Abstract: A multi-axial geogrid possesses a series of interconnected strands or ribs that are arranged along at least two different axes within the plane of the structure. The strands or ribs have an aspect ratio, defined as the ratio of the thickness to width, of greater than 1.0, thickness being the direction normal to the plane of the structure. The geogrid can be manufactured by modifying the process parameters in order to create high aspect ratio ribs, using any of the various known methods for producing geogrids. A reinforced civil engineering structure, and method therefor, is formed by embedding in soil one or more horizontal layers of geogrid having high aspect ratio ribs. The reinforced structure shows improved rutting performance when subjected to vehicular traffic.

Abstract: 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.

Abstract: Various implementations include a machine for resurface existing roads. 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.

Abstract: The present invention is directed to a multi-axial fabric which is dimensionally-stabilized. The composite fabric has a substrate and a plurality of first, second, third, and fourth strands disposed across the substrate and oriented in non-parallel directions with respect to one another. Binding fiber secures the aforementioned strands to the substrate. The composite fabric can be substantially free of more than three strands overlapping at a common position on the substrate. A road employing the multi-axial fabric is described.

Abstract: 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.

The access port is operable to improve access to components of the paving system prior to, during, and/or after installation. The paving apparatus further includes a removable fastener for improving removability and serviceability. The removable fastener attaches the paving apparatus to its neighboring structures to form a paving surface, may be disengaged from the neighboring structures for removal, repair and/or service of the paving apparatus, and may be re-engaged upon re-installation of the paving apparatus.
