Cocamide Diethanolamide Kimyasalýnýn Bitüm Modifikasyonunda Kullanýmý

Bu çalýþmada, Cocamide Diethanolamide kimyasalýnýn bitüm modifikasyonunda kullanýmý araþtýrýlmýþtýr. Katký malzemesi olarak Cocamide Diethanolamide kimyasalý seçilirken kimyasal ve bitüm arasýndaki sýcaklýða baðlý davranýþ, kimyasal yapý gibi özelliklerin benzer olmasý etkili olmuþtur. Buna ilaveten, Cocamide Diethanolamide kimyasalýnýn bitüm modifikasyonunda ilk kez kullanýlmýþ olmasý, bu çalýþmayý ayýrt edici kýlmaktadýr. Bitümün kimyasal ile %1, %3 ve %5 katký oranlarýnda, 155 °C ve 165 °C modifikasyon sýcaklýklarýnda, 30, 60, 90 dakika boyunca 1000 rpm karýþým hýzý kullanýlarak birden fazla kez modifikasyonu saðlanmýþtýr. Bu modifikasyonlar sonucunda her biri üç numune içeren 6 adet deney seti elde edilmiþtir. Farklý parametrelerin modifiye edilmiþ numuneler üzerine etkileri yumuþama noktasý, penetrasyon, düktilite, dönel viskozimetre deneyleri ile araþtýrýlmýþtýr ve Cocamide Diethanolamide kimyasalýnýn, bitümü yumuþattýðý ve bitümün iþleme sýcaklýðýný düþürdüðü görülmüþtür. Katký oraný arttýkça karýþtýrma ve sýkýþtýrma sýcaklýklarýnda görülen düþüþ, hem ekonomik hem de çevresel olarak fayda saðlamaktadýr.

Use of Cocamide Diethanolamide Chemical in Bitumen Modification

In this study, the usage of Cocamide Diethanolamide chemical for bitumen modification were investigated. When selecting Cocamide Diethanolamide chemical as the additive material, it has been effective that the properties such as behavior, chemical structure depending on the temperature between chemical and bitumen are similar. In addition, the usage of Cocamide Diethanolamide chemical for the first time in bitumen modification makes this study distinctive. Modification of bitumen with chemical was achieved more than once at the 1%, 3% and 5% additive ratios, 155 °C and 165 °C modification temperatures, using a mixing speed of 1000 rpm for 30, 60, 90 minutes. As a result of these modifications, 6 testing sets, each of them contains three sample, were obtained. The effects of different parameters on modified samples were investigated by softening point, penetration, ductility, rotational viscometer tests and it has been observed that Cocamide Diethanolamide chemical softens bitumen and lowers the processing temperature of bitumen. As the additive ratio increases, the decrease in mixing and compaction temperatures is beneficial both economically and environmentally.
