Cats eyes!

[TWR]

Has anyone noticed? they seem to set the cat's eye's higher in the tarmac, obviously causing more pounding on the Suspension, is this only in our area? do they do they same in your part of the UK?

What I've noticed most is how many of them on the motorway need replacing. Can hardly notice they are there on some stretches.

Maybe you should name stretch of motorway that houses the cats eye's that have been mounted higher than usual up here so anyone that drives past that way could then remember and maybe help gauge it for you. How could you tell anyway I'm pretty sure the cats eye housing's made of rubber, are they made out of something different in your area?

[TWR]

The Majority are made out of Cast, & yes there are some made out of Rubber but I dont think they are Vast as the rubber does perish, Wrongn3, I did not state a Motorway but the area around where I live, Lancs.

[R1Geezer]

the idea is that you don't run over them!

[Old_Geezer]

I doubt that. That is how the lens are cleaned.
Suprised about suspension concerns though. Surely not that bad.

What is just being nasty is the way they're replacing islands in the road with what apperas to be triple height kerbs. As far as I can tell it must be in the hope of destroying any wheel that hits them, and with any luck, cause a major accident when the car spins.

[R1Geezer]

yes they are designed so that the lens is cleaned when cars run over them but the idea is to stay to the left of the white line, so Percy must have realised that a lot of motorists would tray over them and utilised that.

I used to ride over them as a kid on a bmx and I couldn't feel them, maybe twr needs some new suspension as his sound like they're shot to bits.

There are three main sorts now. The traditional cast iron bed with rubber pad holding the glass reflectors, stick on reflective studs ( now mainly used for temporary works as it was found as sson as anything hit them, they became unstuck reflective studs!) and solar LED cats eye, which charge up from solar power and then stay on permanently through the night (bit unnerving when you first see them in your mirrors!). These are quite expensive (£54 ea I think), so when I'm working on road works replacing the tarmac, they have a crew with a corer that cuts them out first. They then have to be sent away to have the surrounding tarmac taken off them!
