路面设计的目标是通过合理的设计方法使得道路在设计使用年限内能够提供安全、舒适、快捷的服务。然而目前我国高速公路沥青路面普遍存在着初、早期破坏,且主要破坏形式同上个世纪90年代以前轻交通状况下相比已发生了一定的变化。过去,沥青路面损坏主要包括龟裂、车辙、低温开裂等,这也是路面设计时重点控制的损坏类型。但是,随着路面结构强度的提高和路面损坏期的提前,这些传统损坏出现得越来越少,有些已经不再出现,而目前出现的损坏,不论是其形态还是原因都十分不同。本文综合当前沥青路面设计与施工方面进行探讨。
The goal of pavement design is to provide the road with safe, comfortable and quick service through reasonable design methods. However, the asphalt pavement of our country nowadays generally has initial and early damage, and the main damage forms have undergone some changes compared with the light traffic conditions before the 1990s. In the past, asphalt pavement damage include cracks, rutting, cracking and other low temperature, which is also the focus of pavement control design of the type of damage. However, with the increase of the strength of pavement structure and the advancement of pavement damage, these traditional damage appear less and less, some of them no longer appear, and the current damage, whether its shape or reason, is very different. This article discusses the current asphalt pavement design and construction.
