The Federal Highway Administration (FHWA) has proposed a regulation that it says will give state departments of transportation more flexibility in setting design standards for resurfacing, restoration and rehabilitation (RRR) projects on existing Interstate highways and other key arteries.
The proposal, published in the Federal Register on Nov. 24, would incorporate updated design standards—principally those issued in recent years by the American Association of State Highway and Transportation Officials (AASHTO)—and drop older versions of the benchmarks.
