A mixed slurry of asphalt, asphalt, or a quick-hardening hydraulic substance is spread to fix the crushed stone aggregate, and then the slurry kneaded with the above-mentioned composition is spread on the surface of the crushed stone aggregate layer, and as needed. Accordingly, this is a simple paving method that uses vibrating rollers and the like to infiltrate and fill the voids.

短縮することができる。By fixing the particles on the surface of the paving aggregate, the surface will not be roughened by impact or rake when the slurry with the above composition is spread, and the finishing process can be simplified. Not only that, but it can also shorten the amount of time required.

7号砕石の単品か或いはこれらの混合物が使用可能であ
り、特に、7号砕石が好適である。In the above method, since the particle size of the aggregate used is large, the surface irregularities become large, and in order to achieve good flatness during finishing, it is necessary to increase the amount of grout slurry on the surface. However, this is a problem because the friction coefficient of the road surface decreases. Therefore, if crushed stone aggregate with a small particle size and a certain degree of porosity is sprinkled on the surface, the unevenness of the surface will be reduced, and at the same time, the coefficient of friction of the road surface will be increased. Mixtures of these can be used, with No. 7 crushed stone being particularly preferred.

There is no risk of moisture in the slurry moving to the roadbed and causing poor curing or filling due to lack of moisture.In this case, stone powder is mixed into the milk of the adhesive, Askuald, and hydraulic material, or moistened stone powder is used. By spreading the material after leveling it, you can save on the amount of material to be sprayed in advance.

In this case, calcium oxide and carunium aluminate compounds in cement undergo a hydration reaction to produce calcium aluminate hydrate, and further, a hydration reaction between this calcium aluminate hydrate and type anhydrite causes the formation of calcium aluminate hydrate. r, acicular crystal ettringite (

This method is based on a paving method that fixes crushed stone aggregate. Firstly, after preparing the roadbed, surface paving can be started immediately by simply leveling and compacting the crushed stone aggregate, which significantly shortens the construction period. Second, after the roadbed is prepared and before the crushed stone aggregate is spread, the above-mentioned material is spread on the roadbed, so that the boundary between the roadbed and the aggregate layer of the pavement is not affected. To provide a paving method that is less likely to cause insufficient curing or increased viscosity due to lack of moisture, resulting in insufficient filling. Thirdly, since the surface of the roadbed is covered with a fixed material, it is difficult to use crushed stone aggregate. After leveling, there is no digging into the material when filling the fixing slurry.
To provide a simple paving method that makes it easy to plan the purchase of materials.Fourthly, when spreading and filling the crushed stone aggregate layer with the fixed slurry, since the aggregate particles on the surface are fixed, To provide a paving method that does not roughen the surface of an aggregate layer during surface finishing and can simplify the surface finishing process after spreading.Fifth, after a certain period of time has passed after kneading, To provide a paving method that can be used for repairing arterial roads with heavy traffic, etc., because it develops strength and can be opened quickly in a short curing period.Sixth, it can also be used for surface pavement. , To provide a paving method that not only does not require large construction machines but also does not require special skills and can reduce construction costs. Seventhly, to provide a paving method that can reduce construction costs without requiring large construction machines or special skills. Seventh, To provide a paving method that does not require a special kneading plant, so there are no space or time constraints, and therefore, paving work can be easily carried out even in remote areas far away from the plant. By using crushed stone aggregate with a small particle size in the paving section, we obtained technical effects such as providing a paving method that can ensure a certain degree of surface smoothness without reducing the wear resistance of the surface.
