FIA Kerbing Specifications

[Brian.Novak]

Anyone know where I might be able to find the proper specs for FIA Kerbing? By way of the google, I've managed to find a few different types with rough dimensions but no real specs/construction guidelines for them. Anyone have any ideas where, or maybe someone who worked on the Austin project I might be able to ask? Specifically looking for standard apex and exit kerbs with proper paint types and schemes etc.

You might try google search under 'FIA curbing'

There are numerous sites.

FIA doesn't like to spell it that way!

I've went through most of them already. Actual construction specs are hard to come by. Found a couple companies that make them though.

[Peter Olivola]

You might try spelling it "kerbing."

I believe I found them in a very remote area of the FIA website a few years ago while researching information to build a local track. They're in an appendix.

[Daryl DeArman]

Appendix O has some generic descriptions of the various styles of FIA kerbs. Page 6.
Explaining how they are to be drawn. Maybe a further search by thier style name will help.

Also found this:

Permanent circuit kerbs are concrete, current temporary circuits also use GRC (Glass Reinforced Concrete) and, in the case of Singapore, rubber.

The profile depends on whether it is an entry, exit or apex kerb and the speed profile for the corner.

FIA kerbs are all 800mm wide.

Apex kerbs rise from 0mm at the track edge to 50mm at 400mm from the track and then stay flat to the rear edge (800mm from the track). These are known as bevelled kerbs.

Exit Kerbs are a bit more complicated to explain but have a 50 to 100mm 'ripple' depending on speed profile. Each ripple is an 800 x 800mm square with a dual grade on the surface on the diagonal to create the ripple against the previous and following 800mm square. The ripple obviously has its tapered rise in the direction of travel. Just to confuse you further this can be a positive kerb (also known as a Vallelunga kerb) i.e. rising from the track surface or a negative kerb (also known as a Melbourne kerb) falling away from the track. Again this is dependant on speed profile. Negative kerbs have only a 25 to 50mm ripple.

Optionally a 2m wide strip of artificial turf to discourage use of the verge behind the kerb is installed at kerbs.
