Description
技术领域technical field
本发明涉及道路工程设备技术领域，具体涉及一种沥青发泡装置及其工作方法。The invention relates to the technical field of road engineering equipment, in particular to an asphalt foaming device and a working method thereof.
背景技术Background technique
沥青路面使用一定年限后会产生各种类型及不同程度的病害，在交通与环境共同作用下路面材料逐渐老化，道路整体强度降低，损坏现象逐渐增多，路面病害的发展将严重影响道路的正常使用。传统道路维修常用方案有直接加铺和翻挖重建两种。然而这两种维修工艺均有较大的自身缺陷：在原路面上直接加铺新的结构层并没有将原路面的病害消除掉，只是暂时掩盖，并且将抬升路面标高，使路面结构更加复杂，给后续运营中的养护维修工作带来不便；翻挖重建的维修方式将在施工过程产生大量废料，废料的堆放储存也会占用大量的土地资源，造成资源浪费与环境危害。After a certain number of years of use, asphalt pavement will produce various types and degrees of disease. Under the combined action of traffic and the environment, the pavement material will gradually age, the overall strength of the road will decrease, and the damage will gradually increase. The development of road surface diseases will seriously affect the normal use of the road. . There are two common schemes for traditional road maintenance: direct overpaving and excavation and reconstruction. However, both of these two maintenance techniques have their own defects: directly adding a new structural layer on the original pavement does not eliminate the disease of the original pavement, but only temporarily covers it up, and will raise the elevation of the pavement, making the pavement structure more complex. It will bring inconvenience to the maintenance and repair work in the follow-up operation; the maintenance method of excavation and reconstruction will generate a lot of waste during the construction process, and the stacking and storage of the waste will also occupy a lot of land resources, causing waste of resources and environmental hazards.
常规的养护维修方法不仅致使大量翻挖、铣刨的沥青混合料被废弃，而且使得新石料和沥青资源过度开采，是一种极大的资源浪费，间接导致森林植被减少、水土流失，严重破坏生态环境。此外，减少碳排放已经成为全球共识，各行各业都在鼓励使用新技术新材料以达到节能减排的目标。在公路建设领域重点提到了以沥青路面材料再生利用为代表的交通建设材料循环利用技术应用。在以上背景下，我国需要大力发展绿色低碳的沥青路面养护维修新技术，而泡沫沥青冷再生技术就是这些绿色新技术的富有生命力的典型代表之一。泡沫沥青冷再生技术能充分利用旧有材料，降低能耗，大幅减少二氧化碳排放，提高路面使用性能，缩短施工周期。随着越来越多早期修建 的沥青路面进入大中修期，产生了大量废旧沥青混合料。泡沫沥青冷再生技术对泡沫沥青的发泡效果要求很高，沥青的发泡效果直接关乎泡沫沥青冷再生混合料的品质。Conventional maintenance and repair methods not only lead to the abandonment of a large number of excavated and milled asphalt mixtures, but also lead to over-exploitation of new stone and asphalt resources, which is a huge waste of resources, and indirectly leads to the reduction of forest vegetation, soil erosion, and serious damage. ecosystem. In addition, reducing carbon emissions has become a global consensus, and all walks of life are encouraging the use of new technologies and materials to achieve the goal of energy conservation and emission reduction. In the field of highway construction, the application of the recycling technology of transportation construction materials represented by the recycling of asphalt pavement materials is mentioned. Under the above background, my country needs to vigorously develop new technologies for green and low-carbon asphalt pavement maintenance and repair, and the foamed asphalt cold recycling technology is one of the typical representatives of these green new technologies. Foamed asphalt cold recycling technology can make full use of old materials, reduce energy consumption, greatly reduce carbon dioxide emissions, improve pavement performance, and shorten construction periods. As more and more asphalt pavements built in the early stage enter the period of major and medium repair, a large amount of waste asphalt mixture is produced. The foamed asphalt cold recycling technology has high requirements on the foaming effect of the foamed asphalt, and the foaming effect of the asphalt is directly related to the quality of the foamed asphalt cold recycling mixture.
已有的研究表明，泡沫沥青良好的发泡效果(较长的半衰期和较大的膨胀比)可进一步提高泡沫沥青混合料拌合均匀性，能提升泡沫沥青冷再生混合料的路用性能和耐久性。因此，改进泡沫沥青发泡装置是提高沥青的发泡效果的途径之一。Existing studies have shown that the good foaming effect of foamed asphalt (longer half-life and larger expansion ratio) can further improve the mixing uniformity of foamed asphalt mixture, and can improve the road performance and road performance of foamed asphalt cold recycled mixture. Durability. Therefore, improving the foamed asphalt foaming device is one of the ways to improve the foaming effect of asphalt.
