Arizona Chemical Begins Construction on 100% Recycled Asphalt Bike Lane
Arizona Chemical has started construction on a 100 percent recycled asphalt pavement bike lane in Rotterdam, Netherlands. Rotterdam is the first city in the Netherlands to use 100 percent recycled asphalt in a sub, base and top layer of a bicycle road. This is the first time 100 percent recycled asphalt has been applied on all three layers of pavement in the country.
Because of road performance issues such as rutting, cracking and water damage, the percentage of recycled asphalt mixed with virgin asphalt has been limited to about 30 percent on average globally. Arizona Chemical developed a biobased rejuvenator for recycled asphalt that regenerates used bitumen in the mix. The additive is derived from crude tall oil, which originates from pine trees. Trials using the rejuvenator have been successful with 70 percent reclaimed asphalt in the mix, and similar results are expected with 100 percent.
With the higher percentage of recycled asphalt used, there will be less of it in landfills. Not having to transport fresh bitumen to the mixing plants will reduce the carbon footprint associated with asphalt production and result in considerable cost savings.
The project is a collaboration between the Port of Rotterdam, Rotterdam Municipality, KWS Infra and Arizona Chemical.
