It depends if they have had their Geritol or not that morning! Or one of us wins the lottery and donates $30,000.00 to the club, tax deductible of course and then we pave the sucker the right way.

I wonder if they are able to control access to the site to prevent drag racing on the runway? It is hard to believe that material is strong enough and the staples stable enough to hold the geotex in place during a full throttle pass.

I decided to find out a bit more about the geotextile durability relating to vehicles especially, and contacted the folks in Los Alamos, so I contacted them to find out if their field was well fenced to prevent vehicle use. Their reply is below:

our field is partially fenced off, but vehicles can still get to it.
ATVs and motorcycles are on the field several times a month. so far
they have not done any damage. i think the fabric is too slick for them
to really do much harm, and we staked it down really well. we wish we
could fence it off better, but the landlord wont really facilitate
that. overall the stuff has held up fine.

i even drive on it with my pickup truck when i am moving the drag over
the field, and it seems to be fine with it.

it is surprisingly durable.

good luck, and you are welcome to come see us sometime.

Good to know. I like the part about weeds not growing up through it.

I asked the Las Aalamos folks a few more question about the geotextile surface. One of the reasons I contacted them again was because our Mancos shale has lots of frost heave, and it also has tremendous shrink/swell characteristics which help to push some things out of the soil. My concern there is whether the staples would hold. They apparently do not have heavy duty clay soil to deal with but do have the frost heave issue. Here is the response.

"yes, our soil does get a lot of frost heave. the staples tended to come
up a bit, especially while the fabric was still shrinking. a quick work
party and 1/2 an our or so and you can knock them back in.

the fabric is porous, so i suppose that if there is a low spot that does
not drain, the water will tend to stay longer, but should eventually
evaporate.

the stuff will not be maintenance free. you will have to spend a little
time each year rolling the ground, weeding, re-setting stakes, and
repairing the rips. probably plan on one work session a year, maybe two
if the weeds get bad. overall, at least it is something a club can do,
unlike paving which takes a professional to maintain.

keep me posted."
