ようにしたものが一般的である。(Prior Art) Motorways, especially expressways, are provided with median strips to separate them from oncoming traffic. The median strip is divided into sections with curbs, the section area is covered with earthen mounds and ground cover plants such as grass, and a low-height section is placed in the center to block the headlights of oncoming vehicles. It is common to have trees of Chinese origin growing at intervals.

木の成育には好ましくないと云う問題点があった。(Problems to be Solved by the Invention) However, in the case of the above-mentioned median strip, the earth and sand from the median strip flows out onto the road during heavy rain, causing slipping accidents of vehicles, and weeds. They often spread and spoil the aesthetic appearance, requiring a great deal of effort to maintain and manage them. Therefore, in order to simplify maintenance and management, paving the separation zone with asphalt has been considered, but there is a problem in that it is not permeable to water and is not suitable for the growth of the above-mentioned trees.

FIG. 1 is a partially cutaway perspective view of a median strip according to the pavement structure of the present invention, and FIG. 2 is an enlarged vertical cross-sectional view taken along the line ■--■ in FIG. 1'. That is, the gist of the specific invention is that a base layer 2 of a motorway road separation zone divided by curbs 1, a water-permeable sheet 3 laid on the base layer 2, and a water-permeable sheet 2.

Japanese paper, linter paper, perforated vinyl sheet, or mesh cloth (provided that the mesh is finer than the reinforcing mesh 5 described later), etc. are used. The water-permeable sheet 3 prevents the reinforcing net 5 from sinking into the base layer 2 and ensures that the net 5 and the resin concrete layer 6 are completely integrated.

される。As mentioned above, the reinforcing net 5 is integrated with the resin concrete layer 6 to strengthen it, and various nets made of metal, glass fiber, synthetic resin, or carbon fiber are used. . In particular, expanded metal treated with anti-corrosion treatment is preferably used from the viewpoint of its shape characteristics and economical efficiency. That is, the expanded metal has a large apparent thickness at the top, and when viewed from the side, it has repeated saw-shaped irregularities, and has an excellent anchoring effect to the resin concrete layer 6, and is highly compatible with the resin concrete F6. This is because it can be more strongly integrated and manufactured at a lower cost. The mesh of the reinforcing net 5 needs to have an opening that can be filled with the granular aggregate 61 of the resin concrete layer 6, for example, 3 to 30 times the average particle diameter of the granular aggregate 61. The opening range is considered appropriate. Such a reinforcing net 5 is developed on the base layer 2 on which the water permeable sheet 3 is laid, and the portion corresponding to the tree planting area 4 is cut out. An angular shaped member 5I of aluminum or plastic is welded to this cut edge with one side standing up, and this upright side serves as a weir plate when applying resin concrete mortar.

合促進剤等の添加剤が加えられる。The granular aggregate 61 constituting the porous resin concrete layer 6 is composed of various types of gravel with a grain size of 1 to 15 cm, natural sand, No. 2 and 3 silica sand, or granulated slag ( Blast furnace slag) etc. are used. In particular, it is preferable to have a round shape and a relatively uniform particle size because it requires less binding resin and has a good appearance.For this reason, it is preferable to collect it from rapid rivers, near estuary mouths, or on the coast. Gravel and the like are suitable. In addition, examples of the synthetic resin binder for bonding the aggregates 61 to each other include hydrophobic synthetic resin binders such as urethane, epoxy, polyester, and acrylic (preferably methyl methacrylate), which are especially weather resistant.・Urethane and epoxy resins with excellent water resistance are desirable, especially liquid moisture-curing urethane, whose curing is accelerated by the action of moisture in the air, so when it is kneaded with the aggregate, it does not interact with the air in the voids. It hardens quickly on contact and is extremely convenient for handling. The mixing ratio between the aggregates 61 and the binding resin liquid should be determined to such an extent that the aggregates can be bonded to each other. One-component moisture-curing urethane is 2 to 1
5 parts by weight (solid content) is appropriate, which makes it 20-30%
A porosity of is obtained. That is, if the amount of urethane is less than 2 parts by weight, it will be difficult to achieve complete bonding between the aggregates, while if it exceeds 15 parts by weight, the voids between the aggregates will be filled with excess binder. Therefore, the resin liquid drips and closes the voids, reducing the porosity. As mentioned above, when aggregate and binding resin liquid are mixed together, resin concrete mortar is created.
Additives such as colorants, viscosity modifiers, various solvents, and bonding promoters are further added thereto as appropriate.

れる。The resin concrete mortar thus prepared is spread on the base layer 2 on which the reinforcing net 5 has been developed, and is applied to the upright side of the aluminum profile 51 welded to the cut edge in the tree-planting area 4. It is applied to a thickness (approximately 15 mm) that is between the upper end of the road surface and the road surface, and the point pressure is adjusted. When this resin concrete mortar hardens, as shown in FIG. 2, a large number of granular aggregates 61... are mutually bonded with the bonding resin 62 and integrated with the reinforcing net 5,
In addition, a water-permeable porous resin concrete layer 6 is formed which contains a large number of water-permeable holes 63 that communicate from the front to the back within the layer.

Further, rainwater falling on the pavement surface quickly permeates into the base layer 2 through the water-permeable holes 63 of the resin concrete M6 and the water-permeable sheet 3, contributing to the growth of the trees P. In addition, the resin concrete layer 6 is extremely strong because it is integrated with the reinforcing net 5. And tree planting Vj,

される。(Effects of the Invention) As mentioned above, in the pavement structure of the greening part of the motorway separation strip of the present invention, since the soil in the base layer is covered by the pavement, it does not flow out onto the road during heavy rain. Furthermore, there is no concern that weeds will spread, and maintenance is therefore extremely easy. Furthermore, since it has excellent water permeability, it does not hinder the growth of trees, and the function of the median strip is fully demonstrated.

リットが付加される。Moreover, since the water-permeable resin concrete layer is integrated with the reinforcing net, it is extremely strong and maintains its function as a pavement for a long time. If a removable water-permeable flat plate block is placed within the tree planting area as in the embodiment, it is extremely convenient when planting or replanting trees. Furthermore, the pavement construction method of the present invention simply involves laying a permeable sheet on the base layer of the separation zone divided by curbstones, spreading a reinforcing net on top of this, and then spreading resin concrete mortar. , is extremely low in Nm-, and has the added advantage that the cost for construction is low and the number of construction days can be shortened.
このように本発明の有用性類る大である。As described above, the usefulness of the present invention is enormous.
