A modular pavement slab comprises a body, a strain sensor array, and a sensor processor. The body includes a top surface, a bottom surface, and four side surfaces. The modular pavement slab is configured to be coupled to at least one other modular pavement slab via connectors along at least one of the side surfaces. The strain sensor array is retained within the body and is configured to detect a plurality of strains on the body resulting from vehicular traffic across the top surface of the body. The sensor processor is in communication with the strain sensor array. The sensor processor is configured to communicate input signals to the strain sensor array, receive output signals from the strain sensor array, and determine a plurality of time-varying strain values, each strain value indicating a strain experienced over time by a successive one of a plurality of regions of the body.

Some deck or patio areas constructed of pavers mounted on adjustable pedestal supports must remain snow and ice free on their top surfaces. The pedestal-mounted paver heating system is designed to allow easy installation of electric heating cable that is positioned against the bottom surface of pavers so that heat generated by the cable is efficiently transferred up into the pavers to raise their temperature enough to prevent the accumulation of snow and ice on their top surfaces.

A method for repairing/treating a pavement with the use of a rheology modifier is disclosed. The method comprises first applying a layer of a rheology modifier composition comprising a rejuvenating component onto the top surface of the pavement that needs repair, then applying a second layer of a binder onto the rheology modifier layer. The second layer of binder effectively seals the rheology modifier layer with the rejuvenating component for intimate contact with the top pavement surface, thus penetrating the surface layer to extend the life of the pavement surface, arresting the deterioration of visco-elastic properties and restoring some of those properties.

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.

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.).
