Abstract:
An electrically groundable, reusable, load-supporting surface includes a plurality of planar mats and a plurality of removable, electrically-conductive covers. At least one cover is configured to be coupled to each respective mat. Each cover includes at least one mesh portion constructed at least partially of electrically conductive material. The respective covers of adjacent mats in the load-supporting surface are configured to be electrically interconnected. At least one grounding rod is electrically connectable between at least one cover and the earth to electrically ground the load supporting surface.
Abstract:
Apparatus for electrically connecting and grounding at least two mechanically interconnectable, planar mats in a reusable load-supporting surface includes at least one removable, electrically-conductive cover configured to be engaged with each mat and extend at least partially across the top and/or bottom face thereof. Each cover includes at least one conductive interface configured to electrically connect its associated mat with at least one other mat in the load-supporting surface.

Abstract:
A pavement interlayer, suitable for laying between layers of pavement, comprising: at least one layer (200) of interlayer material, a plurality of piezoelectric elements (202); at least one transmission line (203), coupled to the plurality of piezoelectric elements (202), for transmitting power generated by the plurality of piezoelectric elements (202) to an output.
Abstract:
A roadway segment includes a body having a length along a direction of travel, a width along a width axis, and top and bottom halves along a depth axis. The segment also includes a strain sensor array with one or more optical fiber cables embedded in the bottom half of the body. The strain sensor array includes vehicle-strain sensors configured to detect strain on the body resulting from vehicles traveling across the top surface. The segment also includes a processor that operates the plurality of vehicle-strain sensors at a resolution of not greater than one picometer (1 pm). Any segments of the optical fiber cable(s) that intersect are separated from one another depth wise by at least two-tenths of an inch (0.2 in.). Each of the sensors is separated from each other along the width axis by at least two inches (2 in.).
Abstract:
A modular cell that may be used with other cells to form a matrix under a load bearing feature, the cell being a single piece molding that supports a compressive load placed thereon, the molding including a void space defined within: a skirt shaped support member defining a substantially planar surface with an opening therein; and at least one leg integral to and extending from the support member. The cell further includes at least one separate linking member that releasably links together multiple cells to form a matrix of cells. The cells may be linked together vertically and/or horizontally. The cell and matrix include greater load bearing capacity and rigidity through aligned legs to carry the weight as well as interlinking members that act to share the load among the various cells. The design also requires less material hence is cheaper to produce. The void space is also easily accessed hence allowing for easy access, filling and laying of utility lines where needed.

Abstract:
A support surface (112) configured to be electrically connected to at least one other support surface and deployed on or near the earth's surface includes a mat (26) having top and bottom surfaces. An electrically-conductive cover (110) extends at least partially across the top surface of the mat. At least one electrically-conductive interface (138) is associated with the electrically-conductive cover. The support surface also comprises at least one electrically-conductive metallic band (188) which, in connection with the electrically-conductive interface, is configured to facilitate electrical connection of the electrically-conductive cover to at least one other support surface.
