The study also looked at the relationship between destructive and non-dcstructive methods. In order to investigate the stability according to exposure time and environment temperature, exposure times of 1.5, 3, 4.5 and 6 h and temperatures of 30, 40 and 50°C were selected. The results showed that at the environment temperature of 17°C the stability of the asphalt core samples decreased by 40.16% at 30°C after 1.5 h and 62.39% after 6 h. At 40°C the decrease was 74.31% after 1.5 and 78.10% after 6 h. At 50°C the stability of the asphalt decreased by 83.22% after 1.5 h and 88.66% after 6 h. The results also pointed to a moderate negative relationship (R = -0.533) between second ultrasound and stability indicating that non-destructive ultrasound method can be used to predict stability. © 2007 Asian Network for Scientific Information.en10.3923/jas.2007.3870.3879info:eu-repo/semantics/openAccessAsphalt concrete; Asphalt core; Stability; Temperature; UltrasoundArticle72438703879N/A
