しての採算面で非常に不利な結果を餡く欠点がめった。The above-mentioned exogenous treatment of road construction excavated soil and asphalt grain contributes to the reduction of road civil engineering resources, the prevention of natural #1L fragmentation, and the prevention of public expenses associated with disposal of waste materials. In the conventional method, all of the soil is treated in a plant at one time to produce roadbed material and roadbed material for chicks and breeding, or it is treated on a vertical floor during the regeneration process.
Early on, when roadbed materials and roadbed materials became unusable or difficult to produce, a method was adopted in which the surface layer of the pilgrimage, such as lumps, was removed. The quality of the roadbed material itself deteriorates due to the mixing of a relatively large amount of Asquard lumps into the recycled roadbed material, and the surface layer inevitably becomes a source of contention. Recycling potted asphalt waste into roadbed material,
Moreover, disposing of the recycled surplus often has the disadvantage of having extremely disadvantageous results in terms of profitability for the entire plant.

目的とする。In view of these circumstances, the present invention improves the quality of roadbed materials and the added value of metal bodies by performing pre-treatment at a quantitative rate on the excavated soil before it is treated in a plant.
The purpose of this project is to compile a method for recycling excavation soil and asphalt waste materials for road construction that can improve the efficiency of recovery.

である。That is, before treating the excavated soil, the asphalt waste present in the excavated soil is roughly divided into 41
In terms of equipment and work, the center is divided by quantitative means, and asphalt waste material is divided into parts.
In addition to processing only the shallow side excavation and waste in a separate plant, the asphalt waste that has been dumped and, if necessary, the single-wheel asphalt waste that is brought in from the road surface. 19. The recycling treatment of double-thread piles will be carried out at the same time, and there will be no or almost no contamination of Asu 7 Alto Kaede as the material for Katsuojigong! i
