A four-mile section of the George Washington Memorial Parkway in Maryland will be repaved beginning in March, using an asphalt-recycling process that has not been used before in the East, according to the National Park Service.

The repaving is expected to close two of the parkway's four lanes for at least four months, although one lane in each direction will be maintained at all times. The construction is due to be completed July 15.

The section to be repaved extends from Glen Echo to Carderock. It is the first repaving of the 23 year-old parkway, and is required because of extensive roadway damage in the Glen Echo section from auto traffic and weather, according to Park Service spokesman George Berklacy.

The $594,000 repaving job is unusual, said Berklacy, because the asphalt road surface will be torn up and trucked to the Brigham and Day Paving Co. in Rockville where it will be crushed, heated and mixed with additional asphalt and then relaid on the parkway.

The Federal Highway Administration is paying $50,000 of the contract cost to demonsatrate the feasibility and economy of asphalt recycling in the area, said Berklacy. Recycling of such road surfaces is now being done in a number of places in the South and West.
