US 40 And MD 213 Maryland

Asphalt Outperforms Concrete at Maryland Intersection

Reprinted from the Ohio Asphalt Magazine Fall 2013

The intersection of U.S. 40 and MD 213 topped the list of “trouble spots” for the Maryland  State Highway Administration (SHA) network as early as 1993.  The high daily traffic count and the large percentage of truck traffic resulted in excessive pavement deformation which needed to be addressed once or twice a year at a great expense.  The Asphalt Industry was challenged to come up with a solution for the eastbound travel, passing and right-turn lanes of U.S. 40 at MD 213.

Just west of Washington, D.C., I-66 in Fairfax County, Va., is one of the busiest commuter routes in the country.

Between 162,000 and 178,000 vehicles per day travel on I-66—far greater traffic levels than were expected when the road opened to traffic in 1963. A major pavement-rehabilitation project in 2011 and 2012 turned the stretch of road from a nightmare to a dream, with a smoother, quieter ride.
