Title: Use of Recycled Materials in Highway Construction Author: David L Swearingen, Newton C Jackson, Keith W Anderson Subject: Aluminum, Asphalt concrete .
1) Concrete: It is a popular choice for the road construction purposes as they are solid material and can be used for building walls and local roads This method are considerably less prone to wear and tear defects like rutting, cracking, stripping, loss of texture, and pothol
Cost of construction materials continues to increase every year In addition, use of marginal materials results in early development of pavement distress, requiring more frequent repairs and rehabilitation and associated lane closures and traffic congestion in high-volume traffic areas
recycling materials generated during building construction, demolition, or renovation Typical construction and demolition (C&D) materials include wood, drywall, cardboard, brick, concrete, metal, insulation and glass
