Concrete pavement and its reduced environmental impact
Concrete road pavements reduce environmental impact when compared with asphalt pavements. This Pavement Note summarises the latest findings which compare sustainability aspects of key heavy-duty pavement options. It provides agencies and decision makers with information to assist in meeting sustainability targets.
Concrete pavements typically comprise 20% or more recycled materials, demonstrate a lower environmental impact over long lives, exhibit low noise, reduce fuel consumption (and CO2), reduce lighting costs, reduce heat island impacts, absorb half of the CO2 generated in cement production, and increase corridor resilience during extreme weather events.
