FIG. 1 is a cross-sectional view showing the structure of a road according to an embodiment of the present invention. A pavement material 1 according to the present invention is laid on a sufficiently compacted roadbed 2. The pavement material 1 is laid on the roadbed 2 using a rake so as to have a uniform thickness.

には、適量の水を添加するのが好ましい。[0012] The pavement material 1 is a vermiculite powder pulverized and fired at a high temperature, and lime, silica sand and sand.
More than one kind and a synthetic resin are used as main components, and these are kneaded and used. Vermiculite contains a large amount of water, and when heated, water is released and expands. The particles are accordion-like (bellows-like) and have a void layer. Become. Therefore, when kneading, it is preferable to add an appropriate amount of water.

It is preferable to mix 40% by weight and 5 to 20% by weight of the synthetic resin. Water is used to give respirability to the crushed and high-temperature calcined vermiculite powder and to determine the hardness when kneaded. Therefore, if it is less than 5% by weight, the kneaded state is too hard.
If it is more than weight%, it is too soft. Therefore, the range of 5 to 20% by weight is desirable for imparting respirability to the pulverized and high-temperature calcined vermiculite powder to obtain a preferable kneading state.

When the amount is too small, the effect as a stabilizer does not occur. Therefore, in order to take advantage of the characteristics of vermiculite powder that has been pulverized and fired at a high temperature, and to maintain the effect as a stabilizer, it is necessary to use 1
A range of 0 to 40% by weight is preferred. As the silica sand,

A range of 5 to 20% by weight is preferred. Examples of the synthetic resin include a urethane foam resin, for example, an acrylic polymer urethane resin.

Next, lime, silica sand No. 3, No. 4 and one or more of the four types of coarse sand are added in an amount of 20 to 30% by weight and kneaded with a mortar mixer or a mixing mixer for 1 minute, and then the urethane foam resin is added thereto. Add 11 to 13% by weight and knead for 2 to 3 minutes. Next, the fluid is discharged from the mixer outlet onto the roadbed on which the irregular rolling pressure has been completed, leveled, and roller rolling is performed. When the flattening and rolling are completed and completely cured, a top coat is applied to the surface to complete the construction. Examples of the top coat material include a mixture of urethane foam resin and ethyl acetate in a ratio of 4: 6 or 3: 7.
Apply 0.5 liter.
