“…The results were in accordance with other researches in that the rutting performance of the NR modified bitumen was improved compared to the base bitumen. It was also found that the ZycoTherm material was uniformly dispersed in the bitumen matrix and the NR-modified bitumen with ZycoTherm exhibited excellent rutting resistance [10].…”

“…Peningkatan kekuatan campuran ini diperkirakan karena penambahan lateks memperbaiki karakteristik aspal. Hal ini didukung oleh Usman et al (2019), Sani et al (2019), Kamal et al (2020), dan Abdulrahman et al (2020), yang menyatakan bahwa bahan lateks mampu memperbaiki sifat aspal, yaitu nilai penetrasi, titik lembek, stiffness, viskositas, dan ketahanan terhadap rutting.…”

This paper presents the results of research on the durability of Asphalt Concrete-Wear Asphalt (AC-WC) mixture using latex material to water immersion. Resistance to warm water immersion is intended to measure the durability of asphalt mixture in serving traffic loads against the influence of water and temperature factors. The use of latex material is intended to improve the performance of the mixture. This research uses a laboratory-scale test. The specimen of AC-WC added with latex was tested for its tensile strength using the Indirect Tensile Strength (ITS) test. Other specimens are immersed in water at 60°C with a continuous and periodic soaking system. The continuous immersion was carried out for 0, 24, 48, and 72 hours, while the periodic immersion was carried out for 12 hours soaked and 12 hours exposed alternately. The durability was analyzed using the Residual Strength Index indicator. The analysis shows that the addition of latex increased the tensile strength of the AC-WC mixture based on the ITS test results. The AC-WC mixture added with latex can increase its resistance to continuous and periodic immersion, by increasing the residual strength index and decreasing IKS with increasing immersion time. Continuous immersion has a greater impact on reducing IKS than periodic. In specimens without latex, the decrease in IKS values between continuous and periodic soaking has the same pattern, but in specimens with latex, the pattern is different. Keywords: asphalt concrete; latex; water immersion; Indirect Tensile Strength; Residual Strength Index. Abstrak Makalah ini menyajikan hasil penelitian mengenai ketahanan campuran beraspal Asphalt Concrete-Wearing Course (AC-WC) yang menggunakan bahan lateks terhadap rendaman air. Ketahanan terhadap perendaman air hangat dimaksudkan untuk mengukur daya tahan campuran aspal dalam melayani beban lalu lintas terhadap pengaruh faktor air dan temperatur. Penggunaan bahan lateks dimaksudkan untuk memperbaiki kinerja cam-puran. Penelitian ini menggunakan uji skala laboratorium. Kekuatan tarik benda uji AC-WC dengan lateks diuji menggunakan uji Indirect Tensile Strength (ITS). Benda uji yang lain direndam dalam air bertemperatur 60oC dengan sistem rendaman menerus dan rendaman berkala. Metode perendaman secara menerus dilakukan selama 0, 24 jam, 48 jam, dan 72 jam, sedangkan rendaman secara berkala dilakukan 12 jam direndam dan 12 jam diekspose secara bergantian. Tingkat keawetan dianalisis menggunakan indikator Indeks Kekuatan Sisa (IKS). Hasil analisis menunjukkan bahwa penambahan lateks meningkatkan kekuatan tarik campuran AC-WC berdasarkan hasil uji ITS. Ketahanan terhadap perendaman menerus dan berkala, campuran AC-WC menggu-nakan lateks meningkat, dengan meningkatnya indeks kekuatan sisa dan menurunnya IKS dengan bertambah-nya lama rendaman. Perendaman secara menerus memberi dampak yang lebih besar dalam menurunkan IKS dibanding perendaman berkala. Pada benda uji tanpa lateks, penurunan nilai IKS antara rendaman menerus dan rendaman berkala memiliki pola yang sama, namun pada benda uji dengan lateks pola penurunan nilai IKS berbeda. Kata-kata kunci: campuran beraspal; lateks; rendaman air; Indirect Tensile Strength; Indeks Kekuatan Sisa.

“…Previous research has shown that the implementation of recycled crumb rubber and natural rubber latex biopolymer as asphalt modifers improves the performance of road surfacing materials [1][2][3][4].Rubber-modifed asphalt mixture has superior resistance to rutting, thermal cracking, fatigue damage, and stripping and lower temperature sensitivity [5][6][7]. Compared to the conventional asphalt binder, using natural or synthetic polymers has signifcantly enhanced the binder properties [8,9].…”

Asphalt mixture modification with rubberised material frequently results in improved characteristics and extended service life in actual application. This research characterised the synergistic consequences of rubber modifiers (crumb rubber powder (CRP) and natural rubber latex (NRL)) and wax-based admixtures (Tough Fix Hyper (TFH)) on the performance of the asphalt mixture from the fracture energy and laboratory fracture resistance perspectives. Semicircular bending (SCB) and indirect tensile strength (ITS) tests were conducted to assess the fracture properties of the asphalt mixture samples. To prepare asphalt mixture samples, the wet method was utilised. Higher CRP levels resulted in greater strength and a longer time to attain peak force for both control and mixtures containing wax admixture, as determined by SCB. The interaction between the higher CRP or NRL content and the TFH additive enhanced the fracture resistance, indicating that the components are highly compatible. The 10L + TFH additive produced the highest fraction of energy, indicating a more significant improvement than the counterpart mixes containing the CRP modifier. In addition, incorporation of the CRP and NRL increased the fracture plastic zone (FPZ), resulting in increased fracture toughness. Therefore, the gradient of fracture toughness and fracture energy in the asphalt mix depends on the rubber type, content, and TFH. Although the higher CRP, NRL, and TFH improve the fracture energy and cracking resistance, they increase the crack initiation and propagation velocities, whereby the high bitumen stiffness makes the mixture more brittle than the control mixture. Caution should be exercised when selecting the content of rubber modifier and TFH for the asphalt pavements in low-temperature service. Also, there is a direct interconnection between fracture resistance and fracture energy in the mixtures containing CRP, NRL, and TFH. Such correlations can be used as the premise of predictive micro- and macro-models to evaluate mixture performance in terms of fracture resistance.
