The City of Edina Engineering Department has developed a temporary roadside turf irrigation system with inexpensive common parts for the roadsides of smaller city road and utilities reconstruction projects as a more efficient and cost-effective alternative to water truck irrigation.
The Local Road Research Board hosted “A Guide to Successfully Convert Severely Distressed Paved Roads to Engineered Unpaved Roads” on Oct. 29, 2019 from 10 – 11:30 a.m.
The LRRB was featured on Edina TV on Sept. 16, 2019. The City of Edina’s Engineering staff is testing a new irrigation system in hopes of finding a more efficient and cost-effective way of replacing grass and vegetation following a road reconstruction project.
A new guidebook, video and handout provide best practices for successful establishment of boulevard turfgrass after road construction.
This brief video highlights the topics covered in the LRRB’s guidebook, including Steps for Successful Base Stabilization, How to Choose the Right Additive, and Research on Why Base Stabilization Works.
Which specialty warning signs are necessary and effective, and which do more harm than good? The answer may surprise you.
Recent research shows that the city of Shoreview was on the right path in 2009 when it took the then-unusual step of installing pervious concrete pavement on the streets of the Woodbridge neighborhood to help control stormwater and pollutant runoff into nearby Lake Owasso.
Carver County staff received a grant through the Local OPERA Program to help purchase a brine-making system and support further research into the viability of using pickle brine in winter maintenance operations.
Students can learn more about the field of civil engineering and how to become an engineer in a new video and website produced by the Local Road Research Board.
In this video, we debunk three common roundabout myths and prove they are a viable alternative for intersection traffic control.
In this video, we address common roundabout myths and demonstrate why they are a viable alternative for intersection traffic control.
This video, shot near Thief River Falls, Minnesota, shows a comparison between traditional rumble strip designs and the newer sinusoidal rumble strips (a.k.a. “mumble strips”). Researchers are investigating whether sinusoidal rumble strip designs, which are much quieter, are effective enough to combat drowsy or inattentive driving.
This video accompanies a spreadsheet tool, which aims to assist local agencies in determining which hours of the day to consider using flashing yellow arrow (FYA) phasing.
This video gives an overview of the different types of chemicals available to public works entities to combat the toughest Minnesota winter conditions.
In this video, researcher Howard Preston explains what MnDOT is doing to learn the life expectancy of traffic signs.
In this video, pedestrians, cyclists, and motorists in Minnesota identify some common misconceptions about bike lanes.
Ever wonder why your road isn’t being repaired? This Minnesota Local Road Research Board video explains why roads go bad and why sometimes the worst roads aren’t fixed first.
Watch this video to see MnDOT-funded researchers transform parking lots into driving tracks to study the effects of weather and vehicle traffic on different deicing treatments.
