近年来,我们担负了一些公路改建测设任务,混合交通中载重汽车比较多,尤其是厂矿专用线,后轴重大于6吨的汽车换算为解放牌CA-10B车往往超过换算总数的50％,根据柔性路面设计规范,要以黄河牌JN-150车为路面设计标准车。另一方面,选用与此相适应的标准车进行原有公路弯沉测量是正确地确定计算弯沉值的前题。这关系到改建设计是否经济合理,满足使用要求的预期效果。
In recent years, we have assumed some tasks of reconstructing and reconstructing highways. In mixed traffic, there are many trucks, especially for factories and mines. Automobiles with a rear axle weight of more than 6 tons are more than 50% of the total number of vehicles converted to Xiefangpai CA- According to the flexible pavement design specifications, it is necessary to design the standard car with the Yellow River JN-150 as the pavement. On the other hand, the selection of the standard car that is compatible with this method to make the original road deflection measurement is the prerequisite for correctly determining the deflection value. This is related to the rational design of the rebuilt design to meet the requirements of the expected results.
