结合工程实际,阐述了高等级路面施工中,原材料质量控制的重要性,对粗细集料,沥青材料及纤维材料提出了明确的质量要求。介绍了SMA改性沥青玛蹄脂碎石混合料配合比组成设计,并对施工过程中的施工工艺及质量控制手段等重要环节进行了明确要求。通过对SMA改性沥青混合料路面结构的施工,不但先进的施工设备和高素质的施工人员是提高路面质量的保障,同时还必须对施工的各环节进行全方位管理控制。
Combined with engineering practice, the importance of quality control of raw materials in high-grade pavement construction is expounded, and clear quality requirements are put forward for the thick-grained aggregate, asphalt material and fiber material. The design of compounding ratio of SMA modified asphalt mastic composites was introduced, and the important links such as the construction technology and quality control measures during construction were clearly defined. Through the construction of pavement structure of SMA modified asphalt mixture, not only advanced construction equipment and high-quality construction workers are the guarantee to improve pavement quality, but also all-round management and control of all aspects of construction.
