近年来,随着我国经济的快速发展,公路运输交通量日益增长,车辆大型化、重载、超载等现象屡见不鲜,致使我国公路寿命使用越来越短,很多公路在使用两三年内就出现了大面积的车辙、开裂、路面下陷、泛油等破损现象。相比之下,国外的公路使用寿命则日渐延长,有些学者甚至提出了永久性和长寿命路面的设计理念,这种理念在现实实践中也取得了很大的实践成功。本文通过对国外成功案例的研究,对永久性沥青路面结构设计理念进行了初步探索,同时也从我国成功案例进行深入探讨,这对我国改进公路设计,延长公路使用寿命具有指导意义。
In recent years, along with the rapid economic development in our country, the traffic volume of road transport is increasing day by day. The phenomena of large-scale vehicles, overloading and overloading are commonplace. As a result, the road life of our country is getting shorter and shorter. Many roads appeared within two to three years Large areas of rutting, cracking, pavement sag, oil pan damage and so on. In contrast, the service life of the highway abroad is gradually prolonged. Some scholars even put forward the design concept of the permanent and long-life pavement. This idea has also achieved great practical success in practice. Based on the research of successful cases abroad, this paper explores the design concept of permanent asphalt pavement structure. At the same time, it also explores the successful cases in our country, which is instructive for improving the highway design and extending the service life of the highway in our country.
