摘　　要：Bituminous binders have been modified by using cocamide diethanolamide.The chemical material used in this study is used for the first-time on the purpose of modification of the bitumen.In addition to the conventional bitumen tests(penetration,softening point and ductility tests),adhesion and peeling tests(Vialit,Nicholson and California tests)were carried out on the bituminous binders which are modified with different ratios of cocamide diethanolamide.According to the results of the tests,the most appropriate additive ratio has been determined.Samples containing the reference bituminous binder and the bituminous binder modified with the most appropriate cocamide diethanolamide ratio were prepared using the superpave volumetric mix design method(SuperpaveTM).In accordance with standard method of test for resistance of compacted asphalt mixtures to moisture-induced damage(AASHTO T 283),the moisture susceptibility of prepared samples has been examined.In order to observe the changes in strength due to the temperature difference,prepared samples were subjected to the freeze-thawing test in accordance with standard test method for resistance of concrete to rapid freezing and thawing(ASTM C 666).
