Snowplow – Cool!
This video, designed for second and third grade children, tells the story of 10-year-old neighbors who had a near-accident with a snowplow. City and county public works departments are encouraged to visit schools in conjunction with this video to build connections with their communities and take an active role in safety.
Asphalt Pavement Maintenance – Field Handbook
This field manual provides guidelines for preventive asphalt pavement maintenance techniques for a variety of distresses and conditions.
Best Practices Handbook on Roadside Vegetation Management
This handbook was written to provide guidelines for effective management of roadside vegetation for local agencies, and highlights seven best management practices (BMPs) that were identified through research, surveys, and discussion with industry experts.
Best Practices Handbook on Asphalt Pavement Maintenance
The purpose of this handbook is to provide background information about the importance of pavement preservation and preventive maintenance, as well as present maintenance techniques for a variety of distresses and conditions.
Pothole Repair: Proven Practices
This 14 minute video provides an overview of the causes of potholes and repair methods. Three types of patching methods, permanent, semi-permanent and temporary, are presented along with the guidelines for selecting the most appropriate techniques.
Urban Mailbox Installation Guidance
Using a series of dramatic crash-test clips, this video illustrates the potential dangers of mailbox installations on high-speed roadways, and suggests safer, cost-effective alternatives to standard wood posts and other designs that penetrate windshields on impact.
Utility Cut Repair: Doing It Right
This video explains how using research-tested repair techniques and materials saves money, headaches, and time for both drivers and public agencies. It also serves as a educational refresher for maintenance staff.
Traffic Control: What Works?
This video discusses how engineers develop reasonable, research-based traffic control strategies and apply engineering judgment to select speed control devices.
What is the LRRB? (1995 version)
A short look at what the Minnesota Local Road Research Board does, and how it benefits city and county engineers, officials, and citizens.
Roadway Design: Balancing Safety, Environment and Cost
This video looks at the issues that must be considered when designing roads in Minnesota, and how approved designs meet these three key issues.
Asphalt Overlays: The Four P’s
In this video, meteorologist Mike Fairbourne explains the Four Ps involved in asphalt overlays: planning, preparation, production, and placement.
Seal Coating: A Matter of Science and Skill
Quality seal coating requires both science in design and skill in application. This video shows emulsion and aggregate spreaders in action and explains the project management necessary to maintain an efficient seal coating operation.
Asphalt Crack Treatment
The video discusses the differences between cracking filling and crack sealing and between routing versus sealing. Computer animation helps illustrate key concepts.
Pavement Repair: Do the Right Thing at the Right Time
Using nontechnical terms, pavement material samples and other aids, a moderator explains how engineers gather data on pavement and underlying soils, then discusses the factors considered in making rehabilitation decisions.
Weather and Loads: The Effect They Have on Roads
While focusing on how pavement materials are affected by weather and loading, this video covers the basic concepts of pavement engineering, including fatigue, bearing capacity, and thermal expansion. It is a technical topic, designed for a general audience, with tabletop cross-section models to illustrate principles. Damage caused by overweight vehicle loads is also discussed.
