have been seeing alot of this 'high grip' road surface appearing on roundabouts, near ped crossings and on sharp bends, and out of curiosity have been testing its grippiness. im amazed, the car just wont skid or slide! just wondering if anyone has any other info on this?
after investigating it further, i though of the price of one speed camera, then compared it to an guestimate of what this surface would cost. i believe that this surfacing could help stop many accidents and crashes purely by reducing older (and newer) cars from sliding and skidding when the brakes are not as capable to stop from 30, when some kid runs in the road at a ped junction. is it just me or does this help the argument over the government looking at money making before saftey?

my friend thought this was a good idea to test the grippiness. this was all going very well until he got to the point where you do lose grip and things turned very nasty very quickly. just remember the stuff will give you better grip but you will be going a load faster than uaual if you do lose it!

There is also the fact that as the stuff is much sharper and rougher than standard tarmac, doing this will not make your tyres last very long!
Isn't it funnny that on other roundabouts/hazards they lay those stupid raised strips across the road to warn numpties that they approaching it, so that just when you need a nice safe grippy surface to brake they've put lovely skiddy white painted lines across that make the car skip and jump. Some people in road planning have had their brains removed, I swear it.

Its called shell grip. It is very expensive to lay. The stones are specially layered specifically to grip the tyre as it approaches the problem. Many pedestrian crossings are also being addressed with this surface in the controlled area.
Are we talking about this sandy coloured stuff that's now getting applied so generously, not to say extravagently?
If we are, it seems to me that a good deal of it is not very durable despite the high cost. I see plenty of areas where the stuff soon breaks up and becomes detached from the road surface, leaving rough and bumpy patches to add to all the other poor quality road surfaces we're now left with.
I haven't tried doing any hard braking on it, but I see plenty of skid marks on such areas, so some people seem to be managing some slippage on it.
Best wishes all,
Dave.

this really annoys me too. braking nicely and smoothly only to hit these lines and then slide/stop/slide/stop so bloody infuriating.
there need to be people in the highways department that actually understand road users and as such can lay a decent surface
I seem to remember that the full name of the stuff in question is 'Shell sure grip'.
When it first came to market and prominent use, it was absolutely amazing and still leaps and bounds ahead of other surfaces from a safety perspective.
Donnington Park track is surfaced with something similar and the grip around the track is awesome. Still came off the bike though!
The other stuff mentioned is that sandy stuff that appears to be 'stuck' on top of existing road covering and is way inferior to the Shell grippy stuff. I too often wonder why the sure grip is not more widely used. Does point towards money making rather than accident prevention. There would be a case for sticking this at most junctins and ped crossing, as well as roundabouts and the like. Would be a gross and net cost unlike Scameras!
