我省处于我国东北之北部,年平均温度0.4～37℃,结冻期间较长,一般自10月下旬至4月中旬将及6今月。在此期间虽然路基、路面非常稳定,但有些地区经常由于降雪量少,气候较干燥,加之此期间又为一年中的运输旺季,交通量较大,同时不能进行洒水保养,所以路面上加铺之磨耗层及保护层,磨损消耗很大,不仅给公路方面带来了很大困难。同时也间接的提高了运输成本。为此,首先在我省齐富养路段,由全体取工根据“就地取村、因地制宜、经济适用”的原则,利用结冻期长的特点,自1955年开始在结冻期间试用土封面和雪封面的方法来代替保护层,以延长磨耗层的使用期限。经过两年来的摸索,证明这个养护方法,在特
Our province is located in the north of the northeast of our country, the annual average temperature of 0.4 ~ 37 ℃, freezing period longer, generally from late October to mid-April and 6 this month. Although the subgrade and pavement are very stable during this period, some areas are often affected by a small amount of snowfall and a drier climate. In addition, during this period, the traffic season is heavy and traffic is not maintained. As a result, the road surface is added Shop the wear layer and protective layer, wear and tear consumption is great, not only to the road has brought great difficulties. Also indirectly increase transport costs. To this end, the first in our province Qifu maintenance section, by all the workers under the “place to take the village, according to local conditions, affordable,” the principle of the characteristics of the use of frozen period, since 1955 during the freezing trial of soil cover And snow cover method instead of protective layer to extend the wear layer of life. After two years of exploration, prove that this conservation method, special
