重载交通超长寿命沥青路面技术研究概述

A Brief Account of Study on Super Long Service Life Asphalt Road Surface Technology Under Heavy Loading Trucks

介绍了国外长寿命沥青路面的材料力学性能研究状况、设计理念、设计方法以及成功范例，对国内沥青路面的现状与存在问题进行了分析，回顾了国内沥青路面研究的进展情况。针对我国道路运输中超限超载严重的现象，指出在我国实现国外意义上的“永久性”路面具有一定的困难。

This paper introduces the current research situation, design idea, design method and sueees sful examples of foreign long service life asphalt road surface material mechanical properties, and analyzes the situation and problem of our asphalt road surface. The research progress of our asphalt road surface is reviewed. In the light of the phenomenon of sever over loading in our road transportation, it is pointed out that there are difficulties to carry out ＂foreign-permanent＂ road surface in our country.
