Base layer and roadbed material compaction method and single-drum vibratory roller
The invention discloses a base layer and roadbed material compaction method and a single-drum vibratory roller. The method comprises the following steps of rolling for 1-2 times by using one or a combination of two of a double-drum vibratory roller, a single-drum vibratory roller and a pneumatic tire roller, using a high-speed high-frequency large-exciting-force single-drum vibratory roller for carrying out vibratory rolling for 1-3 times, and in the rolling process, enabling the rolling speed not to be smaller than 6 km/h, the vibration frequency not to be smaller than 31 Hz, the nominal amplitude not to be smaller than 1.8 mm, and the exciting force not to be smaller than 450 kN, rolling for 1-2 times by using a single-drum vibratory roller or rolling for 2-3 times by using a pneumatic tire roller, and rolling for 1-2 times by using a double-drum vibratory roller. The working mass of the high-speed high-frequency large-exciting-force single-drum vibratory roller is not less than 20 tons, the front wheel distribution mass is not less than 13 tons, the front wheel static line load is not less than 590 N/cm, the diameter of a vibrating wheel is not less than 1500 mm, and the rated power value of an engine for a power system is not less than 8 times of the working mass of the engine.
本发明公开了一种基层、路基材料压实方法和单钢轮振动压路机，包括如下步骤：用双钢轮振动压路机、单钢轮振动压路机、轮胎压路机中的一种或两种组合，碾压1～2遍；用高速高频大激振力单钢轮振动压路机进行振动碾压，碾压1～3遍，碾压过程中的碾压速度不小于6km/h、振动频率不小于31Hz、名义振幅不小于1.8mm、激振力不小于450kN；用单钢轮振动压路机碾压1～2遍或用轮胎压路机碾压2～3遍；用双钢轮振动压路机碾压1～2遍。前述的高速高频大激振力单钢轮振动压路机工作质量不小于20吨，前轮分配质量不小于13吨、前轮静线载荷不小于590N/cm，振动轮直径不小于1500mm，动力系统用发动机额定功率数值不小于其工作质量的8倍。
