Research Pays Off Webinar Series: Tire Derived Aggregate

  • Tuesday, July 17 from 10 a.m. - 11 a.m.

This webinar will examine the use of recycled tires as an aggregate in pavement design and implementation. Monte Niemi, president of NRRA member First State Tire Recycling, will be presenting.

TDA has 10 main engineering properties that make it superior to conventional soils. Some of the beneficial properties of TDA include: light weight, free draining, has 8x the thermal insulation of soil, and 50 percent voids, which eliminates potential moisture “wicking.” These properties prevent frost heaving, and have helped road engineers and contractors produce roads that have a longer life span and require less maintenance.

Sign Maintenance and Management for Local Agencies

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.
