A heatable module for use in constructing a pathway for traffic comprises a base member having a perimeter edge. A top plate is securable to the base member in overlying relation to the top surface of the base member. An electrically powerable heater member retained by at least one of the base member and the top plate. To form a heatable pathway for traffic, the modules are placed in perimeter-edge-to-perimeter-edge relation one to the next.

A heatable pathway system for traffic comprises a first module having a first electrically powerable heater member and a second module having a second electrically powerable heater member. The first module and the second module are each installable in place to form a heatable pathway system for traffic. An electrical power controller circuit has a first power output connected in power supplying relation to the first electrically powered heater member and a second power output connected in power supplying relation to the second electrically powerable heater member. The electrical power controller circuit is operable to provide electrical power from the power outputs in a heating cycle that comprises a first heating sub-cycle and a second heating sub-cycle such that, during a heating cycle, a first one of the electrically powerable heater members is on and a second one of the electrically powerable heater members is off during the first heating sub-cycle, and the second electrically powerable heater member is on and the first electrically powerable heater members is off during the second heating sub-cycle.

A multifunctional synthetic resin block for roads. The synthetic resin block includes a water permeable sheet configured as a synthetic resin block having a flat sheet shape so as to be laid on a ground, a block frame configured as a synthetic resin body taking a form of a rectangular frame, which is divided into multiple rectangular areas each having open top and bottom sides, so as to be installed on the upper surface of the water permeable sheet, the rectangular areas being filled with filler stones, and multiple corrugated plates each configured as a synthetic resin having a rectangular plate shape and arranged so that corrugations thereof are oriented perpendicular to each other so as to cover the rectangular areas of the block frame. The synthetic resin block provides almost all functions, such as a rainwater retention function, water permeation function, and anti-slippage function, at low cost.

A timber access mat having an electrical grounding feature includes an electrically conductive cover layer that is removably carried over the top of the body of the timber access mat. The electrically conductive cover layer can be formed from one or more sheets of expanded metal such as expanded steel. The layer is joined to a perimeter frame that includes offset connector tabs that allow mats to be positioned side-by-side. The connector tabs are paired with cable guides to protect the cable leads that connect the mats. The perimeter frame and conductive cover layer can be added to traditional timber access mats when electrical grounding is required and then removed and stored when not required.

A roadway track (10) for a vehicle (T) is provided, the roadway track having a roadway face and being suitable for being rolled up and designed to be placed on the ground and presenting a rolled-up position and a deployed position in which the roadway track extends substantially parallel to the ground. The roadway track includes at least a first track portion (14) and a second track portion (16), the first and second track portions being connected to each other by a pivot connection (18) having a pivot axis (A) that extends in a direction that is substantially perpendicular to the roadway face, whereby the first track portion can pivot relative to the second track portion about the pivot axis so as to form a bend (V).

One aspect of the invention provides an extruded, polymeric underlayment pad including: a substrate; a first plurality of at least four intersecting ridges extending perpendicularly from a first side of the substrate; and a second plurality of at least four intersecting ridges extending from a second side of the extruded polymeric substrate.

A lightweight universal panel mat made of plastic or elastomeric material and having a first section that provides a relatively flat, textured or structured top surface to facilitate movement over the upper surface and a second section having geometry that includes a plurality of cells having top surfaces that support the first section. The mats also include first, second, third and fourth sides forming a perimeter of the mat, wherein the first and second sides include upper structures having a sloped lower surface and the third and fourth sides include lower structures having sloped upper surfaces. The sloped surfaces are configured to allow for overlapping with sloped surfaces other like mats for interlocking therewith while forming a generally flat continuous top and bottom surface of the overlapped mats. The mats may be interlocked by a fastening member which fits in aligned openings of the adjacent mats for connection therewith.

A composite mat comprises a plurality of layers each comprising a plurality of elongate members extending parallel to one another and transversely to the elongate members forming the adjacent layer. Thus, each member of a first layer spans across the members of a second layer such that each member of the first layer intersects each one of the members of the second layer at respective intersecting locations. Each elongate member is formed from pultruded composite material defining a tubular body which encloses a longitudinal axis of the respective member. The tubular body has on its outside an opposing pair of wide faces and an opposing pair of narrow faces. The tubular body includes an interior cavity in which there is provided a reinforcing rib bridging the cavity in a direction from one wide face to the opposite one so as to resist compression of the body in this direction.

The present set of inventions relates to the field of building and in particular to building constructions and to processes for manufacturing building constructions comprising tensioned and non-tensioned tendons and can be used to construct residential, public and office buildings and constructions as well as for reconditioning or restoring the same. The technical result consists of the provision of relatively long-extended constructions or complicated shape constructions working as a single pre-tensioned construction and characterized by high carrying capacity, stability and rigidity. Said technical result is obtained by the fact that in a multi-component building member comprising at least two components and pre-tensioned tendons, each component is made as a tendons module comprising an initial and a final supporting elements with holes for the pre-tensioned tendons and with a stand for placing anchors and tensioning arrangements; and a reinforcing cage located between said supporting elements and comprising an upper and a lower elements in the form of a grid with a cellular structure, the cells having the shape of an equilateral polyhedron, and at least one median element under the form of a space reinforcement structure comprising inclined reinforcement bars forming equilateral polyhedral pyramids oppositely oriented in space, the pre-tensioned tendons of the first component being anchored at the initial and final supporting elements of the same, the pre-tensioned tendons of each following component being anchored at the final elements of the previous and the current components. Said technical result is obtained as well by the fact that in a process for assembling the multi-component building member, the median, the upper and the lower components of the tendons module are preassembled, attached between the initial and the final supporting elements, the tendons are inserted and then pre-tensioned, wherein, starting with the second tendons module of the construction, the anchor of the pre-tensioned tendons is mounted on the final supporting element of the previous tendons module, whereas a tensioning arrangement is mounted on the final supporting element of the pre-tensioned tendons module.
