摘　　要：为了有效提高沥青混合料面层的压实度和平整度,在有效碾压作用时间的基础上,通过建立数学模型,从理论上分析了平行四边形推进法压路机前进距离L1与倒退距离L2确定的方法。研究结果表明:采用平行四边形推进法,可有效提高沥青混合料面层的均匀度;前进距离L1和后退距离L2要根据压路机运行的速度、摊铺速度、始终点温度和外界环境温度等因素综合考虑;适当选择L1和L2就可实现四的倍数的多遍压实,便于自动控制;并且在摊铺机连续摊铺的过程中,压路机不得随意停顿。压路机不得在未碾压成型并冷却的路段上转向、调头或停车等。In order to improve the asphalt mixture surtace compacmss of the effective compaction time, a mathematical model based on the theory of parallelogram was used to determine the forward distance L1 and backward distance L2. The results show that the parallelogram push method can effectively improve the surface layer uniformity of asphalt aggre- gate mixture. The forward and backward distance L1 and L2 are affected by roller speed, paving speed, temperature and other factors. Proper L1 and L1 can achieve four multiple times compac- tion and convenient automatic control, and in the process of paving, roller should not be paused. Roller should not turn, turn around or park on sections not rolled and cooled down. 2 tabs, 4 figs, 7 refs.
