Kolding Municipality and the asphalt arm of the contractor NCC took a 900-metre stretch of Ny Esbjergvej, a busy road between Vejlevej and the motorway roundabout, and split it into four equal sections. Three were laid with new surfaces at the end of August; the fourth got ordinary asphalt as a control. The binder in road surfacing is normally a pure oil product. Here it is resin, residues from used frying oil, and a by-product of paper production.
The machines worked between six in the evening and six in the morning to keep the traffic moving. NCC’s product manager expects the new surfaces to last as long as the traditional one, and that is exactly what the trial has to prove: the municipality and the contractor will spend the next few years watching how each section holds up under the cars. Road surfacing is a sizeable share of a municipality’s emissions, so the test is running on a live road rather than in a laboratory.
So…:
Where could you run your next experiment in public instead of in a lab?
