Maryland Highway Administration Partners with C&D Company

The Maryland Department of Transportation’s State Highway Administration is working with the local construction industry to develop environmentally safe methods of recycling pavement for use on future highway projects. 

P. Flanigan and Sons’ Winchester Recycling facility in Baltimore produces 100 percent recycled crushed graded aggregate base, the material used on a roadway prior to paving operations. The recycled material is being used on SHA’s widening project.

“P. Flanigan and Sons has been using recycled materials for many decades. The Winchester facility is just one example of our continued efforts to make infrastructure and transportation construction more environmentally friendly,” said Pierce Flanigan IV, president of P. Flanigan and Sons. “We are proud to receive approval from SHA and hope the use of recycled products become more widespread. Through extensive testing, the Winchester plant ensures that the quality of recycled GAB upholds the standards of SHA for materials to be used in infrastructure projects.”

Using recycled crushed aggregate saves fuel that would otherwise be spent while mining for new material and its subsequent transport from quarries. Reducing fuel consumption has the added benefit of lowering vehicle emissions, which are harmful to the environment. Additionally, recycling pavement material conserves shrinking landfill space. So far, both plants that SHA approved for GAB recycling have saved more than 13,000 tons of natural aggregate.

SHA has certified two local crushed aggregate recycling centers to incorporate recycled GAB into SHA projects. SHA’s Office of Materials and Technology rigorously evaluates each project that uses recycled GAB for its effectiveness for a project and environmental protection. SHA envisions a future where recycled GAB will be part of the competitive bidding process on all resurfacing contracts.

“I applaud the innovative use of recycled aggregate for construction projects throughout the State,” said Neil Pedersen, SHA’s Administrator. “SHA is building environmentally-focused projects and the use of recycled aggregate is a step toward paving the way for a greener and more sustainable highway system.”

SHA has also worked with other contractors to use recycled GAB. David A. Bramble, Inc., an eastern shore contractor, has been certified to use recycled GAB for the ongoing $22 million US 113 widening project from Hayes Landing Road to north of Goody Hill Road in Worcester County.
