“…Yol mühendisliğinde SK katkısının asfalt modifikasyonunda bir katkı malzemesi olarak kullanıldığı çalışmalar incelendiğinde, SK katkısının bağlayıcıların kıvamını arttırdığı ve reolojik özelliklerini iyileştirdiği görülmüştür [21][22][23]. SK katkısının sıcak karışımlarda kullanıldığı çalışmalar incelendiğinde, SK katkısıyla sıcak karışımların stabilitesinin arttığı ve suya karşı hassasiyetinin önemli oranda azaldığı ifade edilmiştir [22]. Başka bir çalışmada Yao ve arkadaşları, SK katkısının karışımın esneklik modülünü geliştirdiğini ifade etmişlerdir [24].…”

Bu çalışmada, atık lastiklerden elde edilmiş olan siyah karbon (SK) katkısının sıcak karışım asfalt kaplamaların nem performansı üzerindeki etkileri araştırılmıştır. Bu amaçla, penetrasyon sınıfı B 160/220 olan saf asfalta ağırlıkça %5, %10, %15 ve %20 oranlarında SK eklenerek modifiye asfaltlar hazırlanmıştır. Saf ve modifiye asfaltların fiziksel özellikleri penetrasyon, yumuşama noktası ve düktilite deneyleri ile, işlenebilirlik özellikleri ise dönel viskozimetre (RV) deneyi ile belirlenmiştir. Daha sonra, karışım tasarımı için agrega ve saf asfalt kullanılarak Marshall tasarım yöntemine göre karışımın optimum asfalt içeriği belirlenmiştir. Belirlenen bu oran esas alınarak saf ve modifiye asfaltlar ile sıcak karışım numuneleri hazırlanmıştır. Saf ve SK katkılı modifiye karışım numuneleri Marshall stabilitesi, kalıcı Marshall stabilitesi (RMS) ve dolaylı çekme mukavemeti (ITS) deneylerine tabi tutulmuştur. Fiziksel test sonuçlarına göre, SK katkısı ile modifiye bağlayıcıların sertliğinin ve işlenebilirlik sıcaklıklarının arttığı görülmüştür. Karışım test sonuçlarına göre, Marshall stabilitesi, RMS ve dolaylı çekme mukavemeti oranı (ITSR) değerlerinin özellikle %10SK oranında önemli artışlar göstermesi sebebiyle yol kaplamalarının nem performansı üzerinde SK katkısının iyileştirici bir etki gösterdiği görülmüştür.

“…At present, the main method to enhance asphalt properties is to modify asphalt. There are various kinds of additives, such as polymers [ 5 , 6 , 7 ], silica gel [ 8 ], carbon black [ 9 ], carbon nanotube [ 10 ], resin [ 11 ], polyphosphoric acid [ 12 ], wax [ 13 ], etc., to modify asphalt according to different needs. Due to the international conscience of society that a more sustainable development is needed, more efficient management of the waste products is being conducted [ 14 , 15 , 16 , 17 ].…”

As an additive to improve the performance of asphalt binder, tire pyrolysis carbon black is gradually being used in road engineering, but the effect of carbon black (CB) with different particle sizes on asphalt modification remains to be further studied. In this study, three kinds of particle sizes and three kinds of contents of CB were used to modify asphalt, and different tests were conducted to research the high temperature performance and fatigue resistance of carbon black modified asphalt binder. It is found that the addition of CB can enhance the rutting resistance and medium temperature fatigue performance of virgin asphalt binder in general. However, for CB of 270 μm and 2.6 μm, its addition under certain contents lead to the decrease of high temperature performance and fatigue performance of the asphalt binder. For aged asphalt, the addition of CB decreases the rutting resistance and improves the fatigue resistance. The recommended content and particle size of CB are 2% and 2.6 μm. This study refines the complex effects of CB on asphalt properties, providing a reference for determining the size and content of CB in asphalt modification.

“…Moreover, asphalt is more elastic, and its temperature sensitivity is reduced. Raquel et al [ 16 ] found that the mechanical properties of polymer-modified asphalt mixtures with and without carbon black are similar. However, according to the water sensitivity test, the cohesion of the mixture with carbon black is increased.…”

As environmentally friendly materials, carbon black and bio-oil can be used as modifiers to effectively enhance the poor high-temperature and low-temperature performance of base asphalt and its mixture. Different carbon black and bio-oil contents and shear time were selected as the test influencing factors in this work. Based on the Box–Behnken design (BBD), carbon black/bio-oil composite modified asphalt was prepared to perform the softening point, penetration, multiple stress creep and recovery (MSCR), and bending beam rheometer (BBR) tests. The response surface method (RSM) was used to analyze the test results. In addition, the base asphalt mixtures and the optimal performance carbon black/bio-oil composite modified asphalt mixtures were formed for rutting and low-temperature splitting tests. The results show that incorporating carbon black can enhance the asphalt’s high-temperature performance by the test results of irrecoverable creep compliance (Jnr) and strain recovery rate (R). By contrast, the stiffness modulus (S) and creep rate (M) test results show that bio-oil can enhance the asphalt’s low-temperature performance. The quadratic function models between the performance indicators of carbon black/bio-oil composite modified asphalt and the test influencing factors were established based on the RSM. The optimal performance modified asphalt mixture’s carbon black and bio-oil content was 15.05% and 9.631%, and the shear time was 62.667 min. It was revealed that the high-temperature stability and low-temperature crack resistance of the carbon black/bio-oil composite modified asphalt mixture were better than that of the base asphalt mixture because of its higher dynamic stability (DS) and toughness. Therefore, carbon black/bio-oil composite modified asphalt mixture can be used as a new type of choice for road construction materials, which is in line with green development.
