The chemical</span><span style="font-size: 9.000000pt; font-family: 'TimesNewRomanPSMT'">material used in this study is used for the first-time on the purpose of modification of the bitumen. In addition tothe 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 differentratios of cocamide diethanolamide. According to the results of the tests, the most appropriate additive ratiohas been determined. Samples containing the reference bituminous binder and the bituminous binder modifiedwith the most appropriate cocamide diethanolamide ratio were prepared using the superpave volumetric mixdesign method (SuperpaveTM). In accordance with standard method of test for resistance of compacted asphaltmixtures to moisture-induced damage (AASHTO T 283), the moisture susceptibility of prepared samples hasbeen examined. In order to observe the changes in strength due to the temperature difference, prepared sampleswere subjected to the freeze-thawing test in accordance with standard test method for resistance of concrete torapid freezing and thawing (ASTM C 666). </span></p></div></div></div>
