Abstract: 本研究は種々のアスファルトを用い,流動からぜい性に転移する種々のぜい化点を求めるため,アスファルトではフラースぜい化点試験,森吉ぜい化点試験,アスファルト混合物では熱応力試験,曲げ試験を行い,それぞれから得られる種々のぜい化点の相互の関係について述べている。実験の結果,本研究は種々のアスファルトおよびそのアスファルトを用いたアスファルト混合物の各種試験から求められた4種のぜい化点は互いに密接な関係にあることを明らかにした。また,アスファルト舗装の対象地域の外気温や舗装表面温度とわだち掘れや亀裂をも考慮した合理的なアスファルトの選定法についても提案した。
Failure phenomena such as crack and rutting are often seen in asphaltic pavements. It is considered that they depend upon the brittle points of asphalt and asphaltic mixtures, which are controlled by ambient temperature, by speed of vehicle, and by property of asphalt. Thus, it is very important that appropriate asphalt be selected to meet the circumstances and traffic conditions involved. Therefore, it is desirable to find a simple relation between the brittle points of asphalt and asphaltic mixtures and to elucidate the relationship between them and the brittle point of asphaltic pavements. This paper deals with the brittle points and their application to asphalts and asphaltic mixtures which transform from flow zones to brittle zones. We conducted a variety of tests in order to obtain various points of asphalts and asphaltic mixtures at low temperatures. In this study, it is concluded that the brittle points obtained with various tests are closely related to each other, and it is possible to select asphalts appropriate for different environmental conditions.
