【摘要】：沥青混凝土摊铺机的作业参数一直是人们关注的焦点,然而目前对沥青混凝土摊铺机作业参数尚没有深入系统的研究,沥青混凝土摊铺机生产厂家和施工单位针对不同摊铺厚度及材料都无法给出合适的作业参数。针对这种现象,采用理论与试验相结合的研究方法,对沥青混凝土摊铺机面层施工作业参数进行了理论分析和试验研究,为沥青混凝土摊铺机作业参数的确定提供参考。首先,根据国家和行业标准的相关规定,以及对现场工地实际作业参数的统计分析,初步确定了作业参数的选取范围。然后,提出沥青混凝土摊铺机振捣夯锤重叠度和有效接触宽度的概念,依次从理论上确定了沥青混凝土摊铺机作业参数的取值。其次,分别以不同松铺厚度对沥青混凝土摊铺机作业速度,熨平板振捣梁振幅,重叠度,以及熨平板振动击实功等对沥青混凝土摊铺机作业参数的合理性进行了试验研究,对比不同作业参数下的作业质量,进一步确定了作业参数的选取范围。最后,以国内某高速路段为案例,按照试验得出的作业参数进行了面层摊铺作业,通过与施工方原有参数方案的试铺结果对比,验证了研究所的作业参数合理可行的。
[Abstract]:The operating parameters of asphalt concrete paver have always been the focus of attention. However, there is no deep and systematic study on the operating parameters of asphalt concrete paver. The manufacturer and construction unit of asphalt concrete paver can not give proper operation parameters according to different spreading thickness and material. In view of this phenomenon, using the research method of combining theory with experiment, the paper makes a theoretical analysis and experimental study on the operating parameters of asphalt concrete paver surface layer, which provides a reference for determining the operation parameters of asphalt concrete paver. Firstly, according to the relevant regulations of national and industry standards, and the statistical analysis of site actual operating parameters, the selection range of operational parameters is preliminarily determined. Then, the concepts of overlap degree and effective contact width of vibratory tamping hammer of asphalt concrete paver are put forward, and the operating parameters of asphalt concrete paver are determined theoretically. Secondly, the rationality of the operation parameters of asphalt concrete paver, such as the working speed of asphalt concrete paver, the amplitude of ironing plate vibrating beam, the overlap degree, and the work of ironing plate vibration compaction, are studied respectively with different loose spreading thickness. The selection range of operation parameters is further determined by comparing the operation quality with different job parameters. Finally, taking a high-speed road section in China as a case, the paving operation of surface layer is carried out according to the operation parameters obtained from the test. By comparing with the test results of the original parameter scheme of the construction side, it is proved that the operational parameters of the research institute are reasonable and feasible.
