDI's unique knowledge, experience and capabilities provides for collaboration, partnering and consolidation of resources to address the needs of industry, government and other stakeholders to reduce the impacts of dust.”

We are a group of organizations dedicated to all things related to road dust management and research. Currently we are composed of the Western Transportation Institute at Montana State University, University of Alaska, Fairbanks–University Transportation Center, Federal Highway Administration-Central Federal Lands Highway Division, University of Nevada–Las Vegas and University of California–Davis Pave-ment Research Center. We are always looking for new members!



  • Gravel Roads Academy

    A recent iniative by Compass Minerals has resulted in the Gravel Roads Academy. They are offering training on how to better maintain your gravel roads for superior stabilization, greater cost savings and better air quality. Click here to view their curriculum.

  • Erionite Advisory

    Federal health officials are calling for protective measures at job sites where workers may be exposed to erionite, a cancer-causing mineral similar to asbestos that is found in rock and soil in at least a dozen western states. Read story on msnbc.com or view the CDC NIOSH Blog.
