广西地处祖国南方,多雨湿热。全区年平均气温达17—22℃,年降雨量一般在1500～2000毫米之间。常用筑路材料的分布也极不平衡,如梧州、钦州、百色地区公路沿线的列级石料很少,石灰单价也很高(出厂价高达60元/吨以上),给我区油路施工带来一定的困难。但是,公路沿线的天然碎、砾石土料场和河砂砾料场还是有的。 为适应我区气候特点和料源分布情况,贯彻因地制宜、就地取材的原则,以降低油路造价,近几年来,在发展油路的过程中,除采用一般常用基层结构外,我们先后较多地采用了天然碎、砾石土掺灰(级配碎、砾石掺灰)、级配砂砾和水压碎石等基层结构。
Guangxi is located south of the motherland, hot and humid. The average annual temperature of 17-22 ℃, the annual rainfall is generally between 1500 ~ 2000 mm. Common road materials distribution is also very uneven, such as Wuzhou, Qinzhou, Baise highway along the column-level stone rarely, the unit price of lime is also very high (ex-factory price of up to 60 yuan / ton), to our zone oil pipeline construction zone To some difficulty. However, the natural crushed gravel along the highway, gravel soil material and river gravel yard still exist. In order to meet the climatic characteristics of our region and the distribution of material sources, we implemented the principle of using local conditions in line with local conditions in order to reduce the cost of oil production. In recent years, in the process of developing oil production routes, in addition to the commonly used grassroots structures, Multi-use of natural broken, gravel soil mixed with gravel (grading broken gravel mixed with gravel) graded gravel and hydraulic grassroots and other infrastructure.
