For more than 50 years, the Local Road Research Board (LRRB) has brought important developments to transportation engineers throughout Minnesota. Those developments range from new ways to determine pavement strength to innovative methods for engaging the public. Today, the LRRB remains true to its important mission: supporting and sharing the latest transportation research applications with the state’s city and county engineers.

LTAP Training and Resource

If you missed Minnesota LTAP's April training sessions, the following resource and online tutorial are still available:

  • Local Concrete Flatwork Specifications
    Download a copy of the Minnesota Concrete Flatwork Specifications.

  • Workzone Safety Tutorial (Online)
    A new online tutorial is available for new, seasonal, or temporary staff to learn about the fundamentals of work-zone safety and the basic concepts of the work-zone area. This tutorial addresses many of the hazards inherent in road and street work and how these dangers can be minimized to keep motorists, pedestrians, and employees safe. The training includes a slide presentation, video, and a question/answer section to check comprehension of the material. All reading assignments are available online within the tutorial, so no additional books or materials need to be purchased. For more information, or to start the tutorial, click here.

Research Services FY2012 Annual Report Now Available

On behalf of the Local Road Research Board and the Minnesota Department of Transportation, we are pleased to present the Research Services FY2012 Annual Report, which highlights both LRRB and MnDOT research activities in FY12.

You might also be interested in our LRRB At-A-Glance and Research Services At-A-Glance publications, which include lists of active research projects as well as completed reports and implementation products.

To receive a hard copy of one of the above documents, contact Sandy McCully at Sandra.mccully@state.mn.us or 651.366.3768.

Some research highlights:

  • “Maintenance of Recreational Trails” (Report 2011RIC05) leveraged past LRRB-funded research into best practices for preserving trails to design and administer a workshop for city and county maintenance managers. (See Technical Summary on page 154 of the annual report, or click here.)

  • “Material Testing Rates for Low-Volume Roads” (Report 2012-17) will help local governments save money by reducing the amount of testing required for the materials going into local roads. (See the Technical Summary on page 144 of the annual report, click here.)
