| Abstract: | Freezing-thawing test can be used to simulate changes of fatigue lifetime of pavement subject to water damage under the moist condition.This paper designs three gradations aiming at AC-25 asphalt concrete to carry out freezing-thawing fracturing fatigue test,to establish fatigue equations under conditions without water and with water,to analyze influences of different factors on fatigue property of asphalt mixtures after freezing and thawing,and to discover attenuation mechanism of fatigue property of aspha... |
