The Road Dust Institute (RDI) has changed its name to the Unpaved Roads Institute (URi) to better reflect the increased interest general unpaved road management issues. We would like to welcome you to our new website.  First conceptualized in 2008, we are continually evolving with input and support from our founding partners and the Federal Lands Highway of FHWA.  Today, URi is ready to assist industry, local governments, and private landowners with the design and maintenance of our nation's unpaved roads.


URi Webinar Announcement

The Unpaved Roads Institute develops practical training courses on the use of chemical treatments in unpaved road management 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. View our upcoming webinars with brief descriptions here.

Providing Resources to Manage Unpaved Roads

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 Unpaved Roads Institute has been developed to…”provides tools and services to manage unpaved wearing surfaces on transportation facilities through research, services, education, and technology transfer, thereby supporting improvements in unpaved road and airfield management, health, safety, mobility, environmental sustainability, and livability. URi’s member’s unique knowledge, experience and capabilities present opportunities to collaborate, partner and consolidate resources to address the needs of industry, government and other stakeholders to optimize the performance of unpaved roads and airfields.”

We are a group of organizations dedicated to all things related to unpaved roads 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 Pavement Research Center. We are always looking for new members!
