400' x 20' "driveway"

ok so my RC club has a 400 foot by 20 foot runway thats asphalt

that has 2 issues
1. we have a big crack in the middle right on center line
2. it needs to be resurfaced

the crack is maybe 1/4" wide and the club has tried to fill it with all kinds of stupid stuff like sand etc (i think we may have a sinkhole under it)

the runway is old ~mid 70's and wasnt done very well i have been told it maybe as thick as 3 feet at parts

ideas?

Aside from filling the crack with concrete patching compound with a latex additive, there isn't any major long term fix you can do on this as a DIY

It's from the 70s? It looks like asphalt. That's a really good lifetime, even if there is no car traffic on it, the weather would eventually have made things worse.

I don't think you should worry much about it since you don't have any "real" planes that are going to land on that :P

these are "real" planes there just not "big" planes

the issue is small electric and some of the bigger aerobatic birds with small wheels dont like the crack and you end up with only 1/2 the runway to work with

and it just looks bad

oh and the club has the money to pay for what ever >.> just no one has a good plan that we know is going to work

so nothing ever gets done

at the lest it needs a new surface and be repainted

Why not call up a asphalt paving company, ask them to come take a look and quote a price to properly repair the crack?

My guess is that it will require cutting out the existing cracked section, digging out and compacting a proper base, then repaving the area.

Get bids from your local asphalt contractors. See if any have a 20' wide paving machine so you don't end up with a seam in the middle.

the big issue that stops any of this is making sure the crack doesnt come back

again one wants to spend the money only to have teh crack come back in 2 years

Which is why any fix applied just to the crack will never last long term. You don't build a house starting with the roof first, you build the basement upon firm ground. If the ground isn't firm, you dig down until it is.

Do they have enough money to pay for a CONCRETE runway?

But seriously, a paving company would know (Well, get several different opinions).

I'm thinking that if a latex based compound is applied to the crack, it would last a while since the compound would be able to stretch and compress.

But it's still an imperfection that could flip out a plane with tiny wheels.

Hah.. they even have a large RC plane coming in for a landing.

OT.. Have a professional quote you to properly strip and resurface the landing strip.

As stated by others DYI repairs are going to only last a short time. That section needs to be cut out and then a new base install properly before the asphalt is applied. Overall considering the age it actually looks quite good.

Be glad you have any runway at all. This is our R/C aircraft field - »goo.gl/maps/7Txq

And what's with all the fencing at your field?

sarcasm It's so the TSA can do proper screening. How pray tell can you have any security without a fence?! Didn't you see the 2" high screeners in the grass? /sarcasm

Have you thought about making a sheet metal "plate" to cover the crack?
If you get a strip of 16-18Ga galvanized steel about 8" wide and however long and lay it over the crack and fasten it down with a good calk the planes should roll over it with no issue.
The 8" of course would straddle the crack, 4" on either side, and since 8' is a common length, 5 pieces should cover the 40' width.

Sheet metal should be strong enough for any reasonable load, except full size aircraft. This method would have the advantage of allowing the crack to expand and contract due to temperature changes on the pavement.

I have a similar crack in my driveway where two sections of pavement join. Over the years I have tried everything I can think of to repair and stabilize the crack. No luck. Of course since I drive cars over my pavement, a sheet metal bridge would not work.

hmm i like this idea ill run it by my club next meeting
most models are under 50lbs even the big 1/3 scale stuff

is there any easy way the plate could be put grade to the surface?

the issue is mostly jets that need long take offs in the summer and long roll outs but have small wheels for there size

16 gauge sheet metal is 1/8" thick so you would have to figure out a way to recess it smoothly. Sheet metal comes 10' lengths.

If 0.059" is too big a bump, go with 22 or 24 ga. It does not have to support any serious weight, just stay flat.

Heck, I bet there is more than 1/16" in surface imperfections on the asphalt on the good part of the runway.

It may be possible to get the shop that shears it to hit it with a sander and break the edge so it has a little more lead in and smoother on the tires.

could a new surface be put on top of the whole thing + the metal sheet?

Basically that is an expansion crack. It is going to enlarge and contract with temperature.

Actually I believe 16 ga is about 1/16" thick or, as per ASTM A 569, 0.059. Galvanized, ASTM A 526, is a little thicker being about 0.0635".
