Better than you think
"Concrete road surfaces ?
No thanks, when was the last time you rode over an adverse cambered, rippled concrete surface in the wet ?"
Today and at 100 mph...except for the rippled part. Our roads are smooth. What's nice is no oil that floats to the surface, unlike tarmac.
They won't go to concrete. It wouldn't meet the EU noise regulation targets for roads, tyres, cars, trucks etc etc etc etc etc
That is a valid point. In residential areas where a freeway goes through, there are sections of road that are paved with a special low noise tarmac that also happens to allow water to drain through in a most excellent way. The tyres only kick up water about 1/2 as much and 1/2 as high making visibility and traction so much better. The typical volume level is 78 db.
No no no no, no. That's what they tried I'm the 70s during the oil crisis on the m27, the design life turned out to be nowhere near expected and maintaing the road has cost an arm and a leg, not to mention the noise at every joint.
Really? Our concrete roads have a lifespan of 40+ years. We have roads in place that have been around since the 1960's that still look good. When they do decide to do something to the surface, they just mill it about 50 mm, then add a new top layer. The composites they add to the concrete mixture is extremely durable and does not chip up, nor does it compression set under the weight of the vehicles like tarmac which leave grooved trackswhere the tyres run. Initial cost is high, but you make it up in not needing to do repairs and maintenence over the life.
Traction is my favorite thing about concrete. Now with the UK wanting to ban tyres made with Benzene, it is said tyres will have reduced traction. Lower traction tyres and less grippy asphalt are 2 things I don't like.
