For all you guys and gals out there that want to throw in your two cents about track building, here's the time and place...
What we really need is knowledge on dust control on the clay surface, I have been digging around some of the flat track sites and this is what I came up with...
"you got good dirt and you got junk dirt. What we'll do is: water the track to put lots of moisture in; wheel pack it and run it in; then sweep the whole entire racetrack from top to bottom because there's a lot of rocks and debris from the weekly car show in the dirt. Then at 2pm the ag sprayer will come in and put dust control agent on top of the clean dirt and then we'll wheel pack it and run that in, and then these guys oughtta have a good race track the rest of the day."
"A. Each track we go to presents a unique challenge for us, because there’s different dirt in different parts of the country (for example, red clay in the South, sand in Florida, limestone in Ohio, black river bottom clay in Illinois and Texas) and naturally weather conditions vary from city to city and race to race. As Operations Manager for the series, I work closely with the regular track prep crew to prepare the track for race day. Here are the steps we generally follow:
1. We make the racing surface smooth to start with.
2. We spike it up to 3/4-inch to allow the water to get into the dirt.
3. We water the track to put as much moisture into the track as possible prior to race day.
4. On race day morning, we add a dust control agent such as calcium chloride.
5. Then we wheel-pack the surface to try to keep the moisture sealed in the track.
6. Finally, we water the track some more, to keep the top from drying out and becoming crusty (but try not to "rain the track out" with the water truck so the event can start on time).
We borrowed this process from the master of track prep, Rod Garrett of the Illinois Motorcycle Dealer Association, who has followed this process for years at Springfield with great success.
Since there’s no magic formula for preparing a race track, we need to rely on our experience and gut instinct. In Houston we used 1.7 gallons of liquid chloride per square yard, while at a different track we might use as much as 3 gallons per square yard. This mixture will change depending on the type of dirt at the facility, weather conditions, etc. And at times we may use flake chloride instead of liquid chloride based on what’s available at the time."
Sounds to me like the calcium chloride is one of the main keys. Our dirt section is nowhere near as big as a flat track but the same principle should apply.
We will also need help to pack the track. In a perfect world we would use one of those steam roller type rigs, if we could afford it. Last year we used our trucks, mine really seamed to work quite well with the wide tires and all, but I wore out my clutch slave cylinder, ended up costing me about $400. Needless to say I will not be using my truck for this again.
So the deal is, if we do not have control of the dust at anytime throughout the day it could be the end of our days at Tradex.
