MnDOT Evaluating Ideas for Research Implementation Funding

MnDOT is currently evaluating more than 25 research implementation ideas for its FY2018 research cycle. Project champions are competing for $650,000 in funds for demonstration projects that their unit, district or office implements to solve problems, save money, or change business practices. Each year, MnDOT solicits proposals from MnDOT staff who want to put local or national research into practice in their day-to-day work. Research Services staff are helping develop proposals that will be presented to the Transportation Research Innovation Group (TRIG) on April 4.

Partner States Get First Look at Minnesota Road Experiment

Nearly 60 one-tenth mile sections of Co. Rd. 8 and nearby Hwy 169 were recently treated with various combinations of fog seals, chip seals, crack seals, scrub seals and microsurfacing and a number of thin overlays. Data will be collected from these experimental test roads for three years and compared with the results of a similar experiment in Alabama, where the same test sections were also built on a low- and high-volume roadway, to see which techniques are the most effective for preserving road life.

Knowing While Mowing: GPS Keeps Maintenance Workers Out of the Weeds

Thanks to a research project that installed GPS devices in tractor cabs, MnDOT Metro District mowing operators have a better sense of exactly which areas they need to mow and which areas should be left alone. Five Metro District tractors were tested in 2015. This year, more than 40 tractors were fitted with the automated vehicle location (AVL) technology, which includes a GPS antenna, an on-board central processing unit (CPU) and an in-cab screen with a user interface.
