  • a first and most commonly used form of road “mat” made by bolting together three las ers of 2 inch X 8 inch oak or fir lumber to form a mat that is approximately 6 inches thick. This first mat contains between one hundred and two hundred vertically aligned 6 inch bolts.
  • a second road “mat” is made by bolting together sixteen 6 inches X 6 inches X 14 foot pine timbers. This second mat uses horizontally aligned four 8 foot long steel bolts.
  • a third road “mat” places the wood timbers within a steel frame.
  • a fourth, and least common form of road “mat” is made by extruding various "plastics” to form a mat.
  • This road mat provides a number of advantages, as will hereinafter be further described.
  • the road mat can be ground up and scattered on site. In some situations, the road mat can be left in place to decompose naturalh' at the end of its use, thereby eliminating the environmental disturbance associated with removal.
  • FIG. 1 is a perspective view of a road mat made of cross-oriented las ers of thin wood fibre compressed and bonded together by resins.
  • FIG. 2 is a side elevation view of the road mat illustrated in FIG. 1.
  • FIG. 3 is an exploded perspective view of the road mat illustrated in FIG. 1, made by using resin to glue together multiple las ers of wood fibre.
  • FIG. 4 is an exploded perspective view of the road mat illustrated in FIG. 1, made by using resin to glue together multiple las ers of sheeting formed by the process illustrated in FIG. 3.
  • road mat 10 has a bod ⁇ ' 12 which is preferably the size of all standard road mats which is six inches thick, eight feet wide and fourteen feet long. However, it will be appreciated that road mat 10 will remain functional in smaller sizes as long as body 12 is at least three inches thick, at least four feet wide and at least twelve feet long. It is preferred that road mat 10 be at least three inches thick in order to provide sufficient strength to support a motor vehicle. It is preferred that road mat 10 be at least four feet wide, so two road mats placed side by side can readily handle the wheel base of a motor vehicle. It is preferred that road mat 10 be at least twelve feet long, so as to accommodate the distance between a front axle and a rear axle on a motor vehicle.
  • road mat 10 ma ' also be made thicker, wider or longer than a standard road mat. For example, a road mat which was seven inches thick, twelve feet wide and twenty feet long would still be viable. An upper size limit is dictated by shipping, handling and manufacturing considerations.
  • road mat 10 ma ' have a textured upper travel surface 16.
  • One way of texturing upper travel surface 16 is to embed sand 18, gravel 20 or both in with wood fibre 14 in upper travel surface 16.
  • road mat 10 is formed entirely of multiple layers of thin wood fibre 14.
  • the cross-oriented las ers preferably include axial las ers 22 which are oriented parallel to longitudinal axis 21 of road mat 10 and transverse layers 24 which are oriented transverse to longitudinal axis 21 . It will be appreciated that there are other las er orientations which could be utilized.
  • Axial layers 22 and transverse layers 24 are compressed and bonded together by resins 26.
  • Wood fibre 14 can take various forms, such as elongated strips or shorter wafers.
  • bod ⁇ ' 12 has a first engagement 28 at a first end 30 and a second engagement 32 at a second end 34.
  • First engagement 28 is capable of engaging with a second engagement 32 on a bod ⁇ ' of a like road mat.
  • the process of making road mat 10 is the same process used for making oriented strand board and other strand based products. As this process is well known, it will not be further described.
  • strand based products do not come in thicknesses that approach three to seven inches.
  • Current strand based product fabrication uses heat to cure the resin. This involves the use of heat plates, often using steam injection. The thickness of strand based products is limited by the ability to apply heat to cure the resin. At best, heat plate technology is only effective within a range of two inches. There are two alternative approaches that are currently being considered to achieve the greater thicknesses.
  • One approach is to continue the deposit of wood fibre 14 until the required thickness is attained, but use alternative means for curing the resin, such as microwaves or a radio frequency technology.
  • another approach is to form the thickest strand based products possible, bodies 12a, 12b, 12c and 12d, with existing heat plate technology and then use resin 26 to bond multiple oriented strand based products, bodies 12a, 12b, 12c and 12d, together to achieve the required thicloiess in a cold pressing process that will not adversely affect the integrity of the stand based products, bodies 12a, 12b, 12c and 12d.
  • a resin 26 be selected that is viewed as being "environmentally friendly”.
  • road mats 10 there are a number of advantages that road mats 10 provide:
  • Wooden mats are sometimes inconsistent in quality, depending upon the quality of the wood that is available at time of manufacture. It is increasingly difficult to obtain good quality wood at a reasonable price or at all. Road mats 10 will be of uniform quality.
  • the ⁇ ' can be tailored to meet the specific needs of the user regarding durability, strength, and other characteristics such as surface characteristics. Surface characteristics can be important to avoid slippage or surface damage. In order to avoid slippage the surface can be corrugated or sand can be embedded in the surface. In order to reduce surface damage by tracked vehicles, gravel can be embedded in the surface.
  • Road mats 10 are made entirely of wood fibres and resins with no metals, plastics or other materials, the ⁇ ' can be left in place to decompose naturally at the end of their use, thereby eliminating the environmental disturbance associated with removal.
  • the resins can be made to suit the durability requirements of the particular application.
  • the road mat can be engineered to disintegrate and start to decompose according to a schedule timed to coincide with the end of its projected use.
  • the mats would be too fragile to move and would, therefore, be useful for only a single use. It was discovered that the mats are very robust and can be used multiple times. In addition, the mats ma ' be pressure washed to eliminate contamination between work stations. Contamination is also less of an issue as there are no cavities in which mud and weed seeds ma ' become lodged. The mats ma ⁇ - be moved using a fork lift and only minimal damage in the form of chipping to the edges was seen when handling the mats with a forklift.

Abstract

L'invention porte sur un tapis de route possédant un corps entièrement constitué de couches multiples de fines fibres de bois comprimées et reliées les unes aux autres par des résines. Ce tapis de route est entièrement constitué de bois et est dépourvu d'éléments de fixation métalliques. Il peut être broyé et dispersé sur place ou laissé en place pour se décomposer naturellement à l'issue de son utilisation, permettant ainsi d'éliminer les perturbations environnementales associées à son retrait.
