Recycled Concrete Study Identifies Current Uses, Best Practices

The Federal Highway Administration's (FHWA) Pavement Recycling Team recently completed a year-long review of recycled concrete aggregate (RCA) state-of-the-practice use by five State transportation departments. "The review's goal was to identify the current state of use and then transfer that knowledge to other State highway agencies," says Jason Harrington of FHWA.

Recycled Plastic Soil Nails Provide Boost to Missouri Slope Stabilization Project

Soils for highway embankments often deteriorate over time because of repeated wet-dry and freeze-thaw cycling. This eventually leads to recurring surface slope failures when the strength of the soil deteriorates to the point where it can no longer maintain stability. A popular technique for stabilizing new embankments or strengthening older slopes is soil nailing, which reinforces the earth slopes with arrays of slender pins driven or drilled into the soil.
