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

Local contractor P. Flanigan and Sonsí Winchester Recycling facility in Baltimore produces 100% recycled crushed graded aggregate base. The recycled material is being used on SHAís $12.4 million widening project along MD 295 (Baltimore Washington Parkway) between I-695 (Baltimore Beltway) and I-195 in Anne Arundel County.

ìP. 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,î said Pierce Flanigan IV, the companyís president. ìWe 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 grade aggregate base upholds the standards of SHA for materials to be used in infrastructure projects.î

So far, both plants that SHA approved for GAB recycling have saved more than 13,000 tons of virgin aggregate. SHA has certified two local crushed aggregate recycling centers to incorporate recycled base into SHA projects. SHAís Office of Materials and Technology evaluates each project that uses recycled aggregate for its effectiveness for a project and environmental protection.

ìI applaud the innovative use of recycled aggregate for construction projects throughout the state,î said Neil J. Pedersen, SHAís administrator. ìSHA 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.î
