四川省于去年10月间,在成都至新津段38公里的泥结碎石路面上,加铺了碎石磨耗层和保护层,迄今将近一年,全段都经受了雨季的考验,目前除双流至新津段的磨耗层略有飞石及少数的小坑槽外,成都至双流段仍然完整平坦。兹将铺装磨耗层的操作方法和施工中应该注意的若干问题介绍如下: 铺装磨耗层的操作方法: 1、操作程序:可分为(一)消扫路面(积泥、尘土、杂物必须除净,尤其是边缘的尘土);(二)洒水(润湿路面,特别是边缘);(三)挖路槽(将边缘扒松20～30公分,深为3公分成V形);(四)配料(把土、砂、石按比例分堆堆放);(五)拌和并初步扒平;(六)切实扒平(专人负责);(七)碾压,并经常洒
In October last year, Sichuan Province, over 38 km of Chengdu-Xinkijun clay-bonded gravel paved with rubble abrasion layer and protective layer, so far nearly a year, the whole section have been tested by the rainy season, the current addition to Shuangliu Xinjin section of the wear layer slightly fly stone and a small pit, Chengdu to Shuangliu still intact. The operation method of pavement wear layer and some problems should be noted in the construction are as follows: Pavement wear layer operation method: 1, operating procedures: can be divided into (a) elimination sweep the road (mud, dust, debris (2) watering (wetting the pavement, especially the edge); (3) digging the trenches (20-30 cm at the edge and 3 cm deep into a V-shape); (Four) ingredients (the soil, sand, stone stacked in proportion to the pile); (five) mixing and preliminary Pa Ping;
