Asset Management Guide Addresses Needs of Local Agencies
The Minnesota Local Road Research Board has published a new guidebook to help local agencies get started on developing a consolidated asset management system. The guide addresses the particular needs of smaller groups to effectively and optimally manage their roadways, buildings, vehicles, equipment and other assets.
Roads & Bridges: Structural fiber choice for thin concrete pavements can have a significant impact on quality
A recently completed research project, funded by the LRRB and MnDOT, is featured in the January 2020 edition of Roads & Bridges.
LRRB Announces 2020 Research Projects
In December, the Minnesota Local Road Research Board met and funded 13 new research projects to address issues facing the Minnesota transportation community, including vehicle-pedestrian crashes and changes in how urban speed limits are set.
LRRB Research Implementation Committee Announces 2020 Projects
The Minnesota Local Road Research Board, through its Research Implementation Committee, has awarded funding to develop new educational and guidance materials in 2020 on nine transportation topics.
Asset Management Guide for Local Agencies
An introduction to all aspects of consolidated asset management for smaller departments, from getting started to an overview of software programs, the benefits of life-cycle cost analysis and the need for risk management.
Lightly Surfaced Roads (LSR) Training & Workshop Curriculum
A Light Surface Treatment, also known as a bituminous surface treatment, is a relatively new method for preserving a gravel or dirt road surface. The LRRB developed a half-day training curriculum to help counties and townships select the right treatment and successfully apply it.
Signing for Effective Roundabout Approach Speed Reduction
A recent LRRB project, “Strategies for Effective Roundabout Approach Speed Reduction,” provides the methodology to select, install, and evaluate treatments at different locations. This project had two goals: To analyze […]
Full Depth Reclamation (FDR) for Urban and Suburban Street Application
Two recent LRRB studies validate the assertion that FDR is a viable and cost-effective option for urban and suburban asphalt pavement rehabilitation: Full Depth Reclamation for Urban and Suburban Street […]
System Preservation Guide – A Planning Process for Local Government Management of Transportation Networks
Local transportation agencies are facing severe challenges in keeping roads safe and in good repair. Among those challenges are aging infrastructure, increasing material costs, and stagnant or decreasing funding levels. […]
Mitigating Frost Dips Over Newly Installed Centerline Culverts
In 2016, the LRRB published a Transportation Research Synthesis “Mitigating Frost Dips Over Newly Installed Centerline Culverts (PDF).” It gathered the following information via a survey of 24 northern states […]
Autonomous Vehicles – What Should Local Agencies Expect?
Project will develop guidance on preparing for and adapting to connected and automated vehicle (CAV) technology, including policy and infrastructure development. Researchers may develop a local agency repository for CAV resources […]
Effectiveness of Fog Seal on Chip Sealed Low-Volume Roads
This project will develop a resource guide about the effectiveness (application & cost) of fog sealing over chip-sealed roads. It will include a survey/interview of local agencies, followed by analysis […]
Pavement Performance of Overlays and New Construction Related to Ride Quality and Reflective Cracking
This project will develop a resource, possibly a quick reference guidebook, for practitioners to better understand pavement performance of overlays and new construction related to ride quality and reflective cracking. […]
Expanding the Transportation Workforce in Local Agencies: Awareness Building Activities and Development of the Training Course Roadmap for Future Civil Technicians
The goal of this project is to generate more candidates for hard-to-fill technician positions through an awareness-building campaign about transportation careers, and the development of a training course roadmap for […]
Pedestrian Crosswalk Policy Development Guidelines
This quick reference guide helps local agencies select appropriate crosswalk treatments based on roadway type, vehicle volumes and posted speed limits.
Guidance for Bicycle Facility Selection and Design
Minnesota is recognized as a leader in bike friendliness; however, local agencies struggle to know how to best accommodate additional users, specifically bicyclists, within their transportation system. This research implementation […]
