我局1953、1954年曾在蔡鳄北路、黄兴中北路及五一路一连进行过两次柏油表面处理工作。1953年施工后的结果,表面普遍显行粗糙,1954年又进行一次单层封面,施工后不到半年,蔡锷北路及黄兴中北路开始开裂破损,冰冻以后更为严重,独五一路至今已两年多仍属完整。同样的做法,为什么有两种不同的结果呢?其原因主要是当时的技术理论缺乏,实际经验没有,在思想方法上存在着教条主义,缺乏实事求是的精神。当时对原路面铺砌层的厚度、路基土壤及地下水位等情况缺乏深入系统的分析研究1954年对此注意也不够,只单纯地要求路面表面光滑和保持路面不透水。因此,蔡锷北路(厚度不够、地下水位高、交通量大)和黄兴中北路
I Bureau in 1953, 1954 in Cai Crocodile North Road, North Road, Huangxing and Wuyi Road, twice consecutive surface treatment. After the construction in 1953, the surface was generally rough with a single cover in 1954. Less than half a year after construction, the cracking of Caizhe North Road and Zhongxing North Road in Huangxing started to crack and became more serious after freezing. It has been more than two years still intact. The same approach, why two different results? The main reason is the lack of technical theory at that time, the actual experience does not exist in the dogmatic ideological methods, the lack of the spirit of seeking truth from facts. At that time, the original pavement thickness of paving, subgrade soils and groundwater levels and other lack of systematic analysis of the situation in 1954 is not enough attention to this, only a simple requirement of the road surface smooth and keep the road impervious. Therefore, Choi Wan North Road (not enough thickness, high water table, traffic volume) and Huangxing Road in the North
