The design parameters used to design the thickness of the flexible pavements such as the amount of traffic, the strength of subgrade soil, the characteristic of meterials, and the factor of enviornment are not constant. Due to the different factors of consideration, therefore, various design methods were developed for the purpose of design pavement Meanwhile, around 10 different design methods were used in Taiwan highway system For the comparison purpose, five best design methods are chosen and reported in this research, and these five design metheds are (1) 、 GI Value Method (Al, 1956) (2) 、 CBR Value Design Method(3) 、 AASHTO Design Method(1972) (4) 、 R Value Design Method (5) 、 Mr Value Design Method (Al, 1981); In this paper, the discussions and compar isons were made between there five suggested methods. In addition, the decision and suggestion will he made from these five design methods for different application of design (Keywords:flexible pavement,GI value,CBR value,R value,Mr value) ＊營建工程才鄴衍系講師
