佛山地区位于珠江三角州水网地带,耕地多为稻田,每年平均降雨量一般为1800毫米,最高达2400毫米,年降雨天数160天左右,热季长,地表温度高。原有公路大多数缺少承重层,路基低矮,经常受雨水和地下 水的影响,处于软弱状态,路面强度普遍不足。由于存在上述一些客观条件,更主要的是我们对油路基层的处理重视不够,对适应本地区条件的基层结构及材料缺乏认真深入的研究,造成一些油路早期破坏,教训是深
Foshan is located in the Pearl River Delta water network, mostly paddy fields, the average annual rainfall is generally 1800 mm, up to 2400 mm, annual rainfall of about 160 days, the hot season, the surface temperature is high. Most of the original road lack of bearing layer, low roadbed, often affected by rain and groundwater, in a weak state, the general lack of road strength. Due to the existence of some of the above objective conditions, what is more important is that we pay insufficient attention to the treatment of oil-bearing grassroots units. We have not conducted a thorough and thorough study of the grass-roots structure and materials that suit the conditions in our region, resulting in the early destruction of some oil passages.
