Examine your zipper

The Asphalt Zipper is a new grinding machine that mounts on the front of a front-end loader. The Zipper grinds a path through asphalt pavement to allow access to utilities in just a few minutes, saving hours of work for road crews. The machine was one of over 70 inventions on display at the Pacific Northwest Transportation Technology Expo, which was held last month in Moses Lake.

Analyze this

This Road Surface Analyzer collects information on roadway surface texture and ride quality, even while traveling at speeds of up to 75 miles per hour. Specific measurements include macrotexture, faulting, grooving, rutting, slope and road profile. The device has applications in other transportation modes, such as monitoring the surface condition of runways and surveying the track-pentograph-catenary system along the Northeast rail corridor. It was developed by the Federal Highway Administration, and was on display last month at the Pacific Northwest Transportation Technology Expo in Moses Lake.
