从有关部门获悉,我国特种水泥产量仅占全国水泥总产量的1.4%,供需紧张。道路水泥特别紧缺。到去年末为止,我国有公路97.5万公里。但不够技术等级的占1/3,无路面的土路占1/5,在很大程度上影响运输质量、效益和成本。此外,全国还有500个乡没有通公路。为改变这一落后状况,国家“七五”计划要扩建、改建公路14万公里,还要新建干线公路、高速公路和其他公路。仅今年就将新建1.3万公里。据计算,修建一条9米宽的水泥混凝土路面的公路,每
It is learned from relevant departments that China’s special cement output accounts for only 1.4% of the country’s total cement output, with tight supply and demand. Road cement is particularly scarce. By the end of last year, China has 975,000 kilometers of highways. But not enough technical level accounted for 1/3, no pavement dirt road accounted for 1/5, to a large extent affect the quality of transport, benefits and costs. In addition, there are 500 townships across the country without access roads. In order to change this backward situation, the state plans to expand and rebuild 140,000 kilometers of highways in the “Seventh Five-Year Plan” and also build new trunk roads, highways and other highways. This year alone, 13,000 kilometers will be built. It is calculated to build a road 9 meters wide cement concrete pavement, each
