Recently, in an asphalt mixture manufacturing plant, "environment" "safety" "energy saving and resource saving" is an important issue. Many plants already make efforts to save energy, that is, to reduce CO2 emissions by using low fuel consumption burners and devising to change the shape of the blades to improve the thermal efficiency in the drier. In addition, the heating and classification of stone materials and dust generated during mixing are handled by dust collectors. Furthermore, with regard to various materials used in plants, we are working on environmental conservation by emphasizing environmental pollution prevention and safety of working environment. However, recently, the location conditions of plants have diversified, such as the presence of residential areas in the vicinity of plants, and these measures are not enough. In this report, we report a part of the actual situation of "environment", "safety", "energy conservation and resource saving" adopted in plants in Japan. 1, Introduction to odor control In an asphalt mixture production plant, a special odor is generated by the trace amounts of hydrocarbon oxides and sulfur compounds when loading an exhaust stack or an asphalt mixture. In an asphalt mixture production plant, a special odor is generated by a very small amount of hydrocarbon oxides and sulfur compounds when the gas from the exhaust pipe and the transporting asphalt mixture. As a countermeasure against the odor of the exhaust pipe, a method of burning trace substances is adopted by using a deodorizing furnace, but since it consumes a large amount of energy, there is a problem of suppressing CO2 emission. In this report, we identify odor-causing substances from plant and propose odor reduction by deodorant suitable for these substances. 2,　Introduction to anti-adhesion agents for asphalt Conventionally, mineral oil such as heavy oil and diesel oil was applied to deal with the adhesion of asphalt mixture to the equipment of asphalt mixture production plant, dump for delivery, finisher at construction, road roller and so on. However, by using a large amount of these mineral oils, a part of the asphalt composite material is cut back, causing problems such as pot holes after construction. In addition, problems such as water pollution due to leakage of mineral oil are also raised. In this report, we propose a water - soluble and biodegradable anti - adhesion agent. 3, Introduction to Recycling Additives More than 70% of the asphalt mixture used in Japan is a recycled mixture. Effective utilization of recycled mixture is the most important question to be considered from the perspective of resource protection, energy conservation, cost reduction. In Japan, initially, blends with asphalt with high needle penetration and low softening point and amethod of adding crude by-products of lubricating oil production has been adopted. However, in the former, the ratio of the recycled asphalt mixture is limited to about 10 to 20%, and in the latter case, since it is high viscosity, it is necessary to heat at the time of use, that the recycling effect is not sufficient. In addition, there is a problem in that it contains a large amount of aromatic moieties, especially polycyclic aromatic moieties, which are likely to be carcinogenic. In order to solve these problems, in this report, the combination of several kinds of special mineral oils and the use of special additives are used to achieve low viscosity, high flash point, low aromaticity, And high recycle additives are proposed. Asphalt mixture manufacturing plants in Japan are located in urban areas near the demand of large cities, so the environment is well considered. Recently, regulations such as the Air Pollution Prevention Ordinance, the Anti-Odor Prevention Ordinance and the Noise Prevention Ordinance have been strengthened. Furthermore, the safety training for workers using SDS for hazardous substances has been complicated is in fact. In order to solve these problems, we are not limited to this report, but we fully understand the needs of the plant and develop products that meet the environmental, safety, energy and resource conservation key words. I would like to propose.
