About LRRB

A rich tradition

For more than 45 years, the Local Road Research Board (LRRB) has brought important developments to transportation engineers throughout the state. Those developments range from new ways to determine pavement strength to an economical method for recycling asphalt from old pavement to new pavement. Today, LRRB remains true to its important mission: supporting and sharing the latest in transportation research applications with the state’s city and county engineers. These activities include a focus on implementation. Established in 1959 through state legislation, LRRB has sponsored more than 200 individual research projects over the last 15 years on a variety of topics. Current LRRB-funded research falls primarily into the following categories: design, construction, maintenance/operations, environmental compatibility, administration, and implementation.

Grassroots involvement

The transportation practitioners who are responsible for county highways and city streets best understand the problems and challenges in providing safe, efficient roadways. The LRRB makes it easy for them to participate in setting the research agenda.

How the LRRB works

Transportation practitioners submit ideas to the LRRB who selects and approves proposals. The Minnesota Department of Transportation (Mn/DOT) provides administrative support and technical assistance. Researchers from Mn/DOT, universities, and consulting firms conduct the research, and the LRRB monitors the progress.

Advances

Recent research sponsored by the LRRB helps to improve the quality of Minnesota’s transportation systems. The impact of this research multiplies as more and more engineers see the potential applications through the LRRB Research Implementation Committee's technology transfer efforts.

Making a difference

The LRRB's current research agenda includes projects to explore land information sharing, offer rural safety workshops, update the crash tool application software, look into the benefits of porous pavements and to evaluate the data for performance of the storm water treatment technology.
