Effect of Cocamide Diethanolamide chemical on adhesion between bituminous binder and aggregates

As a result of the decrease in adhesion formed between aggregates and bituminous binder, cracks, potholes and raveling occur in the pavement In order to increase the adhesion between aggregates and bituminous binder, the usability of Cocamide Diethanolamide which is chemical material was examined for the first time. Cocamide Diethanolamide is added to bituminous binder at a rate of 1%, 3%, 5%, 7% and 9% and homogeneously mixed using a high shear temperature-controlled mixer at 2000 rpm for 165 degrees C and 1 hour. In addition to the conventional bitumen experiments on the bituminous binders which are modified with different ratios of Cocamide Diethanolamide, adhesion and stripping tests were carried out. Vialit Nicholson and California adhesion and stripping tests were carried out to examine the effect of the material used in the study on adhesion formed between bituminous binder and aggregate. According to the results of the Vialit test, it has been observed that the adhesion between the bituminous binder and aggregates increased by 87.5% as the amount of the Cocamide Diethanolamide material added to bituminous binder increased. In the Nicholson and California stripping tests, it was observed that bituminous binder which modified with 5% Cocamide Diethanolamide has significantly effective on aggregates.
