由于对道路沥青的生产包装、储运、加热等环节尚无统一标准,造成装、运,储、使用等过程中的低效率、能源浪费、环境污染、沥青浪费等现状,正如前文所述,是我国黑色路面施工及养护中存在的实际情况。近几年来随着桶装沥青(多为进口沥青)的应市,沥青脱桶设备也应运而生,这比起采取罐装、池贮的方法给管理和施工部门带来了很多方便,如运输无需专用车辆,储存也简便等。但如推行桶装沥青,仍存在包装投资大,运输装卸需要起重设备,使用需要脱桶设备等问题。我认为道路沥青应大力推广采用袋装。道路沥青包装袋由内袋和外袋组成,内袋是采用聚烯烃共混技术合成的材料制成,耐热能力120℃,并在160℃以下能与沥青混熔,不影响沥青使用性能;外袋具有足够的强度及耐热、耐油和抗老化性能,保证在灌装、搬运及储存过程中不破裂,不
As there is no uniform standard for production, packaging, storage, transportation and heating of road asphalt, which results in inefficiencies in installation, transportation, storage and use, energy waste, environmental pollution and asphalt waste. As mentioned above, China’s black pavement construction and maintenance of the actual situation. In recent years, with the bunk of bitumen (mostly imported bitumen), bitumen stripper equipment has emerged, which brings many advantages to the management and construction department compared with canning and storage methods Transport without special vehicles, storage is also simple and so on. However, such as the implementation of bottled asphalt, there are still large packaging investment, transportation and handling needs lifting equipment, the need to use the barrel and other issues. I think road asphalt should be vigorously promoted using bags. Road bitumen bags are composed of inner bag and outer bag. The inner bag is made of polyolefin blend technology and has heat resistance of 120 ° C and can be mixed with asphalt at 160 ° C without affecting the serviceability of asphalt. Outer bag with sufficient strength and heat, oil and anti-aging properties, to ensure that in the filling, handling and storage process does not break, not
