When vehicles driving in poor ground conditions and soft soil roads which are not easy to pass, they are prone to be tracked or silt trapped and unable to pass successively, which is especially the case in military action. Early in order to overcome the inconvenience of the muddy swaps, people usually use artificial or mechanical method to pave fast road. The fast road is made of rigid materials which were hinged together. The Main characteristicof the fast roadis their high bending stiffness, so that the fast road has very good bearing capacity. The main shortage of the fast road is that most of them are made of metal, and they are too heavy to install and transport, which is very inconvenient. The military activities often face poor terrain conditions, which promotes the development of the fast road.Early the military mainly use the fast roads of block structure, articulated beam structure and hinged plate structure. In order to make the fast road more light, and then a portable road is developed.Portable road is a kind of road pavements which are easy to transport and install, mainly laid on the soft dirt road surface, to enable the traffic to pass successfully.The main characteristic of the portable road is its light weight, easy to carry and easy to install.The earliest portable road is composite pavement.Later, in order to further reflect the "portable" function of the pavement materials, FranceDeschamps company developed a new kind of portable roads namedportable textile mating, which is weaved by high-strength polyester monofilaments, greatly reducing the weight of the pavement materials. The length direction (warp) of the matting is flexible and the zonal has higher bending rigidity, which leads to a high bearing capacity.In order to study the influence of the fabric structure on its bearing capacity, we analysis the structure of the portable textile mating developed by the FranceDeschamps company. Firstly, analyze the material, parameters, warp density and weft density of the sample fabric, and then weave on the automatic loom. Determine the best parameters of the fabric through many experiments. Secondly, establish the geometric structure model of the weft side of the fabric. Do the fabric’s weft side slice, and analyze the geometric structure of the weft side of the fabric. Make sure the fabric’s geometry parameters and establish the relationship between the parameters.Analyze the forming principle of the corrugated structure on the weft side of the fabric according to its geometric structure mode and weave structure. Finally, design two different kind of fabrics, a changed honeycomb fabric and a triple weft fabric, then do three point wending test on the fabrics and analyze the influence of the structure of the fabric on its bearing capacity.Results show that the fabric’s processing parameters are shown as following:the warp of the fabric is made of polyester whose diameter is0.5mm, the weft of the fabric is made of polyester whose diameter is1.2mm, the warp density of the fabric is180root per10cm, the weft density of the fabric between60root per10cm to60root per10cm, the edge of the made of4cotton yarn, plain weave. The fabric can be weaved on the automatic loom smoothly with a stable structure. Observe the fabric’s geometric structure of the its weft side from its slices. Make sure ten geometric structure parameters and six relations between the parameters. Analyze the fabric’s processing principle of its geometric structure on its weft side according to its weave structure.The analysis shows that regular increase (or decrease) of the floating of its weave structure make the fabric present a triangle structure of bottom edge paralleled to each other. Then do the three point bending test to the fabrics, and the result shows that the changed honeycomb fabric has a higher bearing capacity.
