沥青冷补料施工中可以着重关注以下几个方面的问题
尽管沥青冷补料比起热拌沥青,所受到了环境、天气影响小很多,沥青冷补料施工人员也需要注意,在各地区在应用沥青冷补料的过程当中应当依照实际施工环境以及道路养护实际需求,针对沥青冷补料的最佳配合比以及最优化施工工艺流程加以研究与分析。沥青冷补料施工中可以着重关注以下几个方面的问题:
Compared with hot mix asphalt, asphalt cold patching has little impact on the environment and weather. The construction personnel of asphalt cold patching also need to pay attention to it. In the process of applying asphalt cold patching in each region, we should study and analyze the optimal mix proportion and the optimal construction process according to the actual construction environment and the actual demand of road maintenance. In the construction of asphalt cold patching, the following problems can be focused on:
①应用沥青冷补料进行干线公路道路养护及路面修补的最基本前提在于干线公路路基的稳定性能够得到可靠保障。
① The basic premise of using asphalt cold patching material to maintain and repair the main road lies in the reliable guarantee of the stability of the main road subgrade.
②在冬季干线公路养护过程当中,道路路面坑槽的开挖应当去确保边缘垂直,并及时粉刷黏结油,确保冷补材料能够与路面裂缝处稳定结合。
② During the winter mainline road maintenance process, the excavation of road pavement pit shall ensure the edge is vertical, and timely paint the bonding oil to ensure the stable combination of cold patching materials and pavement cracks.
③若原料酸碱性测定为酸性,要想确保原料在施工过程中的黏结性与粘结稳定性,相关工作人员应当在沥青冷补料制备过程中掺配浓度为 1%~2%的抗剥落剂。
③ If the acid-base property of raw materials is determined to be acid, in order to ensure the cohesiveness and cohesiveness stability of raw materials in the construction process, relevant staff should mix anti stripping agent with concentration of 1% ~ 2% during the preparation of cold asphalt supplement.
