Method for slowing an aircraft using a foamed glass composite runway
A method of slowing an aircraft overrunning a runway, including covering an area adjacent a runway with irregular foamed glass bodies having aspect ratios of about 1:1.9 and diameters of about 10 mm to about 80 mm to define a bed, pouring liquid cement over the foamed glass bodies such that the cement infiltrates at least through the bed, curing the liquid cement to define a composite material of foamed glass bodies in a cementitious matrix, and crushing at least a portion of the composite material with an oncoming aircraft, slowing the aircraft. The composite material is at least 85 volume percent foamed glass bodies. When pouring the cement, the liquid cement flows over and around the foamed glass bodies. The aggregate bodies crush and break up before slip failure occurs when being overrun by an aircraft. The aggregate bodies intersect to define stacking angles of about 35 degrees. The cementitious matrix has a cementitious surface.
