A structure for the reinforcement of pavements. The structure includes at least a first group of assemblies of grouped metal filaments. These assemblies of grouped metal filaments of said first group are oriented in a first direction in a mutual parallel or mutual substantially parallel position. The assemblies of grouped metal filaments of this first group are coupled to or integrated in a substrate having a non-metal material.

Mats and methods associated therewith are described. The mats include a main body defined by a plurality of sidewalls and two exterior surface walls opposing each other. The main body includes a pattern of internal walls that define internal voids within the main body. At least one primary structural support rib is arranged within the main body and extends between the two surface walls and from one of the plurality of side walls to another of the plurality of side walls. The at least one primary structural support rib traverses the internal voids defined by the pattern of internal walls.

A removable and serviceable paving apparatus including an access port for providing access to the interior of the slab. 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.

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.

A method for installing hot asphalt pavement includes heating an aggregate to a temperature of from about 350 F. to about 400 F. using an emitter comprising a birefringent material, the emitter generating electromagnetic radiation having a wavelength of from 2 microns to 1 millimeter, wherein the aggregate is a recycled asphalt pavement; adding the aggregate to an asphalt in a mill to yield a mixture of aggregate with baked-on asphalt; laying the mixture down over a base to form a first layer of lift; and compacting the first layer.
