Rigid runways made of postensed celled concret for airports and highways

摘要

A postensed celled concrete runway for take off and landing of aircraft is described, also for racetracks, freeways and highways, characterized by a celled structure wherein each cell contains: nervures, a cell base and a cell cover that forms the surface of runway. A core composed of expanded polystyrene is located between the nervures, base and cover, such that the volume weight of the cells is less than subsoil density. The celled structure also contains a leveling means that acts over cells of the celled structure to allow the cells to move in an upward and downward direction so that the runway surface can be leveled when there are sunken areas on the ground.
