我国道路施工工艺规范规定,大于20~30cm的石块不能用于填筑路基。在多石山区、少土山岭地区施工时要么把这些大石块剔除,要么破碎后填埋,这使得工期延长,成本增加。为此,常林股份公司与长安大学合作开发生产了YZ18JT型填石路基压路机,其振动轮的宽频、宽幅非定向振动及水平振动
China’s road construction specifications, the stones larger than 20 ~ 30cm can not be used to fill the roadbed. In the rocky mountainous area, the construction of the Shaodu Tu Mountain area either excludes these large rocks or shatters and then buries the landfill, which prolongs the construction period and increases the cost. To this end, Chang-Lin Co., Ltd. and Chang’an University to develop and produce YZ18JT-type rock fill roadbed roller, the vibration of broadband, wide-range non-directional vibration and horizontal vibration
