UK company simplifies ‘rubber asphalt’ process
Ground rubber from scrap tyres has resilient properties that can be used to enhance the performance of construction products. For the asphalt industry, which currently depends on materials with very high embedded energy costs – polymer-modified bitumen is expensive in carbon terms both to make and to transport and store – asphalt made using bitumen modified with rubber concentrate from ground recycled tyres could therefore offer a welcome solution to greenhouse gas emissions associated with traditional asphalt manufacturing.
