A flexible mat system, including a plurality of base platforms, each respective base platform having a first pattern of phase transforming columns and voids extending from a respective flat member, and a plurality of plane-engaging runway platforms, each respective plane-engaging runway platform having a second, reversed pattern of phase transforming columns and voids extending from a respective flat member such that each respective plane-engaging runway platform is lockingly engagable to a respective base platform to yield a landing segment with parallel top and bottom flat members. Each respective base platform is an aluminum/steel composite. Each respective phase transforming column is further comprised of a plurality of stacked operationally connected phase transforming cellular members. Each respective cell further comprises six hexagonally spaced support members defining six hexagonally arrayed sides, with two opposing sides define x-shaped struts extending between adjacent support members. Remaining sides define parallel struts extending between adjacent support members. Each respective phase transforming cellular member can shift from a first stable configuration to a second stable configuration in response to an applied load.

An impact-absorbing assembly includes a covering layer being one or more of artificial turf, rubber mats, polymer mats, short pile carpeting, particulate infill, wood chips, and ground rubber chips. Also included is a layer of underlayment panels positioned beneath the covering layer. The panels have a panel section with a plurality of drain holes formed therethrough. A top surface of the panels is configured to support the covering layer. A bottom surface of the panels has a plurality of bottom projections that cooperate to define bottom channels suitable to permit water flow across the bottom surface, the bottom channels being in fluid communication with the panel drain holes. The bottom projections define a first spring rate characteristic that is part of a first stage and a second spring rate characteristic is part of a second stage, the first stage having a smaller volume of material than the second stage.

The invention relates to a paver supporting apparatus and generally includes a modular grid having a body and a plurality of planar adhesive receiving sections extending across a width thereof. The body includes a top surface, a bottom surface positioned opposite the top surface, a plurality of geometric lattices provided from a plurality of walls. The plurality of planar adhesive receiving sections are positioned between the geometric lattices and have a width greater than each of the plurality of walls.

The invention relates to a signaling system, comprising a crossable zone intended to be positioned on a highway and comprising a signaling marking forming a plurality of signaling strips, said system being characterized in that: The crossable zone comprises a plurality of photovoltaic zones (ZP) comprising photovoltaic cells (Cp) intended to capture light energy in order to convert it into electrical energy; The crossable zone comprises a plurality of signaling zones (ZS), of non-zero areas, so as to form said plurality of signaling strips, each signaling zone (ZS) incorporating electrical lighting means; A control system for controlling said electrical lighting means; At least one storage unit (14) for storing the electrical energy generated by each photovoltaic zone (ZP) and connected to said electrical lighting means in order to supply them with electrical energy.
