道路が知られている。2. Description of the Related Art Conventionally, as an elevated road using a steel floor slab and an asphalt pavement material, a waterproof sheet 7 is laid on the upper surface of a steel floor slab 4 as shown in FIG. An elevated road with a structure in which goose asphalt 5 is placed is known.

熱が鋼製床版４に伝わって高温になり、そのため鋼製床
版４が熱により変形するという欠点がある。In the case of the conventional elevated road, when the goose asphalt 5 heated to 220 to 260 ° C. is placed on the waterproof sheet 7, the heat of the goose asphalt 5 is transmitted to the steel floor slab 4. As a result, the temperature of the steel floor slab 4 becomes high and the steel floor slab 4 is deformed by heat.

1 to 3 layers of a net-like woven fabric or net are adhesively polymerized with a bituminous emulsion layer on the prime coat layer on the surface of the floor plate, a bituminous emulsion mixture layer is further provided thereon, and a heated bitumen mixture layer is provided on the upper surface thereof. Things are disclosed.

さらに顕著になる。In the case of the above-mentioned conventional example, the adhesive polymerization layer of the bitumen emulsion layer and the mesh fabric or net or the bitumen emulsion mixture layer acts as a heat insulating layer. However, in this conventional example, because of the multilayer coating of the bituminous emulsion, There is a drawback that the coating work performed by temporarily blocking the traffic at the site is troublesome and takes a lot of time, and further it takes time to dry. Moreover, the above-mentioned drawbacks become more remarkable when a "thick layer" is used to improve the heat insulating effect.

た高架道路を提供することを目的とする。As described above, conventionally, the heat at the time of pouring the goose asphalt is effectively shielded so that the steel floor slab below it is not deformed by the heat, and at the site. There was no pavement for elevated roads that could be easily and quickly constructed. It is an object of the present invention to provide an elevated road which solves the above drawbacks.

粒子層６を固着するとよい。In order to advantageously solve the above problems, in an elevated road using the steel floor slab and asphalt pavement of the present invention, a heat insulating sheet 1 made of a nonwoven fabric of mineral fibers is used. A rubber asphalt layer 2 mixed with a mineral powder is integrally provided on the upper surface to form an adhesive heat insulating sheet 3, and the adhesive heat insulating sheet 3 is attached to the upper surface of a steel floor slab 4 installed on a support structure by an adhesive. After fixing, the goose asphalt 5 is cast on the rubber asphalt layer 2 containing the mineral powder in the adhesive heat insulating sheet 3. Further, the mineral powder particle layer 6 may be fixed to the surface of the mineral powder mixed rubber asphalt layer 2.

率よく行なわれる。According to the present invention, when the goose asphalt 5 is cast due to the presence of the adhesive heat insulating sheet 3, the transfer of the heat to the steel floor slab 4 is reliably cut off. Moreover, since the adhesive heat insulating sheet 3 is preliminarily manufactured as a single body, the work of forming the heat insulating layer is completed only by laying the adhesive heat insulating sheet 3 on the steel floor slab 4 at the construction site while unfolding the work. The goose asphalt 5 can be placed immediately and the construction work can be performed efficiently.
