Özet
In this study, the Marshall Stability(MS) of asphalt concrete under varying temperature and exposure times was modelled by using fuzzy logic and statistical method. This is an experimental study conducted using statistics and fuzzy logic methods. In order to investigate the Marshall Stability of asphalt concrete based on exposure time and environment temperature, exposure times of 1.5, 3.4.5 and 6 h and temperatures of 30,40 and 50 degrees C were selected. The MS of the asphalt concrete at 17 degrees C(in laboratory environment temperature) was used as reference. The results showed that the MS of the asphalt core samples decreased 40.16% at 30 degrees C after 1.5 h and 62.39% after 6 h. At 40 degrees C the decrease was 74.31% after 1.5 h, and 78.10% after 6 h. At 50 degrees C the stability of the asphalt decreased 83.22% after 1.5 h, 88.66% after 6 h. The relationships between experimental results, fuzzy logic model and statistical results exhibited good correlation. The correlation coefficient was R = 0.99 for fuzzy logic model and R(2) = 0.9 for statistical method. Based on the results Of the study, it could be said that both the fuzzy logic method and statistical methods could be used for modelling of the stability of asphalt concrete under varying temperature and exposure time.
