摘要: 为了做到碾压机械配置合理有效, 分析了常用碾压机械的性能和沥青道面铺筑的特点, 提出了从沥青拌和厂的产量、摊铺机的生产效率和摊铺厚度、施工气候条件等因素综合选择并确定碾压机械的类型与型号。结合机场跑道沥青铺筑实践, 对碾压作业段长度、碾压速度与压实度的关系、压路机有效工作时间系数等影响碾压机械配置的因素进行了系统试验研究, 提出了计算压路机生产率的方法, 并给出了从压路机的轮宽、碾压遍数、有效作业段长度、摊铺机的速度及宽度等参数合理配置碾压机械的方法与计算公式。通过三个机场工程的实际应用, 计算结果表明碾压机械配置效果良好。Abstract: Taking into account of such factors as the output of asphalt mix machines, production efficiency and paving depth of pavers and weather conditions, this paper analyzed the perform-ances of common rolling compaction machines and features of asphalt pavement construction to determine the types and model of machines. After a systematic experiment on the factors affect-ing the rolling compaction machine configuration such as the rolling compaction operation section length, the relation between rolling speed and compaction degree, roller grader effective working time coefficient, the paper put forward the method to calculate rollers' production rate and the method and formula of rationally disposing rolling compaction machines. The applied result proves this methods are effective.
