従来公知の方法によつて設ける。 Next, the construction of the cushioning pavement according to the present invention will be explained. As shown in FIG. 1, sand, soil, etc. of a predetermined thickness is spread on a base 1 and compacted with rollers. A predetermined amount of permeable asphalt emulsion, cutback asphalt, etc. is sprinkled onto the top surface of the layer, and the layer is permeated, and the upper part of the layer of sand, soil, etc. is bonded with bitumen, thereby imparting waterproofness and stabilization. Then, the cushion layer 2 is formed. When increasing the thickness of the cushion layer, it is preferable to process it in two layers. Also, the second
As shown in the figure, a predetermined amount of asphalt emulsion, cutback asphalt, etc. is mixed with sand, soil, etc., and a predetermined amount of asphalt emulsion, cutback asphalt, etc. is mixed and spread, and the sand,
The cushion layer 2 can also be formed by forming a bitumen-treated layer of soil or the like. When the cushion layer 2 is thick,
Construction will be done in two layers. To construct the buffer layer 5, for example, a mat made of long fibers 6 is laid on the cushion layer 2, and if necessary, a formwork is placed around the periphery to fill in the gaps between the fibers of the mat and form the buffer layer 5 to a predetermined thickness. A method of filling mortar with mortar and curing it, a method of filling mortar with a mixture of cut long fibers 6 to a predetermined thickness, a method of cutting long fibers 6 and filling with mortar by spraying, etc. . In either case, the combination of vibration can facilitate recharging. The filled surface of the mortar is smoothed with a rake, trowel, etc., and then hardened. After curing, the pavement is completed. Furthermore, when providing the protective layer 8, on the buffer layer 5,
It is provided by a conventionally known method.

シール厚さ５mmを施工して保護層を設けた。Example 1 The road surface is excavated to a depth of about 10 cm, and unevenness is leveled by sufficiently compacting it with vibrating rollers. 5.5 m 3 /100 m 2 of coarse sand with a moisture content of 3 to 5% by weight is spread and compacted with a vibroplate to create a 5 cm thick sand layer. Spray 300/ 100m2 of 53% by weight). Penetration is about 2 cm on average. Next, a continuous glass fiber strand mat (bulky, 5 cm thick) was laid on top of this cushion layer. Next, from this top surface, about 7.9 tons/100m of mortar is mixed with 1 part by weight of cement, 2.2 parts by weight of sand, 2.5 parts by weight of asphalt emulsion for mixing with cationic cement (60% by weight of evaporation residue), and a small amount of water. Pour 2 into it, create a vibration and charge it. In this way, the pine is contained within the filled mortar layer. Then, let the mortar harden. The finished surface is the same as the original road surface or is slightly raised. In this way, the pavement body of the present invention was constructed. Two days later, a 5 mm thick slurry seal made of cationic asphalt emulsion and coarse sand was applied to the surface to provide a protective layer.

路面より１cm程高くなつている。Example 2 The road surface is excavated to a depth of about 10 cm, and unevenness is leveled by sufficiently compacting it with vibrating rollers. Spread 5.5 m 3 /100 m 2 of coarse sand with a moisture content of 3 to 5% and compact the vibroplate. Next, Pennekote E is sprinkled on the top surface at a ratio of 300/100 m 2 to allow it to penetrate. Spread 3.3m 3 /100m 2 of coarse sand on top of this and compact it with a vibroplate. Next, Pennekote E is sprinkled on the top surface at a ratio of 200/100 m 2 to allow it to penetrate. Thus, a cushion layer with a thickness of 8 cm is formed. From the top, 1 part of cement,
A mortar made by mixing 2 parts of sand and 2.4 parts of asphalt emulsion with a small amount of water and glass fibers (cut into 3 cm lengths) are sprayed at the same time. The amount of fiber is 2.5% by volume of the mortar. The amount of mortar is approximately 5.5t/ 100m2 . Vibration was sometimes used, and the surface was pressed down with a trowel. Filling was thus completed and the mortar was cured to form a 3 cm thick buffer layer. This finished surface is approximately 1 cm higher than the conventional road surface.
