https://en.wikipedia.org/wiki/Asphalt_concrete

Decent runway concrete ought to withstand a short landing. The exhaust impinges at an oblique angle and the peak impact point is moving at whatever the landing speed is. RVLs will be tougher - maybe on good concrete but fuggetaboutit on your typical 3000 foot strip or road in Filthistan. VLs? AM-2 and lots of it, or pizza-oven concrete.
