Natural Pozzolans in the Pacific Northwest and their Beneficial Uses

Webinar: Natural Pozzolans in the Pacific Northwest and their Beneficial Uses

 

PRESENTATION ARCHIVE

OVERVIEW

The eruption of Mt. Mazama approximately 7,700 years ago created what is now known as Crater Lake. This eruption blanketed the Pacific Northwest with volcanic ash. This volcanic ash has been collected from several locations in Southern Oregon near the Oregon Institute of Technology campus. This volcanic ash has been tested and shown to have properties beneficial of a natural pozzolan. This seminar will present the results of a significant laboratory program to determine the natural pozzolanic capabilities of Mt. Mazama volcanic ash. In addition, information will be presented on a field application using the material to create ADA accessible trail surfaces.

KEY LEARNING OUTCOMES

  • Attendees will learn the location and natural pozzolanic properties of Mt. Mazama volcanic ash.
  • Attendees will learn trail surface requirements for ADA accessibility.
  • Attendees will be given information on how to use Mt. Mazama volcanic ash for trail stabilization.

TEACHING MODULE

Looking for a simple lesson plan outline? Here's a snapshot of the curriculum developed by this project, for faculty who might be interested in incorporating it into their transportation courses.

OVERVIEW

Vehicle operating dynamics data have a fundamental impact on the design of roadways, but collecting this type of data is not part of your typical college curriculum. Instead, engineering students are handed a textbook, leaving them without a firsthand experience of how accelerations and decelerations “feel” to the driver, the ultimate consumer of their designs. Seeking to change this norm, Roger Lindgren and C.J. Riley, civil engineering professors at the Oregon Institute of Technology, undertook a NITC education project to incorporate more real-world data collection and analysis into transportation courses...
