The construction of runways is similar to that of roads, only that the materials used are strong in holding heavyweight. Airport constructions necessitate careful use of instructions during the construction of runways and taxiways. Many airports rely on manufactured materials, including concrete or a mixture of aggregates and binders. Furthermore, building runways entails using natural surfaces: grass, sand or salt, ice, and gravel. The selection of aircraft construction materials depends on indigenous ground conditions, the types of aircraft using the airport, or the cost associated with the facility. These factors are fundamental in determining the thickness of the runways.
The construction of aircraft runways must be constructed by individual runway design, based on the direction of the winds and aeronautical paths, and immediate terrain. Airstrips require that surface layers are according to the runway magnetic bearing with 360 representing north, 90 representing east, 180 representing south and 270 representing West. Consistent inspections do the assurance and maintenance of the aircraft runways Pavement preservation involves periodic restoration of the top wearing surface. The intermission between resurfacing varies with respect to the type of the pavements. The pavements reduce hydro planning due to heavy rains through channels away from the runway. Runways differ based on aircraft type as aircraft operating weights determine the thickness of airport surfaces, relying on other factors such as takeoff and landing flap determining the runway’s length.
Taxiway differs from runways primarily because it is a path along the ground which allows airplanes to travel from one place to another. Taxiways facilitate movements between parking areas and runaways, while runways are designed to provide sufficient space for an aircraft to land or take off. Taxiways are hence labeled in white or blue while runways are labeled in yellow. The runways are also improves to relay their magnetic heading.
