“…The density of calcium carbonate is 2.93 g/cm 3 and the melting point is 1339 • C. Some previous studies have indicated the calcium carbonate can also be used as a modifier [17]. Hao found that nanocalcium carbonate could be used as a modifier to improve both the high temperature performance and water stability of asphalt concrete [18].…”

With the rapid development of China’s e-commerce and logistics industry, a large number of waste express bags (WEBs) have been produced, which are difficult to recycle. The existing methods of waste express bag disposal often cause severe environmental pollution. It was discovered in this paper that the use of WEBs to modify bitumen could be an environmentally friendly way to recycle WEBs. This study aimed to investigate the feasibility of using WEBs to modify bitumen and promote the performance of WEB-modified bitumen. In order to verify this assumption, a series of basic or rheological experiments were conducted on different dosages of WEB-modified bitumen. The test results and phenomenon showed that the WEBs could be used to modify the binder homogeneously by using a high-speed shearing machine. The basic experiments showed that the WEBs could decrease the penetration and ductility while increasing the softening point and the rotational viscosity. Additionally, the rheological experimental data indicated that the high temperature performance was improved while the low temperature performance stayed the same. The Fourier-transform infrared spectroscopy (FTIR) results demonstrated that modification of the WEB was a physical modification without chemical reaction and the main component of the modifier was polyethylene. The fluorescence microscope (FM) data revealed the micro-structures of different dosages of WEB-modified bitumen. In conclusion, WEB can be a feasible binder modifier.

“…Furthermore, the addition of nano-clay can decrease the moisture damage of asphalt mixture [13,18]. A research conducted over nano-CaCO 3 concluded that the dynamic and residual stability of asphalt mixture increased at 6 % nano-CaCO 3 , which infers that both the high-temperature performance and water stability of asphalt mixture gets improved [19].…”

In the recent times, asphalt binder modification has emerged an inevitable alternative in the paving industry to ensure better performing pavements against the distresses caused by common factors such as; moisture susceptibility and high-temperature sensitivity of asphalt binders. Nanomaterials, as asphalt-modifiers, have proved to be the most promising materials in the industry owing to their higher active surface area and small particle size. This study was devoted to assessing the modification influence of three different types of nanomaterials, including nano-Bentonite, nano-CaCO3, and ZycoTherm, on the properties of asphalt binder and HMA. Conventional and rheological tests on asphalt binders, as well as, Marshall mix design and modified Lottman test on laboratory-prepared HMA specimens were conducted in order to signify the influence of nanomodification. The research findings suggested that nanomaterials can potentially enhance the high-temperature susceptibility resistance, storage stability, and rheological properties of asphalt binder samples. Mix design results revealed that the optimum binder contents decreased and Marshall stabilities were slightly improved with nanomodification. Moreover, the modified Lottman test results indicated that 0.1 % of ZycoTherm increased the TSR by 22 % as compared to the control mixture that infers its efficiency in terms of improving the HMA resistance against the moisture-induced damages.

Bu çalışmada, polietilen ve kalsiyum karnonat bileşiği (PEC) modifiyeli bitümünün sıcaklık duyarlılığı ve depolama stabilitesi incelenmiştir. PEC bitüm ağırlığınca %3, %6, %9, %12 ve %15 oranlarında kullanılmıştır. PEC modifiyeli bağlayıcıların özellikleri, %4 styrenebutadiene-styrene (SBS) modifiyeli bağlayıcı ile kıyaslanmıştır. Bağlayıcıların sıcaklık hassasiyetini belirlemek için penetrasyon, yumuşama noktası ve dönel viskozimetre deneyleri uygulanmıştır. Bağlayıcılara depolama sonrası yumuşama noktası ve dinamik kayma reometresi deneyleri uygulanmıştır. Ayrıca bağlayıcıların yaklaşık maliyetleri yardımıyla performans/maliyet ilişkisi belirlenmiştir. Deney sonuçlarına göre; %15 PEC içeren bağlayıcı düşük sıcaklık hassasiyeti ile ön plana çıkmıştır. PEC modifiyeli bağlayıcılarda %6'dan daha fazla katkı içeriğinde depolama sonrası önemli derecede faz ayrımı olduğu belirlenmiştir. Bağlayıcıların performans ve maliyetleri birlikte değerlendirildiğinde %6 PEC içeren bağlayıcının %4 SBS modifikasyonu ile sıcaklık hassasiyeti, depolama stabilitesi ve ekonomik bakımdan benzer performansa sahip olduğu tespit edilmiştir.
