“…2 Recently, the use of synthetic zeolites as warm mix asphalt additives has been published. [1][2][3][4][5][6][7][8][9][10][11] Due to the size and uniformity of their pores, 7,12,13 4A zeolites are water carriers that are able to release water between 12 and 18% in weight when mixed with the asphalt, 14 preferably at a temperature greater than 100 °C. 1,4 A foaming effect is produced, this facilitates the asphalt workability and increases the aggregate coating at a warm mix asphalt temperature.…”

4A Zeolite was synthesized using rice husk ash (RHA) as a raw material in a microwaveassisted hydrothermal synthesis. Two new procedures were proposed: procedure A, using RHA as the raw material, and procedure B, using the depolymerized RHA. Both procedures were performed using microwave-assisted hydrothermal synthesis, and neither synthesis required an aging time. Crystallinities of over 90 and 80% were reached at 100 °C after 30 min of microwave heating for procedures A and B, respectively. The obtained zeolites were used as warm mix asphalt additives, and the performance of the zeolite obtained from procedure A was better. Additionally, the zeolite obtained from procedure A and commercial silane were used separately as asphaltaggregate adhesion promoter. An increase in the adhesion percentage from 30% of a blank sample to 94% was observed.

Karayolu ulaşımı, artan nüfus ve gelişen teknoloji ile birlikte günden düne daha yoğun kullanılan bir ihtiyaç haline gelmektedir. Bu nedenle, Bitümlü Sıcak Karışıma (BSK) kıyasla daha düşük sıcaklıklarda üretildiği için insan sağlığına daha az zararlı, düşük enerji tüketimi ile çevre dostu Ilık Karışım Asfalt (IKA) teknolojisinin gelişmesi gerekliliği doğmuştur. Ayrıca, artan trafik yüklerine bağlı olarak Marshall yöntemi ile üretilen asfalt kaplamalardan istenilen performansın alınamaması ile birlikte yaşanan sürüş emniyeti ve yolculuk konforundaki azalma, farklı tasarım yöntemlerinin de araştırılmasına sebep olmuştur. Bunların ışığında geliştirilen, uygulanacağı bölgenin iklim ve trafik koşullarını dikkate alan Superpave yönteminin ülkemizde yapılan araştırmaları ve uygulamaları oldukça yeni ve yetersizdir. Bu çalışmada, Marshall ve Superpave tasarım yöntemleri ile IKA üretmek için üç çeşit IKA katkısı (Sasobit, Rediset, Advera) ve bunlara alternatif olabileceği düşünülen doğal zeolit kullanılmıştır. Farklı tasarım yöntemlerine göre elde edilen numunelerin VMA (mineral agregalar arası boşluk oranı), VFA (bitüm ile dolu boşluk oranı) ve boşluk oranları tespit edilerek optimum bitüm oranları belirlenmiş ve sonuçlar birbirleri ile kıyaslanmıştır. Deneysel sonuçlara göre, IKA katkıları ile üretilen asfalt numunelerinin optimum bitüm miktarları geleneksel BSK'a oranla her iki tasarım yönteminde de daha düşük bulunmuştur. Ayrıca, doğal zeolit katkısı hariç diğer tüm IKA katkılar için optimum bitüm oranı Marshall tasarım yönteminde Superpave tasarım yöntemine kıyasla daha düşük çıkmıştır.

“…It is reported that the use of Advera® lead to reduced odour and blue smoke production with up to 60% reduction in volatile organic compounds, carbon dioxide, sulphur dioxide and nitrogen oxide emissions and energy savings up to 30% [8]. However, researchers mentioned that by adding Advera® into the binder will results in a more consistent mixture [9] but it is understood that the proper way of using Advera® is to add them directly into mixture during mixing phase in order to provide adequate expansion of bitumen [10]. Thus, the study of the rheological properties enables the proper understanding of the performance of bitumen with or without the additive.…”

Modification of asphalt to improve the overall performance of pavements has been the focus of numerous researchers in recent years. This paper discovered whether the use of chemical additives namely Advera® is possible to influence the physical and chemical bonding of asphalt binder grade 80/100 subjected to different aging conditions. The fundamental characteristics of modified binder containing 4%, 5%, 6% and 7% of Advera® were determined by conventional methods while chemical characterisation was assessed by conducting Fourier tTransform iInfrared sSpectroscopy (FTIR). With the aid of image tool, scanning electron microscopy (SEM) was employed to study the surface texture and morphology of Advera® modified binder.The results indicated that, the Advera® modified binder had improved the physical and chemical properties over base binder for both aging condition. The SEM images show that the microstructure of Advera® modified asphalt binder changed compared to the control asphalt binder. A good dispersion of Advera® particles in the asphalt binder matrix is observed. This is proved by the FTIR results which indicate that the stretching of hydroxide is increase when the Advera® is added in the virgin asphalt binder.
