低温領域におけるアスファルトのぜい化点 Scattering of Brittle Point of Various Asphalts
This paper describes the test results of penetration test, softening point test and Moriyoshi Breaking Point test for new asphalts and asphalts recovered from various fields. Flow and cracking of flexible pavements depend upon the brittle point of asphalts, but research of those points have not been conducted.It is concluded that scattering of brittle point of asphalts for new and recovered asphalts was remarkably large and it seems that those points controlled various crackings of flexible pavements.
