Video: Tarmac UK promotes its permeable asphalt
Lafarge Tarmac has developed a permeable asphalt able to rapidly absorb a large amount of water.
The company highlights the problems of areas susceptible to heavy rains and floods where the asphalt can absorb 4000 litres of water in a minute.
“During these periods this characteristic can aid in delaying the discharge of surface water into water courses or drainage systems reducing the risk of overwhelming systems and causing flash flooding,” said Lafarge Tarmac.
“During periods of rising temperatures and intense rainfall, water stored within the system evaporates creating a cooling effect reducing surface temperatures.”
To test their creation, the company recently conducted an experiment and poured 4,000 liters of water in a parking lot covered with the permeable treatment. By the time the last drop of water made it to the ground, the rest of the water had already been absorbed.
