View Full Version : MRA Board Surveys New Track Surface at Pueblo 6/25/12

MRA members,

In response to concerns raised about the new surface and the new Turn 10 configuration at Pueblo Motorsports Park Tony Baker, Jim Wilson, Ray Gaimara, Shannon Moham and I drove to PMP this afternoon to put our own eyes (and feet) on it to survey the conditions.

We were greeted by the track manager, Jason, and he gave us a tour of the new configuration. During the tour we were able to identify some points of concern and come up with solutions to mitigate those concerns. The primary concern was the level of traction crossing the new concrete that was installed for the burnout boxes. Much as we have experienced before at Pueblo, the current situation offers varying levels of traction as you cross the track on the line. Jason has agreed to run additional rubber into the track across the surface to equalize the traction level.

The new shape at T10 dramatically changes the corner. It is a much more square corner than it's been in the past and the speed at the apex should be much lower. The run into the corner will be a heavier braking zone than it's been in the past.

There are some additional barriers around T10 that will require protection. Ray has evaluated this area and has a plan for protecting it.

The track entry lane has been repaved. While it remains narrow, the big bump at the end is gone and it's smooth.

The pre-grid / hot pit area has been repaved

The balance of the track looks very good. The asphalt work is smooth and well executed. All of my reference points (patches in the asphalt) for T1 are gone and the corner looks positively wide. T2 and T3 and T4 remain as you remember them, with the exception of the smooth asphalt. The bump and patch at T5 are gone and it is now smooth. The cars have already done a small amount of damage at T7, but even with damage it is considerably better than the previous condition of the entire track.

The curbing at T9 has been replaced with a much more conventional racing curb instead of the tall concrete block that was there in the past.

The only other area of note is a drainage run that has been cut across the track near the entry to T9. There is some damage to this patch already and Jason has agreed to use some Rhino Patch to fill the damaged area and smooth out the transition.

In conclusion - Pueblo has always been a compromised roadracing course due to the conflict between the requirements of drag racing and roadracing. This is more evident to us as motorcycle racers than it is to those who race cars. While some of those compromises remain, the track as a whole is in better condition today than it was a year ago. It still presents some challenges to us, but we feel that our concerns have been heard and will be addressed before the race weekend.

Should you have any questions please feel free to contact one of us.

Thanks for the writeup guys. I knew from the pictures it was goign to slow the corner down quite a bit. How is the transistion from the asphalt to concrete to asphalt? When you say slick how slick is it? That is the new burnout box correct?

Since all the markers are gone entrering turn 10 are we going to use a few cones? Or did I misunderstand...

What fridays practice is like vs Saturday morning after the trags is going to be much different in turn 10 I'm guessing...

Thanks in advance :D

The transition is completely smooth now - at least on foot... ;)

Once the entire burnout box and drag lanes are "covered" in rubber, there should be little discernable difference in traction compared to the old course. 1/2 of rubber is a 1/2 of rubber, regardless of the underlying surface.

Right now there is about 2' of "smooth" concrete on either side of the burnout boxes and drag lanes that has NO rubber on it at all. It is VERY slick. Jason will cover those in rubber before our event.

So we will be either on asphalt entering the turn (good traction), rubberized concrete exiting the turn and almost to start finish (mediocre traction, but ultimately same as before), and there is some "brushed concrete" on the far sides of the lanes and in the middle between the lanes (good traction). Depending on your line you may cross the brushed concrete between the two drag lanes but it will be quick over it. I'll send Wilson some pix as he's smart enough to post them here...

Did anyone ride it, or were you guys on foot mostly?

Erik Peat and Dave Martynowski rode it in the morning and alerted us to the concern. That's why we drove down - this not a planned visit.

You will see in the pix the difference between the surfaces, and I can speak to the corrective actions required.

We will be deploying airfence in all areas of concern thru Turn 10 as always.

So where it is black there is traction, and where it is white there is none?

The white in the middle and edges of the track is not polished concrete.

Dave,

There are three distinct colors in the last photo above. Bright white, black, and a darker white/grey between the two.

The spots that are bright white are brushed concrete and offer good traction. The black is rubber on the smooth concrete and offers traction roughly on par with what we are used to in that spot at Pueblo. It's the darker white/ grey that is the problem as it is smooth concrete and offers very little traction. These are the areas that the track management will be running the burnout machine over to put a layer of rubber on before our event.

Thanks for all the details everyone.

props to the board for going down ahead of time and working on some solutions.
