RALEIGH – The following are highlights from this week at the N.C. Department of Transportation. The stories below are also featured in NCDOT Now, the department's weekly newscast.
NCDOT Tests Masks Material in Asphalt
NCDOT, East Carolina University and S.T. Wooten construction company are teaming up to find out if recycled face masks can be used in asphalt mix to pave and improve roads.
The idea is in the very early stages of testing – which involves shredding recycled masks, then adding the material to the hot mix asphalt. With paving conducted at up to 300 degrees, the plastic fibers in masks become a fluid and act as a binding agent. Officials believe this could reduce indentations of the road.
A decision whether to fund the proposal for additional testing is expected later this year.
CASSI to Wrap Up at Wright Brothers National Memorial
Visitors at the Wright Brothers National Memorial have one more week to ride a first-of-its-kind electric, self-driving public transit shuttle. The Connected Autonomous Shuttle Supporting Innovation, or CASSI, will wrap up its three-month trial program Friday, July 16. So far, about 700 trips have taken more than 3,000 riders on the CASSI.
This marks the first trial of a self-driving vehicle at a recreational public lands site in the country. Once complete, NCDOT and the National Park Service hope the testing of the shuttle at a national park helps them learn more about how autonomous vehicles can safely and effectively be used.
