路に関するものである。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a weed-proof paved road that prevents the growth of weeds on farm roads, sidewalks, embankments, etc. where weeds tend to grow.

らず、クラック、ポットホールが生じ、舗装面の破壊を
招き、道路管理上も問題を有するのである。<Prior Art and its Problems> Although farm roads and sidewalks have relatively little traffic of vehicles and people, they are not completely free of traffic, so they are simply paved with asphalt concrete. Because such roads have low traffic volume and the surrounding natural environment is prone to weed growth, the roots of these weeds extend beneath the pavement surface early after the completion of pavement construction, and the roots of these weeds spread under the pavement surface on the shoulder of the road. Weed buds protrude and over time weeds grow thicker. It is natural that weeds grow on the roadside like this.
Not only do they impair the visibility of the road ahead and pose an obstacle to traffic safety, but they also cause problems in terms of road management, as cracks and potholes occur, leading to destruction of the pavement surface.
従来このような道路において雑草の発生を防止する工法

する工法等も存在したが、いずれも工費及び工期の点で
問題を有し、必ずしも実用的ではなかったのである。Conventional methods to prevent weeds from growing on such roads include spraying herbicides onto the sub-surface roadbed, but with this method, the chemical layer is extremely thin, and in the case of water-soluble agents, However, the weed control effect is low and does not last long because the herbicide is leached out by rainwater, etc., and the herbicide is decomposed by soil bacteria. Although there were methods of coating granular asphalt concrete with centent paste, all of them had problems in terms of construction cost and construction period, and were not necessarily practical.

るようにしたものである。Means for Solving the Problems> Therefore, in order to solve the above-mentioned problems, the weed-proof paved road according to the present invention has a surface layer made of asphalt concrete mixed with herbicides and/or repellents, By thickening the layer containing the drug and coating the drug with asphalt so that it sticks and prevents it from being leached by rainwater, etc., weed growth can be prevented over the long term or weeds can be killed. This is what I did.

要はない。Here, the chemical agent used for the weed-proof paved road according to the present invention will be explained. Any chemical can be used as long as it can be mixed with asphalt concrete, but in addition to heat resistance at the manufacturing temperature of the asphalt mixture, safety against toxicity, and corrosiveness of joint pressure, there are also In consideration of phytotoxicity to agricultural products caused by drug elution, it is preferable to use a substance that is insoluble in water. However, it is not necessary to use a substance that satisfies all of these conditions.

わめて大である。<Effects of the Invention> As described above, according to the weed-proof paved road according to the present invention, it is possible to form a thick layer containing herbicides and repellents, so that the drugs are effective against weeds, etc. In addition to being effective, the drug is coated with asphalt and fixed, preventing the drug from leaching out in rainwater, etc., so the effect of the drug can be maintained for a long time, and it also prevents the drug from eluting into rainwater or groundwater. Gradually,
In particular, it is less likely to cause chemical damage to crops, so it can be applied even on farm roads. In addition, repellents and herbicides do not have a negative impact on the asphalt concrete itself, and paved roads are less likely to be damaged by weeds, so they can dramatically extend the life of paved roads. The effect is extremely large.
