Default Onroad Track Barriers

wazzup! Question for some of you... track barriers. More specifically, how do the top shelf tracks maintain/build/implement their track barriers? for example, here is the track for the BRCA touring car series...



How do they make/mount these barriers? Are they made of concrete and are permanent? If so, do they never change those parts of the layout? Are the off sections astroturf, or painted green? Does anybody have any technical information on how these are formed and implemented?

How do some of you guys mount the barriers at YOUR track? pics?

On that track the green sections are painted green. Not sure what raised square bits are made from but I would suggest either kerb stones, concrete lintels or red brick.

The corners (red and white painted) are made from cement which has been layed over the original curbs which we believe were concrete (we've had the track re-surfaced so we had to raise the curbs etc up.

The older concrete had some sort of screeding on it which helped the paint to stay on a bit better than the newer stuff.

The raised 'square' sections along the straighter parts of the track are blocks of wood screwed down and painted green. We considered more cement etc but the effort and expense to do it was too much so we settled for wood.

Everything that is coloured is painted and permanent, if you watch this vid from about 30 secs in you can see that we also have some black and white thick rubber strips that can be moved to create different layouts, they're very heavy and if heavily hit by a car only tend to move 12" or so;
+ YouTube Video
ERROR: If you can see this, then YouTube is down or you don't have Flash installed.


Just in case you're wondering, I'm on the committee at WLRC and I'm one of the peeps who painted it all

Painting is a tedious pain, but the end result is definitely worth it

As for the red and white paint, our main track maintenance guy actually phoned Silverstone F1 race circuits track maintenace dept. and asked what they used for the real curbs

Chlorinated rubber based road lining paint, 60 per 5litre can in the UK

Apparently the manufacture in the US is Unitas.

The main green sections and the red around the outside of the circuit are simply water based paints, much cheaper and seem to last well, it's the area's that get hit that need a lot of high impact paint on them.

Skid...

So are the concrete curbes poored right onto the asphalt? Or are they formed somewhere else, and then just layed out onto track? If that concrete is permanent... how often is the entire thing redone for an entirely new layout?

Thanks for the info.. keep it coming!

The original curbs (underneath the ones you can see which we did last year) were poured/formed in place, and lasted over 20 years.
The main layout hasn't changed over that time, we just use the rubber strips to change the layouts to the following (the Full GP is used for all big events) club meetings use whichever we want;

Sorry for the tedious questions, but appreciate your time here! More questions... so the concrete, how is it shaped / formed right there on the track? The only concrete experience I have is with forms built with wood...

do you let it semi-dry... then just plop it down and shape it with your hands? Then grind it smooth? then paint? something like that? Or is there a practice/technique I am completely ignorant to?

Any info on this?

The cement etc is just mixed to be fairly sludgy, so when put down it doesn't just want to 'run out' over the track, then you can shape it using the same tools as used when plastering a wall. Shuttering is better for any long straight bits etc.

Another question, what technique did you use to get the white boarder paint stripes so clean? They look like they were painted by a machine, they are so straight.

(oh and by the way, iv watched that video at least a hundred times )

No, shuttering is using a couple of bits of wood like a mold to pour cement or concrete into.

The white lines were marked out using a long chalk line marker;
+ YouTube Video
ERROR: If you can see this, then YouTube is down or you don't have Flash installed.

Once we had the chalk lines down it was a case of masking either side with duct tape, then slapping a load of the white paint down. Our lines were 4" wide, standard road line painting width

For the outside corner white lines you just have to try a take a few measurements from the corner apex's to build up a rough idea of where the white line should be, then repeat the above

The black and white finish line chequer was a stencil we made up of several of the rectangles, then we sprayed the stencil with acrylic line paint which dries in a couple of minutes. Did all the black rectangles, then did the same with all the white.

Have you guys tried road rails? They make for a nice layout when you can't use a permanent concrete curb option.
