新疆气候干燥、缺乏水分、砾石路面表层的粒料松散,经汽车行驶后,出现横跨路面的波浪形状,其波幅不大,约0.7公尺,以其形如洗衣用的搓板,因此叫“搓板路面”。一般从现象上看、在粒料结合紧密的路面上不起或很少起“搓板”,坡顶和车站附近,车速减低便很少起“搓板”;路基土壤过湿,虽然路面结合紧密,也要起“搓板”。根据以上一些现象的推测,形成“搓板”的原因是: 1、粒料级配不良,气候干燥,含水量太少,不能
Xinjiang dry climate, the lack of water, gravel surface layer of loose particles, after driving by car, appeared across the surface of the wave shape, its amplitude is not large, about 0.7 meters, with its shape, such as laundry washboard, so called “ Washboard pavement. ” In general, from the point of view of phenomena, there is little or no “washboard” on the road surface with close combination of pellets, and there is very few “washboards” Also play “washboard.” According to some of the above speculation, the formation of “washboard” because: 1, pellet grading bad, dry climate, water content is too small, can not
