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 fabric (10, 20, 30) adapted for the reinforcement of constructions such as of roads or pavements has a fabric width W2 in a transverse direction. The fabric (10, 20, 30) comprises a carrier (12, 22, 32). The fabric further comprises reinforcement elements (14, 24, 24, 34) extending over the fabric width and being fixed or bound to the carrier (12, 22, 32). The carrier (12, 22, 32) has a carrier width W1 that is smaller than the fabric width W2 so that the reinforcement elements (14, 24, 24, 34) protrude out of the carrier (12, 22, 32). The advantage is that when two neighbouring fabrics (40, 44) overlap, it is possible to avoid a double layer of carriers.

A method for making a reinforced concrete structure and reinforcement agents are provided. In some embodiments, the method includes obtaining a mold for the reinforced concrete structure. A lattice is formed within the mold, where the lattice includes inter-locking ringed fibers and where each inter-locking ringed fiber is a fiber formed into a ringed structure that is inter-locked with at least one neighboring inter-locking ringed fiber in the lattice. The lattice is then encased by filling the mold with concrete. In some embodiments, the reinforcement agents are a plurality of ringed fiber-structures, each of which is coiled into a ringed structure that may or may not inter-lock with at least one neighboring ringed fiber(s)-structure.

A machine for resurface existing roads is disclosed. The machine may include a premixed stress absorbing membrane interlayer (SAMI) material distribution component configured to distribute a premixed SAMI material on an existing road. The distributed premixed SAMI material may include a mixture and/or combination of binding material and pre-cut fiber material. The machine may also include a channel positioned adjacent and downstream of the premixed SAMI material distribution component. The channel may be configured to supply an asphalt mixture directly over the premixed SAMI material. Additionally, the machine may include a screed positioned adjacent the channel The screed may be positioned to contact the asphalt mixture.

A millable, recyclable, paving fabric interlayer system for the construction and repair of roadways and other load-bearing surfaces and method of using such a fabric is disclosed. The paving fabric includes thermoplastic materials and is combined with asphalt cement to provide a flexible, stress relieving, waterproofing layer for roadways. Because of the thickness and asphalt cement absorption of the fabric, the system provides a stress absorbing interlayer to resist fatigue and reflective cracking in pavements. The system also acts as an effective moisture barrier due to the enhanced capability to retain sufficient asphalt cement when paved onto a roadway. Such a system has the required strength and elongation to be installed on smooth or milled surfaces yet is easily milled and recycled owing to the uniquely engineered tensile and tear strengths of the fabric.

A reinforcing fabric is provided. The reinforcing fabric includes at least one glass fiber, wherein the at least one glass fiber includes a binder, the binder including a polymer resin and a filler, the filler including a recycled asphalt shingle. Further included is a method of reinforcing pavement with the aforementioned reinforcing fabric.

A system for metering reinforcing aramid fibers into an asphalt mixer includes a vertical feed chute with straight walls that spans substantially a full diameter and a full length of a horizontal feed auger to feed bulk fibrous material by gravity from the feed chute in a radial direction along the length of the feed auger. The feed auger is rotated at a controlled rate proportionally to the rate of production of an asphalt and mineral aggregate mixture. A pneumatic conveying line conveys the reinforcing fibers from an outlet end of the feed auger to an asphalt mixer for mixing with the asphalt and mineral aggregate to produce a fiber reinforced asphalt concrete with an accurately proportioned amount of fiber dispersed therein.

A ground cover mat includes a slab that encases a core assembly. The slab is made of a rubber material and defines a lower major surface and an upper major surface of the ground cover mat. The core assembly comprises horizontally extending boards, which may be made of wood, disposed in horizontally spaced apart, side-by-side relation with each other. The core assembly further comprises a rebar mesh, which may be made of steel, that is disposed on top of and in contact with the boards.
