An Experimental Study on Prediction of Aged Deterioration of Asphalt Mixtures in Facing

Abstract

It has passed in about thirty years since asphalt facing type-dam is built for the first time to our country. As for asphalt mixtures used for asphalt facing in the meantime, degradation is progressing in response to exposure, such as sunshine, rain, an ultraviolet and oxygen. This paper is research on prediction of Aged Deterioration of asphalt mixtures in facing. In this research, prediction was studied paying attention to the examination of a SHRP standard. Consequently, it is possible to DSR test and BBR test that prediction of aged deterioration of asphalt mixtures in facing.
