“…A high flow value represents the mixture with a low resistance of deformation, while a low value indicates the mixture with high deformation resistance. Thus, the low flow value deformed less after the load was applied [21].…”

The number of transport or vehicles on the road is increasing, which cause the road pavement or asphalt surface exposed to greater loading. Problems such as permanent deformation, cracking, fatigue, and skidding happened because of this repeated loading. There are many studies have been done to determine the suitable waste materials that can be used in order to improve resistance to rutting and fatigue cracking due to filler hardening and improve adhesion of filler to aggregate. The aim of this study is to investigate the effect of CBA on engineering properties of asphalt mixture. The different percentages of CBA (0%, 2%, 4% and 6%) were added to the asphalt mixture. The 60/70 penetration grade asphalt was used. The performance of the samples was evaluated through Marshall Stability, indirect tensile strength, resilient modulus, dynamic creep and image analysis. From the result obtained, there are significant effect comes from the addition of CBA. The result show that the addition of CBA in range of 2 to 4% produces the best outcomes for the density, stability, stiffness and flow while 6% for indirect tensile strength, dynamic creep and resilient modulus. Thus, it can conclude that the existence of CBA can enhance the performance of asphalt mix.

“…In the meantime, a few studies have been conducted on using waste toner as an asphalt binder modifier. Based on laboratory studies, Notani et al [ 7 ] found that adding 12% of waste toner can improve the rutting resistance of asphalt binder and mixtures. This finding was confirmed by Huang et al [ 8 ] who added that by using it as a value-added modifier in the pavement construction industry, not only were the properties of asphalt enhanced, but also the disposal waste toners were recycled in an environmental way.…”

The growing amount of waste toner (WT) has posed a significant environmental challenge. Meanwhile, researchers are interested in the feasibility of utilizing waste toner as an asphalt binder modifier because its primary chemical components (Styrene-acrylic copolymer and carbon black) are known to improve asphalt properties. The objective of this study was to evaluate the chemical and rheological properties of the waste-toner-modified asphalt binder and hence determine the suitability of integrating waste toner for asphalt modification. The waste-toner-modified asphalt (TMA) binders were produced by blending base asphalt with two types of waste toners of different gradation sizes. Microscopic tests such as x-ray fluorescence (XRF), attenuated total reflectance transform infrared spectroscopy (ATR-FTIR), and scanning electron microscopy with energy dispersive X-ray (SEM-EDS) and fluorescence microscope, as well as rheology tests such as multiple stress creep recovery (MSCR) tests, oscillation tests, and bending beam rheometer tests were performed. The FTIR results showed that there was a chemical reaction between waste toners and base asphalt binder. A fluorescence effect was observed on the binders produced with different toners used in this research. The binder modified with an optimal content of 8%WTs revealed better high and low-temperature properties. Additionally, 8%WTs used in this research could change the PG70-22 binder to PG76-22 binder. The rutting properties of asphalt material were improved for its improved elasticity. In addition, the 200-mesh TMA binders were desirable with respect to waste toner particle size. Overall, there is a benefit to using waste toner in the asphalt industry.

“…Rutting or permanent deformation is one of the most common distresses in flexible pavements. It shows permanent longitudinal depressions in the wheel paths, sometimes with minor upheavals to the sides [1][2][3][4]. Densification and shear deformation of asphalt mixes are the main mechanisms for rutting.…”

The Shear Tester with Normal Stress (STNS) is developed in this study for measuring the fundamental shear properties of asphalt mixes at a low cost. The device can shear an asphalt concrete specimen subjected to controlled normal stress of 113 kPa (16.35 Psi). A total of 72 test specimens of three asphalt mixes, produced at different daily times, were tested for the Frequency Shear Test at Normal Stress (FSNS) and Repeated Shear Test at Normal Stress (RSNS). The FSNS test was used to measure the dynamic shear modulus |G*| and shear phase angle (δ), whereas the RSNS test was conducted to measure the permanent shear deformation for asphalt mixes. The results showed that the average values of the measured |G*| and (δ) have generally the same trends over the shear load frequencies for all mixes. All sample groups have average permanent shear deformations of less than 1.1 mm at 5000 repeated shear loads. The shear phase angle had comparable variabilities to that of the dynamic shear modulus at high shear load frequencies. The measured permanent shear deformations had variabilities of less than 17% for all mixes.
