我们尝到了科技的甜头科技不是省油的灯,但是我们尝到了科技的甜头,这是他开口的第一句话。他说,吉林省道长春到白城的一段路在采用了沥青马蹄脂碎石混合料技术(SMA)后,从 1997年竣工到现在除了保洁处理没有任何养护投人。2001年完成的200公里路用的也是这种技术,以后我们还要大规模地投入,今年要完成的522公里公路用的就是SMA结构。科技创新需要成本,因为运用新材料、新设备和新技术从短期来看,成本会增加。但是,从长远看不是增加了成本,而是降低了成本 ,别是降低了后期养护成本,困为科技成果的运用提高了质量。公路的质量怎么衡量?就是拿建成后的一段时间内的养护投入衡量,养护投入越少,公路建设质量就越好,养护投入越多,说明建设质量越差,所以建设中的偷工减料,势必给养护加重负担,反之,建设成本高一些,后期养护一身轻。一句话.在前期建设上投入多。在后期养护上必然投入少,省出钱来又可以用于建设,其实是省了钱。
We have tasted the sweetness of science and technology is not a fuel-efficient lamp, but we have tasted the sweetness of technology, which is his first words. He said that a section of road from Changchun, Jilin Province to Baicheng City, had not had any conservation inputs since its completion in 1997 and now after its use of asphalt mastic asphalt technology (SMA). The same is true of the 200-kilometer road completed in 2001, and we will have to invest a large amount of it later this year. The 522-kilometer highway to be completed this year is the SMA structure. Technological innovation costs because of the increased costs in the short term with the use of new materials, new equipment and new technologies. However, instead of increasing costs in the long run, the costs will be reduced instead of reducing the costs of maintenance in the future, which will result in the improvement of the quality of scientific and technological achievements. How to measure the quality of the highway? Is to take the time to build conservation input into the measurement, the less maintenance inputs, the better the quality of highway construction, conservation investment, the worse the quality of construction, so construction jerry-building, bound to give Increasing the burden on the conservation, on the contrary, the higher the cost of construction, the latter part of a light maintenance. In a word, invest more in the early construction. In the latter part of the conservation will inevitably invest less money out of the province can be used for construction, in fact, save money.
