Fatigue Characteristics of Pavement Concrete Considering Coarse Aggregate Types

굵은 골재 종류에 따른 포장 콘크리트의 피로특성

It is the purpose of this study to identify comprehensive fatigue characteristics of pavement concretes considering coarse aggregate types. The types of coarse aggregates considered are limestone, sandstone and granite, which are the most representative stones in Korea. The static strength tests were carried out to check the compressive strength, flexural strength at 7 and 28 days, and split tension strength at 56 day in order to minimize the various effect of strength during the test. The results are follows. The comprehensive fatigue models of pavement concretes were developed considering coarse aggregate types. The developed model showed a good relationship between aggregate types. The fatigue models with coarse aggregate types were shown, respectively. The combined fatigue models was also shown.
