How often do they repave runways?
They often will triple the normal number of repaving crews and equipment and attempt to complete the job in a single 24–36 hour period. It depends on the quality of materials and condition of the exististing surface and length of runway. Time of year and weather are calculated.
How long is the longest airplane runway?

Runways are taken out of service to receive major maintenance roughly once every seven years. Each of these rounds of maintenance takes up to ten consecutive weeks to complete. During those weeks, parts of the runway are repaved and entire systems are replaced.
How thick is the tarmac on a runway?
For heavy-duty commercial aircraft, the pavement thickness, no matter what the top surface, varies from 10 in (250 mm) to 4 ft (1 m), including subgrade.
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.
Do you have to use the active runway?
Selection of the active runway, however, depends on a number of factors. At a non-towered airport, pilots usually select the runway most nearly aligned with the wind, but they are not obliged to use that particular runway.
How long is the runway at Lord Howe Island?
