江苏省交通厅养路处于本年六月间在扬州市郊的扬圩、扬仙两段路上,采用天砾石、砖瓦屑、泥礓石、煤屑、湖沙、贝壳沙等六种材料,按不同成份、不同塑性指数和不同厚度,在不同交通量、不同路面的地段上,铺筑了各种类型的磨耗层。经过一个多月的观察鉴定,证明用煤屑等软质材料铺筑磨耗层,同样可获得良好的效果。兹将铺筑煤屑土壤磨耗层的情况及一些点滴的体会,简略介绍如下。
In June this year, the road maintenance department of Jiangsu Provincial Department of Transportation adopted six materials, namely gravel, brick tile, mud stone, coal dust, lake sand and shell sand, on the Yangwei and Yangxian sections of the outskirts of Yangzhou. Different components, different plasticity index and different thickness, in different traffic volume, different sections of the road, paved the various types of wear layer. After more than a month of observation and identification, proved that the use of soft materials such as coal mining paving wear layer, the same can be obtained good results. Here will pave the soil abrasion layer of the situation and some bits of bit of experience, a brief introduction is as follows.
