A problem with unpaved roads is that they can be prone to damage when driven on. The road surface matting includes a first mat 1a and a second mat 1b, each mat having a series of substantially parallel beams 2, a plurality of spine rods 3 that run substantially perpendicular to and through the beams and connect the beams to one another. Each mat also has a joiner 7 adjacent an edge of the mat, arranged so that one of the spine rods passes through the joiner. The matting is such that the first and second mats are connected to one another by way of a connecting rod 8 that passes through and joiner 8 of one mat and the joiner 8 of the other mat.

A system and method for the construction of a hemp mat having consistent density whereby the hemp fiber mat may be used to strengthen ice or other entities for any number of applications and different types of construction designed such that it may be sturdy enough to stay bonded when it is transported, unrolled, and soaked during ice road construction but loose enough to break apart during spring to reduce blockage and environmental damage to the waterway on which the ice road was constructed.

A mat comprising a first side and a second side opposite the first side is disclosed. The mat has a body with a thickness defined between the first side and the second side and a width defined between a first edge and a second edge. A plurality of fortifying members can be positioned between the first side and the second side extend within the body substantially vertically with respect to the width. A lip can extend from the body of the mat and have a first rib having a first rib thickness. A first channel portion can have a first channel thickness whereby the first rib thickness is greater than the first channel thickness.

A structural reinforced composite construction mat includes a plurality of composite plastic beams that are ganged together to define the mat, with a plurality of flitch plates disposed between at least some of the plastic beams to provide additional strength and rigidity to the mat. The plastic beams may be made of a composite material have a generally rectangular cross-section. The flitch plates have a width (vertical height) when disposed between adjacent beams that is less than the width (vertical height) of the beams, such that the flitch plates may be recessed below and above the top and bottom surfaces of the mat, respectively. A plurality of rods extend in the lateral direction through the beams and plates to compress the beams and plates against each. The flitch plates may be metal or fiber-reinforced resin and may further include slotted holes to allow the beams to retract lengthwise in response to environmental changes.

An access mat system and method of assembly is provided. An access mat system, comprising a plurality of wooden layers, the layers arranged in a stacked orientation. A plurality of blind holes bored in the plurality of wooden layers, the plurality of blind holes in one or more of the plurality of wooden layers positioned to correspond to the plurality of blind holes in one or more of the plurality of wooden layers and a plurality of biodegradable fasteners for insertion into the plurality of blind holes.

A device for setting up a level crossing for crossing a track section having two rails, comprising one or more mouldings forming at least one part of a traffic surface of the railway crossing across the rails, and at least one moulding holder fixable to one of the two rails, wherein the moulding(s) is/(are) detachably attachable to at least one of the two rails by means of the moulding holder, wherein the moulding holder comprises two holding clamps fixable to the rail in juxtaposition to each other on both sides of the rail, and wherein the two holding clamps can be braced to each other such as to clamp the rail foot between the two holding clamps.

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.
