Less equipment means concrete has better environmental advantages; especially during the initial construction phase. Cement.org
suggests the average fuel demand for concrete requires about 9,000 gallons less than asphalt. The strength of concrete also allows for a thinner sub-base with less materials. After reaching its end-of-life, it can be crushed into aggregate, reused for new projects, and the rebar can be recycled. Smaller environmental benefits include less energy required to illuminate concrete roads and smoother rides for vehicles (the reduced pavement deflection allows for 100s of gallons saved for trucks).
