A method of forming a vehicle arresting system includes installing a plurality of stratified layers of aggregate and compressing each layer prior to adding a next aggregate layer, a slab layer, and/or some other separation layer. In one aspect, one or more of the aggregate layers comprises a glass foam, and one or more of the slab layers comprises a cementitious material having an oven-dry density of 100 lb/ft3 or less, such as cellular concrete. The aggregate layers may be poured to approximately the same depth as one another, or at least one aggregate layer may have a different depth than the other aggregate layers. Similarly, the method of compaction for one aggregate layer may be the same as or different from the method used for the other aggregate layers.

Engineered material arresting system and methods for forming same

A vehicle arresting system includes a base layer comprising a crushable aggregate and a cover layer comprising a cementitious material having an oven-dry density of 100 lb/ft3 or less. The system also may include an arrestor bed and a plurality of anchors. Each anchor includes a support rod coupled to an associated puck, each support rod being secured to a foundation that supports the arrestor bed, and each puck being embedded in the cover layer slab of the arrestor bed. Additionally, each support rod is coupled to its associated puck via a shear link breakable at a predetermined load. A method for arresting a vehicle includes depositing a base layer on a region where the vehicle is to be arrested, the base layer comprising an aggregate, and depositing a cover layer over the base layer, the cover layer including a cementitious material having an oven-dry density of 100 lb/ft3 or less.
