Are there any standards/regulations for kerb profiles on F1 tracks?
Guys,
since I've been doing my tracks in drivable format, 3D kerbs became a neccessity. They are easy to do using Blender, but I realized I know neither what the most "popular" (or most used) kerb profiles are, nor if there are any regulations or standards regarding kerb profiles for F tracks. I've been experimenting with different kerb profiles and found to be the most fun the one that is about one meter wide, the track-side edge is elevated 5 cm and the outer edge is elevated 23 cm. This will cause the car bump a bit if you drive on the kerb, but it wont make the car go airborne What is the reality about kerb proifles? Any help and info is most appreciated. bio |

Thx!
Though, what I'm really looking for is like the "cross-section of the kerbs". Must have used the wrong expression. Sorry about that. bio |

I always wondered about this too.
Anyone know what kerbs are made of? I always guessed it was concrete or something. |

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. DG |
