Stabilized aggregates and other materials and structures for energy absorption
Materials and structures for absorbing energy. The materials and structures are well suited for arresting aircraft and other vehicles, although their purposes need not be so limited. Also detailed are packaging and other solutions for maintaining system integrity, especially (but not exclusively) when foam glass or other aggregate is employed and stabilizing the location of the aggregate is desired.
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.

Systems and methods for arresting aircraft. In specific embodiments, the systems and methods can be useful in arresting light aircraft because they typically do not have the weight to penetrate available EMAS systems. The system is generally provided as a structure having a suspended layer of energy absorbing material. A lower portion of the system can have a lower strength, used as a method to suspend an upper, stronger/more highly energy absorbent portion of the system.

Polymeric foam composite for vehicle arresting system
Embodiments of the present invention relate to composite materials for use as a vehicle arresting system (also referred to as an Engineered Material Arresting System (EMAS). Specific embodiments may use modified polymeric foams composites. The polymeric foams may include additives, coatings, combinations of both, or other features than render them useful for an EMAS. The polymeric foams may also have one or more modified surfaces that provide a protective crust. For example, the one or more surface may be modified by application of heat in order to help close the polymeric foam cells and/or to create an encapsulative surface. These features can provide enhanced weather resistance, fire resistance, moisture absorption, jet blast resistance, improve their energy absorbing properties, or other desired features.

C08J 9/34 - Chemical features in the manufacture of articles consisting of a foamed macromolecular core and a macromolecular surface layer having a higher density than the core
Embodiments of the present invention provide a core of individual components having properties such that a system assembled from the components absorbs the kinetic energy of a moving vehicle. The components may be interlocking components. The components may be manufactured of ceramic or polymeric composite or other materials that are strong enough to absorb the vehicle's energy and help stop the vehicle safely by the system's ability to crush or deform upon impact, and not so strong that it causes the vehicle to crumple against the barrier. In one particular embodiment, the components may be modified packing elements that are traditionally used in gas to liquid columns.

Embodiments of the present invention provide field test devices and methods for testing the compressive gradient strength of installed vehicle arresting systems, such as those installed on airport runways. Current methods of testing such arresting systems are conducted on sample materials in-house, and these methods are not applicable or useful when tests need to be conducted on currently-installed systems in the field.
