Sustainability can be achieved with the focus on reducing waste, reusing material onsite, recycling waste and using recycled products. Recycled resources such as RAP*, allow old road surfaces and re-used aggregates to be used instead of virgin aggregates preserving natural resources and minimising the emissions from quarrying and transporting the materials. Diverting waste materials from landfill reduces the impact on biodiversity and reduces the energy consumption and emissions from transport where recycled materials are reused in close proximity to the site of reprocessing. Recycled aggregates also have lower embodied energy, require less energy consumption, less bitumen to produce fresh asphalt than virgin asphalt mixes resulting in an overall reduction in the Greenhouse gas emissions produced (CO2).
