沥青混凝土断裂韧性的光弹性贴片法研究

A Study of Fracture Toughness of Asphaltic Concrete by Photoelasic----Coating Method

本文介绍用光弹性贴片法来研究常用的路面材料──沥青混凝土的断裂韧性及开裂机理，并对三点弯曲梁进行了实验，结果表明光弹性贴片法可以在道路工程中应用。

This paper presents the study of fracture toughness and cracking mechanismof asphaltic concrete which is a conventional pavement material.The results of three-pointberding test of beam show that the photoelastic-coating method can be used in road construc-tion.
