Asphalt working with the environment.

Asphalt and recycled asphalt in use work in harmony with the environment. Numerous leaching studies¹ demonstrate that asphalt easily meets all European limits for emissions to water. 

Asphalt is used to line drinking water reservoirs, fish rearing ponds, and it is also used to line landfill sites containing domestic and hazardous wastes due to its excellent waterproofing and durability.
