TRB conducted a webinar on Monday, September 12, 2016 from 2:00PM to 3:30PM ET on a new compaction device that can serve as a tool to improve soil-cement test specimen preparation. The plastic mold (PM) device can produce high-quality test specimens for soil-cement pavement layer thickness design testing, laboratory mixture design testing, and construction quality assurance testing. This webinar discussed the design and operation of the PM device and specimen properties. The presenters also discussed how the device can be utilized for Mechanistic-Empirical Pavement Design Guide (MEPDG) material inputs, laboratory applications, and construction quality assurance.
This webinar was requested by the TRB Standing Committee on Stabilization of Geomaterials and Recycled Materials. A certificate for 1.5 Professional Development Hours (PDHs) was provided to attendees who register and attend the webinar as an individual. Contact Reggie Gillum at
RGillum@nas.edu for instructions on receiving a copy of the recorded webinar.
Here are the slides.
