“十一五”期间,我国公路建设取得巨大成绩,路网规模进一步扩大,以高速公路为主骨架的国家干线公路网初步形成,农村公路建设实现了历史性突破,通行能力和通达水平大幅提高。然而,由于多种原因,作为发挥和完善高速公路网辐射功能、承担区域交通运输主要通道、连接农村公路、具有承上启下重要作用的普通干线公路网的发展却明显滞后。《“十二五”公路养护管理发展纲要》(简称《纲要》)提出,到2015年,国省干线公路(高速公路除外)平均路面使用指数PQI大于80,且PQI小于70的路段比重下降至12%(次差级路)。《纲要》还提出“十二五”期间,每年普通国省干线公路实施大中修工程(含预防性养护)的里程比重不小于17%。
During the “Eleventh Five-Year Plan” period, great achievements were made in highway construction in our country and the scale of road network was further expanded. A national trunk highway network with the expressway as its main skeleton was initially formed. The rural highway construction achieved a historic breakthrough with its capacity and accessibility A substantial increase. However, due to various reasons, the development of the ordinary trunk highway network, which plays an important role in connecting the rural roads with the main channel of regional transportation, has obviously lagged behind as the development and improvement of the radiation function of the expressway network. The 12th Five-year Plan for the Development of Highway Maintenance Management (the “Outline”) proposes that by 2015, the average pavement utilization index (PQI) of the trunk highways of other provinces and autonomous regions (excluding expressways) should be greater than 80 and the proportion of road sections with PQI less than 70 Drop to 12% (second-worst path). The “Outline” also proposed that during the “12th Five-Year Plan” period, the proportion of mileage carried out by large and medium-sized repair projects (including preventive maintenance) in ordinary national trunk provinces and cities every year should not be less than 17%.
