I was driving back from London on the M4 this morning, and delighted in driving a section of road somewhere around Swindon (iirc) that had been re-surfaced with a beautiful, black ‘render’. It was so smooth, the car became instantly silent as it fairly glided over the mile (or so) of fresh motorway.
Wouldn’t the whole of the UK benefit from such surfacing? If so, why is it only now being deployed in road building? Whatever the case, can we expect it to become the norm for road surfaces?
Ultimately, I would think that our quality of life would increase if road noise was universally reduced as it was for me this morning (however fleeting the experience!).
