る。2. Description of the Related Art Conventionally, in asphalt road pavement construction, asphalt heated and softened in a compound factory is transported to a site by a truck or the like, and cotton is used to keep asphalt on a truck bed. Alternatively, a canvas made of synthetic fiber is used as a cover. Asphalt transportation to construction sites requires long-term heat insulation due to traffic conditions and other road conditions, and the amount of transport per operation has been reduced due to stricter overloading regulations. With the conventional method, which was covered with canvas, the asphalt cooled quickly, especially in winter, and the asphalt hardened, causing a great loss at the construction site. Further, there is also a problem that asphalt adheres and becomes heavy when used repeatedly, resulting in poor workability.

In the composite cover of the present invention, a sheet in which at least one surface of a polyester base fabric is coated with a heat-resistant resin is used as a surface layer. The polyester base fabric is a woven or knitted fabric obtained by weaving or knitting a spun yarn obtained by spinning a polyester filament yarn or a polyester staple fiber. The heat-resistant resin covering the base cloth is a resin having a melting point or a decomposition point higher than that of the polyester of the base cloth and having releasability, and a silicon-based resin or a fluorine-based resin is preferably used. As a method of coating the polyester base cloth with the heat-resistant resin, a method such as coating or dipping can be adopted. When only one side of the base cloth is coated with the resin, the coating method is preferable.

しては，２０〜１５０ｇ／m2程度が好ましい。In the composite cover of the present invention, a non-woven fabric made of polyester fiber is used as an intermediate layer in order to enhance heat retention. The non-woven fabric may be a spunbonded long-fiber non-woven fabric that forms a non-woven sheet together with fiber formation, or a short-fiber non-woven fabric obtained by carding short fibers into a sheet and needle-punching. The basis weight of the nonwoven fabric is preferably about 20 to 150 g / m 2 .

た。EXAMPLE A 100-part polyester KR2038 manufactured by Shin-Etsu Chemical Co., Ltd. was used on a polyester base fabric having a warp density of 58 yarns / inch and a weft density of 53 yarns / inch, woven in a flat structure using a polyester spun yarn # 20 single yarn as the warp yarn. Two sheets are stacked with the coated side of the silicone resin composed of 50 parts of an inorganic filler coated at 70 g / m 2 on the outside, and the intermediate layer is made of 100% polyester fiber of 2d × 51 mm.
g / m 2 non-woven fabric, quilted and sewn.
The composite cover of the present invention having a size of 2.7 m x 3.8 m having the structure described above was obtained. As a result of using the obtained cover for a 2t dump truck for asphalt transport for 3 months, the temperature drop of asphalt and adhesion of asphalt were less than when two No. 5 cotton canvases were used.
