pende_tim posted : I have a similar crack in my driveway where I stopped paving and resumed a year later.
When the driveway was completed the following year, the contractor cut the end of last years job, applied tack oil, and started paving again.

All was well for a year then due to this being a weak spot and the heating/cooling/expanding/contracting a crack opened up in a year or so.

The problem with continuing an asphalt paving job after a delay is that the edges never knit into a monolith like the original hot rolled section.

I suspect this may have been what happened here. Half of the runway was paved and rolled and a while later after the first section cured, the rest was done. The second section did not knit to the first piece and over time, the crack has grown.

In any case, the chances of repairing this crack permanently are slim to none unless you can get a 100% bond between the sections which with set asphalt is not possible.

You can fill it and it will be good for a few months, but once heat/cold causes the asphalt to expand/contract it will open up again.

Put a bridge plate over the gap and enjoy the runway.

Pacrat posted : Considering the heat-spell we've been experiencing, it might be thermal expansion that is causing the crack. Rent a diamond saw, cut out the cracked section and repave just that area. It's a runway for model R/C aircraft, not a load-bearing highway. Cut it straight across, remove 3-4" of the asphalt, and Quickcrete the remaining gap, or use "cold patch" and tamp it in evenly. You're just trying to restore a smooth surface... not bringing it up to highway construction codes.

as far as i know they just dumped the asphalt right on the dirt
but id have to ask the older guys in the club

I suggest you dig right next to the asphalt in the cracked part to see what's underneath and how deep it goes. It may help explain the origin of the crack which looks unusual in what otherwise seems to be good pavement from the looks on the video and the aerial view in Google Maps. If you don't know the origin of the crack and how to stabilize or eliminate it nothing you do will solve the problem permanently.

I also considered it could be a fault line but in the aerial view I cannot see any similar cracks in nearby roadways.

printscreen posted : This is very strange for a purely expansion crack. Too straight and perpendicular to the long axis of the runway and seems to be right in the middle. By any chance, is there a concrete base deep beneath the asphalt and could that be a construction joint of such concrete base? If that is the case you will need to stabilize this joint first before atempting anything.

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".

pende_tim posted : 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.

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

pende_tim posted : 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.

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

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.

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.

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.

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.

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?
