Concrete or Asphalt - What's the difference in the game?

[geozero]

Other than the look, what is the difference between concrete and asphalt in the game?

[Agathorn (SH)]

Durability. Grass wears faster than concrete which wears faster than asphalt.

[geozero]

Concrete wears out faster than asphalt? Shouldn't that be the other way? Asphalt is softer than concrete.

[AngerIsAnEnergy]

Do any of them affect the taxiing speed?

Or is taxiing speed fixed?

[Agathorn (SH)]

What is broken about it? I haven't noticed any difference in speed by material type, but then I haven't really looked that closely.

From Engineering point: Concrete is the best pavement to build with (In real life). Concrete will last 20 - 50 years with very little maintenance. Normally used there where the aircrafts are parked for long periods of time. If it was not for the high expense and high pollution, concrete would have been used on all airports for runways and parking pays alike.

Asphalt is much much much cheaper to build but needs maintanance regularly. It does not handle static (parked planes) loads over long periods well.

Thus airports are build with runways with asphalt and airplane parking bays with concrete.

I would LOVE to see this implementation in the game.

What? In what universe is asphalt more durable than concrete?

[Stellie_Boyz]

Thanks, but thats wrong. I am a civil enginer and that is not true in reality. Concrete is far superior to asphalt. Concrete is at least twice more durible than aspalt but asphalt 3 times cheaper than concrete.

Airports are designed as follows: Static loads are carried by conrete and asphalt carries the dinamic loads. Thus runways and carryways are asphalt and the parkbays are all concrete.

But thanks for letting me know. I hope they implement something more logical in the game in the future.

In the game asphalt and concrete have the same durability
In real life Concrete is way stronger than asphalt
They will probably change durability or make it more noticeable soon

[geozero]

That's why I asked... just doesn't make any sense.

[Nickjet45]

I get what you're saying lol, but for now just base everything on price :)

Thanks, very useful information. Will look into how we can alter the cost and durability values for a more realistic approach.

[Silverbiker]

Asphalt is used on runways (high speeds 80+ knots plus impact of wieght of aircraft) for the fact that it has superior grip esp when wet but they need regular inspection usually at night when there is no traffic
As grip is not as important on taxiways (low speeds approx 25-30 knots) concrete is used for lower maimtenance costs

Asphalt surfaces are also much easier to resurface/replace compared to concrete, hence why most roads are surfaced in asphalt.

Don't know about taxiways, if they are made of concrete often or asphalt as they are used mostly in a dynamic way and not for parking?

But I have to do them in concrete anyway (*), because the empty asphalt tiles are missing ... they only exist in concrete. Hope they will get added soon.


(*) Thats because I'm doing taxiways 3 tiles wide with an additional empty concrete tile on each side.

Taxiways are not meant for long term parking; that's what static stands and aprons are for.
