In popular terms, rolling resistance is the resistance to movement caused by interaction between the tire and the road surface.
The less rolling resistance, the less energy needed for movement.
Thus, low rolling resistance pavements can reduce fuel consumption and save energy.
About one third of the energy consumption from the road transport comes from overcoming the rolling resistance between the tire and road.
In Denmark, the CO2 emission from the road transport alone is estimated to 4,6 mill ton pr. year. Implementing low rolling resistance pavement on the entire 4000 km of state roads in Denmark will provide a reduction in CO2 emission by 160.000 tons pr. year and saving the road users 64 million litres of fuel.
