C&D Recycling

Maryland Highway Administration Partners with C&D Company
The Maryland Department of Transportation’s State Highway Administration (SHA) is working with the local construction industry to develop what it calls 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 (GAB), a material used on a roadway prior to paving operations. The recycled material is being used on SHA’s widening project.

Pierce Flanigan IV, president of P. Flanigan and Sons, says, “We are proud to receive approval from SHA and hope the use of recycled products becomes 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.”
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 evaluates each project that uses recycled GAB for its effectiveness for a project and environmental protection. SHA says it hopes 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,” says Neil Pedersen, SHA 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 also has worked with other contractors to use recycled GAB.

R. Baker & Son Completes NYC Demo Job
R. Baker & Son All Industrial Services, a demolition contractor based in Red Bank, N.J., has announced that it has completed a demolition project in Brooklyn, N.Y., for N.Y.-based utility company Con Edison. According to a company press release, Con Edison purchased the property and required the demolition of all buildings on the lot.
The lot was located in a residential and commercial area near downtown and contained many buildings constructed of masonry and brick walls with wooden floors and structural members, according to the company. To ensure safe demolition and to protect the surrounding public and active structures, the company says it developed a health and safety plan and a work plan before beginning the project. Included among the plans were fencing in the demolition area, emptying fuel storage tanks and sending the product off site for recycling and the removing of asbestos.

Before demolition activities could commence, the company says the structures needed to be abated of asbestos containing materials (ACM). ACM consisted of roofing materials, piping insulation, boiler insulation and gaskets. The insulation and gasket materials were abated using standard asbestos removal procedures. Because of the structural instability of the roofs, a variance was obtained to abate the ACM roofs using mechanical means and wet methodology.

The company adds that for the buildings to be safely demolished, several wall bracing systems needed to be installed.

Before beginning mechanical demolition, R. Baker & Sons conducted a significant amount of manual demolition. According to the company, careful surgical demolition needed to be conducted to separate the structural members along a shared common wall that needed to remain.

Metals, concrete and brick were sent off site for recycling. Wood timbers were salvaged and sent to a mill for reuse as architectural wooden beams and hardwood flooring.
