How long does an airport runway usually last?

Major airports typically build runways to last between 20-30 years before needing to be fully rehabilitated (though it doesn’t always work out that way). A runway rehab is effectively a reconstruction of the pavement and can be done two different ways. One way is to completely close the runway to air traffic while the pavement is rehabbed.

How big of a runway do you need for heavy aircraft?

Pavement thickness varies from airport to airport, with commercial airports serving heavy aircraft having runway surfaces with a thickness between 10 inches and 4 ft., including the subgrade. Once the runway surface has been paved, it is grooved to allow for water to drain, minimizing the risk of aircraft hydroplaning following heavy rain.
