Abstract

The mesh structure/fabric laminate 3 is formed of a square or rectangular mesh structure 4 which has oriented strands connected at junctions which are thicker than the strands and have low orientated or unorientated nodules. On one side the surface of the nodules are melted and the fabric 2 is pressed into the nodules so that the plastics material of the nodules envelopes some of the fibres or filaments of the fabric 2 to form a mechanical bond without weakening the mesh structure significantly. The oriented strands are not substantially bonded to the fabric 2. <IMAGE>

Description

A MESH STRUCTURE/FABRIC LAMINATE Background of the Invention This application is a divisional application from GB 8925105. 2. The whole disclosure of GB 8925105. 2 is hereby incorporated in this application.
The invention relates to a mesh structure/fabric laminate which can be used for reinforcing a paved surface as described in GB 8925105. 2. The laminate can be used for reinforcing paved surfaces in general, but is particularly useful when reinforcing asphalt.
The mesh structure itself (which can be termed a grid when used to reinforce a paved surface) is preferably formed of plastics material; high-strength molecularly oriented polymer structures, for instance, a biaxially-oriented mesh in accordance with US 4 374 798, are used for reinforcing asphalt. However, other materials such as glass fibre grids, woven or knitted polyester meshes or metal grids may be used.
The Invention The present invention provides methods as set forth in Claims 1 or 6 and mesh structure/fabric laminates as set forth in Claims 5 or 7.
The strands can stand slightly proud of the fabric. The plastics material of the thicker parts envelopes some of the fibres or filaments of the fabric, and thus forms a mechanical bond between the mesh structure and the fabric. Provided this is carried out properly and provided the correct mesh structures are used, melting the surfaces of the thicker parts does not weaken the mesh structure significantly. However, other methods of laminating are possible, such as flame or hot melt adhesives bonding, but it is preferred to avoid any shrinking of oriented strands or adherence of the fabric to strands - thus the flame or the hot melt adhesives are preferably not applied excessively or at all to the strands.
The fabric can be of any suitable type, but when the laminate is used to reinforce a paved surface as described in GB 8925105. 2, it will have a fibrous or filamentary structure suitable for mechanical interlock with the cured or set adhesive used to adhere the fabric to the ground. The fabric should be sufficiently coherent to provide a good bond between the mesh structure and the ground, though the presence of the adhesive in the intesticies of the fabric can achieve this. The preferred fabrics are needled continuous filaments or staple fibres or spun bonded fabrics, but woven or knitted fabrics could be used.
The fabric will normally be formed of a plastics material such as polyester. Suitable geotextile fabrics are known.
The unit weight of the fabric could be from 80 gms/m2 2 to 250 gms/m2, but preferably about 130 gms/m The mesh structure can be made from any suitable material by any suitable method, but is preferably made from polypropylene or polyester, and is preferably made by the method described in US 4 374 798. The mesh pitch could be from 30 mm to 100 mm, but preferably is from 40 mm to 75 mm. The weight of the grid structure could be 2 2 from 150 gms/m2 to 400 gms/m2 but is preferably about 240 gms/m2.
The mesh structures are preferably such as to have pronounced nodules of unorientated or low-orientation plastics material in the junctions, and suitable mesh structures can be made in accordance with US 4 374 798.
Preferred Embodiments The invention will be further described, by way of example, with reference to the accompanying drawings, In which Figure 1 is vertical section through the paved surface of a road; and Figure 2 is schematic view showing the formation of a laminate in accordance with the invention.
Figure 1 Figure 1 shows a road base 1 which forms the ground to which has been adhered the fabric 2 of a mesh structure/fabric laminate 3 which includes the mesh structure 4. The fabric 2 is lowermost, and has been adhered to the road base 1 in any suitable manner, as discussed in GB 8925105. 2. Aggregate 5 has been placed on the laminate 3, and the pieces of the aggregate 5 pass into the meshes of the mesh structure 4 and interlock with the strands of the mesh structure 4. The aggregate 5 has been subjected to pressure in order to consolidate it, forming a flat road surface 6. Though the strands of the mesh structure 4 may be somewhat pressed down, it is found that some of them stand slightly proud of the fabric 2 and interlock with the pieces of the aggregate 5.
Figure 2 Figure 2 shows a known laminating machine having a heated roll 11 whose lower half is wrapped by a silicone rubber belt 12. A fabric 2 and a plastics material mesh structure 4 are fed between the roll 11 and belt 12 so that the roll 11 heats the high points or nodules (ie the thicker parts) of the mesh structure 4 through the fabric 2 and laminates them together to form the laminate 3.
By melting only the surface of nodules of the mesh structure 4 and pressing the fabric 2 onto the nodules, the molten plastics material penetrates the fabric 2 and produces a mechanical bond. Due to the arrangement, the heated roll 11 has little effect on the oriented strands of the mesh structure 4.
Example The machine of Figure 2 is used to make a laminate.
Mesh structure: The mesh structure is in accordance with Figure 21 of US 4 374 798. The mesh structure is a biaxially-oriented mesh structure having rectangular meshes, and formed by oriented strands connected together at junctions. Each junction has a thick unoriented or low-oriented nodule in its centre, surrounded by thinner, more oriented zones. The nodules are much thicker than the strands.
The mesh structure is made of polypropylene, which during manufacture is heat set and thus made resistant to reversion (shrinkage) at asphalt laying temperatures.
Grid mesh pitch 70 mm x 50 mm Grid unit weight 240 gms/m2 Grid thickness at nodules 4. 4 mm Grid width 4. 0 m Fabric: Raw material polyester Fabric constructions needled continuous filaments Fabric weight 130 gms/m2 Fabric width 4.0 m The laminate was used as described in GB 8925105. 2 to form a road surface using a conventional asphalt paviour to lay the asphalt.
The present invention has been described above purely by way of example, and modifications can be made within the spirit of the invention.

5. A mesh structure/fabric laminate comprising a fabric and a plastics material mesh structure which comprises oriented strands connected to each other at junctions containing parts which are thicker than the strands, the plastics material of said thicker parts enveloping some fibres or filaments of the fabric and thereby bonding said parts to the fabric, the strands of the mesh structure not being substantially bonded to the fabric.
