近几年来,世界各国由于大量的沥青路面在重车作用下,发生大量的车辙、磨耗等严重损坏,使养护、维修的工作量和费用逐年增加。同时由于维修而阻滞交通已成为严重的社会问题。在这种情况下,具有普通水泥混凝土路面同样耐久性,在某些方面又弥补了普通水泥混凝土路面不足的碾压混凝土,近几年来有了较大的发展,而且是一种有很大发展潜力的新型路面结构,它具有施工进度快,养生时间短、水泥用量少、强度高、社会、经济效益显著等优点。下面就这种路面在国内外的发展现状、存在问题及今后发展方向,谈点我们的意见,供参考。
In recent years, due to a large number of asphalt pavements under the action of heavy trucks, a great deal of ruts, abrasions and other serious damage have occurred in many countries all over the world, so that the workload and costs of maintenance and repair have been increasing year by year. At the same time, blocking traffic as a result of maintenance has become a serious social problem. In this case, with the same durability of ordinary cement concrete pavement, and in some ways it has made up for the lack of ordinary cement concrete pavement RCC, has been greatly developed in recent years, but also a great development The potential of the new pavement structure, which has the construction progress fast, health time is short, with less cement, high strength, social, economic benefits and other significant advantages. Below this kind of pavement in the development of the status quo at home and abroad, problems and future development direction, talk about our opinions for reference.
