Abstract
The temperatures of pavement of servicing road reach 60 degrees Celsius in summertime. The stiffness of asphalt mixture is often measured by resilient modulus test or uniaxial compression test at normal temperature. But, measurement method at high temperature is not defined. And shape of specimen also influences measured values in such condition. In this research, the measurement of asphalt mixture at high temperature using uniaxial compression test is investigated. As a result, the measurement method and the shape of specimen are proposed and the stiffness characteristics of dense grade asphalt concrete, porous asphalt concrete, stone matrix asphalt concrete and mastic asphalt concrete are measured.
