去年10月,我们承担了钱江二桥公路接线(主线)二期路面加铺工程的沥青路面铣刨工作,整个路段共铣刨沥青路面近8万m~2,要求铣刨后的基础平整度好,横坡为2％,高程允许误差范围为±1cm。根据我所现有的条件只能采用原西德Wirtgen公司的1300铣刨机进行铣刨,但该机器左侧找平电脑只能进行等厚度铣刨,不能进行横坡控制,这显然不能满足施工要求。对此,我们经过试验,找到了比较合适的方法。
In October last year, we undertook the asphalt pavement milling work for the pavement of the second phase of the Qianjiang No.2 Bridge Highway (main line). The entire section of the asphalt pavement was planed to be nearly 80,000 m 2 in total. The basic leveling required after milling Degree is good, 2% cross slope, elevation allowable error range of ± 1cm. According to my existing conditions, the original West Wirtgen 1300 milling machine can only be used for milling, but the leveling machine on the left side of the machine can only perform the same thickness milling and can not be controlled by the slope, which obviously can not meet the requirements of construction Claim. In this regard, we have tried to find a more appropriate method.
