不同温度下再生骨料沥青混凝土动态抗压性能研究
Study on dynamic compressive properties of recycled aggregate asphalt concrete with different temperatures
摘要
Abstract
To further study the applicability of recycled aggregate asphalt concrete to hydraulic structures,this paper studies the dynamic mechanical properties of this concrete in different temperature environments.Its dynamic compressive performance is examined for the temperature range of-10℃to 10℃and the strain rate range of 10-5 to 10-2 s-1.The test results show that the compressive strength and elastic modulus are inversely proportional to temperature and proportional to loading rate;the peak strain is proportional to temperature and inversely proportional to loading rate.An analysis of temperature influence factors and correlation coefficients reveals that both compressive strength and elastic modulus gradually decrease with the rising temperature and tend to certain constant values.关键词
