Advanced Horizontal and Vertical Alignment and Intersection Applications
- March 5 - 7, 2019 from 9 a.m. 4:30 p.m. (Tuesday) and 8 a.m. - 4:30 p.m. (Wednesday - Thursday) at the MnDOT Shoreview Training and Conference Center
This three-day workshop covers horizontal and vertical alignment with more advanced examples and challenges. Attendees learn how the three components of a road plan—plan, profile, and cross section—are integrated to account for intersections, drainage, sight distance, and quantities. Nearly every highway and street design effort involves some elements of intersections. The proper engineering of an intersection can be one of the most challenging tasks in road design. Topics involved in intersection design include general geometric parameters, alignment and grade considerations, intersection sight distance, design vehicle consideration, and pedestrian considerations and design.

Fundamentals of Roadway Design and Horizontal Alignment Workshop
- October 23 - 25, 2018 from 9 a.m. 4:30 p.m. (Tuesday) and 8 a.m. - 4:30 p.m. (Wednesday - Thursday) at the MnDOT Shoreview Training and Conference Center
This three-day workshop begins with an overview of road design fundamentals, including an introduction to plan reading and coordinate geometry, followed by an introduction to horizontal alignment and station control, design speeds and controls, and roadway standards. It also reviews how to use the Road Design Manual and accompanying technical memoranda and how to determine stationing and station equations, sight distance, curvature, and geometrics.

PPRA Webinar - Tools for Smarter Road Network Management
- Tuesday, October 30 from 10 a.m. - 11 a.m.
This webinar was developed and designed by experts across the industry. It includes technical information on treatments, best practice tips & tricks, and important how-tos of asphalt maintenance. Participants will learn foundational tools & concepts to easily make better decisions for road networks, budgets, and taxpayers.
Make smarter choices on a project-by-project basis
- Understand which asphalt treatment to use on a given project
- Learn to compare treatments “apples to apples”
- Calculate savings between various options & approaches
- Access easy-to-understand technical information
Maximize budgets with a macro view of your network & roadways
- Calculate & optimize the lifecycle cost of your roads
- Prioritize projects based on better “bang for buck”
- Understand & improve network health, instead of addressing one road at a time
Pavement Preservation & Recycling Alliance (PPRA) was recently formed to bring industry and agency together for pavement preservation. The organizations of Asphalt Emulsion Manufacturers Association, the Asphalt Recycling & Reclaiming Association, and the International Slurry Surfacing Association form the PPRA. Jointly, PPRA assists agencies by providing a centralized repository for comprehensive information related to pavement preservation and asphalt recycling and reclaiming. PPRA seeks to help agencies at the state, county, and local level to make the right choices for their road networks and be the best possible stewards of their roads and of taxpayer dollars.

Thinlay Pavement Preservation: A Contractor's Perspective
- Wednesday, November 28, 2018 from 1 p.m. - 2:30 p.m.
In an environment of limited public funding, it is important to employ cost-effective pavement preservation techniques that improve the pavement’s surface, protect its structure, and extend its service life. Thinlays are a widely used pavement preservation treatment that delivers the excellent performance required by pavement managers and agencies. This webinar will focus on proper application of Thinlays to achieve the highest performing pavement preservation solution for pavement owners.

TRB Webinar: Reducing Pavement Damage Due to Spring Thaw
- Tuesday, October 30, 2018 from 1 p.m. - 2:30 p.m.
The webinar will discuss techniques for reducing pavement damage due to spring thaw, especially on low volume roads. These techniques include improving geometric design, properly posting spring load restrictions, and modifying drainage systems. Presenters will highlight case studies of mitigation techniques from Minnesota, New York, and Alaska. They will describe spring thaw and provide practical mitigation examples that can be implemented into new and existing pavements.
- Billy Connor, Alaska University Transportation Center
- Steve Henrichs, Minnesota Department of Transportation
- David Orr, Cornell Local Roads Program
Moderated by: Ben Worel, Minnesota Department of Transportation
A certificate for 1.5 Professional Development Hours (PDHs) will be provided to Professional Engineers (PEs) who register and attend the webinar as an individual. For groups, only the person that registers and attends the session will receive a PDH certificate. Certificates of Completion will be issued only to individuals who register for and attend the entire webinar session
Some registrants will need to pay $55 to attend this webinar. Sign into MyTRB.org to view registration information.
Typical Sections, Cross Sections, Roadside Design, Quantities, and Earthwork
- December 18 - 20, 2018 from 9 a.m. 4:30 p.m. (Tuesday) and 8 a.m. - 4:30 p.m. (Wednesday - Thursday) at the MnDOT Shoreview Training and Conference Center
This three-day workshop focuses on roadside design and safety. Each day has interactive activities and case-study-based examples/working problems.
Typical and cross sections topics include typical section standards, elements, and development; grades and slopes; developing a typical section using the Road Design Manual and the soils letter; and contours and creating a cross section.
Roadside design topics include explaining how to determine and compute clear zone requirements and how to deal with obstructions, barrier design and placement, horizontal clearance to obstruction, ditch sections, and impacts of design speed on clear zone.
Quantities and earthwork topics include identifying pay items on a plan set, determining the appropriate units, estimating the amount of each item to be paid for as part of the project, preparing tabulations and final quantities, earthwork and mass balances, shrinkage and expansion factors for a variety of soil types, estimating earthwork quantities, and preparing earthwork tables and summaries.

This online distance-learning course was created to provide a concise, cohesive set of sign maintenance and management materials to employees of cities, counties, and municipalities. The development of this course stemmed from the realization that no consistent sign training is available locally and that many key maintenance staff are retiring without transferring their knowledge to younger staff. In addition, it is often challenging for maintenance staff to attend workshops and training in person, since their schedules change frequently and are often weather-dependent.
This course will help maintenance staff better understand sign materials, placement, installation, and retroreflectivity, as well as general maintenance and management practices. In addition, students will learn how to use and navigate the Minnesota Manual on Uniform Traffic Control Devices (MN MUTCD) and understand new federal requirements related to sign maintenance and management.
The course consists of 10 lessons, each containing a narrated presentation, video clips, and a quiz. Participants can complete the course, which will take about 10 hours, at their own pace.
- General overview
- Minnesota Manual on Uniform Traffic Control Devices
- Sign policy
- Sign materials
- Sign placement
- Sign installation
- Sign retroreflectivity
- Sign maintenance and management
- Addressing and street name signs
Cost: $65 ($75 to register for a Continuing Education Credit)

This three-day workshop builds on the Fundamentals of Roadway Design and Horizontal Alignment Workshop by providing information on basic twolane superelevation and shoulder applications. The workshop reviews several multi-lane and ramp applications and intersection considerations, drainage impacts from superelevation design, and spiral transition curves.
Additionally, this workshop covers the geometry of vertical curves, standards and design considerations, vertical curve sight distance criteria and some related design challenges, interactions of vertical curvature,
superelevation, and drainage.
