由于对水泥路面舒适性及养护问题的担忧,我国许多公路特别是高速公路多采用沥青摊铺路面,有些省甚至一刀切全部采用沥青摊铺。然而,我国沥青路面高速公路寿命普遍只有设计年限的一半左右,而且存在大量的早期损坏现象,由此看来,沥青路面并不像我们想象的那样,能完全取代水泥路面,并解决路面遇到的所有问题。随着水泥路面建设技术的提高,滑模摊铺机、缩缝传力杆、底基层垫层等设备和技术的应用,水泥路面已经能较好地解决“咯噔”跳车现象,养护技术也大大提高。与沥青路面相比,水泥路面已经具有与之相同的功效。因此,水泥路面在我国公路建设中应该有它的一席之地。为此,我们特制作本期专题,以期引起业界对水泥路面的关注,促进这种路面在我国公路特别是离速公路上的应用与推广。
Due to concerns about the comfort and maintenance of cement pavements, many roads in our country, especially the expressway, are mostly paved with asphalt, and some provinces even use asphalt paving on a one-size-fits-all approach. However, the life of asphalt pavement highway in China is generally only about half of the design life, and there is a large number of early damage phenomenon. From this, asphalt pavement is not completely replace cement road surface as we thought, and solve the road surface encountered All the questions. With the improvement of cement pavement construction technology, sliding mode paver, shrinkage dowel bar, basement cushion and other equipment and technology applications, the cement pavement has been able to better solve the “咯 噔” jump phenomenon, conservation Technology is also greatly improved. Compared with asphalt pavement, cement pavement already has the same effect. Therefore, the cement pavement in our country highway construction should have its place. To this end, we have specially produced this special issue with a view to arousing the industry’s attention to the cement pavement and promoting the application and promotion of such pavement on our country’s expressways, especially the expressways.
