March pavement workshop schedule, format change

The Extending Pavement Life through Pavement Preservation Techniques, Strategies, and Preventative Maintenance workshop previously scheduled for March 14 in Brainerd has been canceled. The March 22 in-person session has shifted to a virtual format, and the March 28 virtual session will be held as planned. We hope you'll join us online for the session that works best for you!

New surveying and mapping hybrid courses available

Three new MnLTAP courses will introduce you to land surveying and mapping within the civil engineering design and construction industries! These courses cover surveying and leveling, angles and mapping, and construction staking, and each will include online learning as well as an in-person workshop. These courses will take place in April and May, and all of them are eligible for Roads Scholar credit.

Roundabouts: speed reduction treatments,
pedestrian experiences

How can road designers get drivers to slow down at approaches to roundabouts—and keep themselves and pedestrians safe? Two new resources from the Minnesota Local Road Research Board (LRRB) offer strategies: a quick reference guide identifies treatments for a range of settings, and a research report offers ideas to improve pedestrian experiences.

Applying fog seal to chip-sealed roads can
improve performance

Applying a chip seal to asphalt on low-volume roads is a popular pavement preservation method, but it can cause various problems, including public complaints. New research from the LRRB indicates that in some situations, applying a fog seal after a chip seal can improve asphalt performance—and public satisfaction—cost-effectively.

Preparing for PFAS in your community

PFAS (per- and polyfluoroalkyl substances) chemicals pose health and environmental risks for many communities. A post on the American Public Works Association–Minnesota Chapter website offers ideas for preparing elected officials and residents to deal with this issue. A summary report of a 2022 PFAS forum for airport personnel is also available.
