Abstract:
A mat that includes first and second side beams, a core structure located between and connected to the side beams, with the support structure including longitudinal members and having a height that is less than that of the side beams, a plurality of joining rods that attach the side beams to the support structure, with the joining rods passing through the sides of the side beams and the sides of the longitudinal members of the support structure; one or more elongated members attached to the upper portion of the support structure to form with the beams the top surface of the mat, and one or more elongated members attached to the lower portion of the support structure to form with the beams the bottom surface of the mat. If desired, steel plates can be provided between the beams and longitudinal members to increase the strength and ruggedness of the mat.
Abstract:
A vehicle energy harvesting roadway is provided. The vehicle energy harvesting roadway includes a deformable driving surface that is longitudinally flexible and transversely stiff. The deformable driving surface is disposed between a passing vehicle and one or more transducers or one or more compressible hoses.
Abstract:
A paving system for paving or flooring includes a top layer of a plurality of paving elements, and an underlayment support layer of a polymeric material configured into panels. The panels are suitable to support the paving elements, the panels having a generally planar support surface.
Abstract:
A paving system for paving or flooring includes a top layer of a plurality of paving elements, and an underlayment support layer of a polymeric material configured into panels. The panels are suitable to support the paving elements, the panels having a generally planar support surface and a recovery characteristic such that a deformation from a concentrated compressive load applied for a short duration returns the support surface to a generally planar condition.
Abstract:
A system including a pavement module that includes a protective system against wear and tear of rigid support elements of interconnected modules that form a covering of a pavement, or impact absorbers that integrate or are coupled to the pavement modules. The system consists of a pavement module with an upper side and a wear-protective system consisting of a protective shoe.
Abstract:
The invention is directed to a photovoltaic multilayer laminate, to a method for preparing a photovoltaic multilayer laminate, to a method for preparing a photovoltaic roadway, and to a photovoltaic roadway. The photovoltaic multilayer laminate of the invention comprises multiple flexible photovoltaic foil elements laminated at least to a carrier layer comprising electrical interconnections for said flexible photovoltaic foil elements, wherein said multiple flexible photovoltaic elements are arranged transversely to the longitudinal direction of the laminate, wherein a stretchable or compressible space is provided between each pair of multiple flexible photovoltaic foil elements.
Abstract:
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.
Abstract:
An industrial mat that has a support core configured and arranged to support other components of the mat; and upper and lower layers that provide upper and lower surfaces of the mat and that protect the support core. The support core includes a frame of longitudinal side members, end members and cross members each of which is made of steel or a thermosetting plastic material. The frame can include wood, plastic or elastomeric internal members or materials to fill internal open areas of the frame, with the upper and lower layers and the sides and ends of the frame retaining the internal members or materials therein. The mat preferably includes lifting elements of D-shaped rings, O-shaped rings, chains, or cables attached to the upper or lower layer or the support core to provide certified overhead lifting of the mat for installation and reclamation thereof.
