%X Conventional asphalt binder is widely used to produce asphaltic concrete mixtures. The rheological weakness of conventional asphalt binder has developed an interest among researchers in modifying conventional asphalt binder by using various kinds of additives. Bonding promoters are used as additives in asphalt binder that have shown a significant effect in enhancing the physical and rheological properties as well as its performance. This study aims to enhance the coatability of modified asphalt binder and bonding characteristics by using bonding promoters, namely polyalkylene glycol-based (PLG) and alkylamines-based (ALM). The laboratory study was divided into three phases. The first stage involved the determination of the physical properties and performance of modified asphalt binders. The coatability index was evaluated in the second phase, whereas the third stage evaluated the asphalt-substrate bonding performance. The physical properties showed that incorporation of bonding promoter reduces the penetration values, which indicates the increment of the ability to stiffen the binder. However, the penetration grade of all modified binders is still within 60/70. Meanwhile, the incorporation of bonding enhancers increased the modified binders� rutting performance via DSR test by over 40 for 0.5 ALM. In terms of coatability performance, the static water immersion test shows insignificant changes resultant from the addition of PLG and ALM. Moreover, under the action of boiling sodium carbonate, the coatability index of all modified asphalt binder reduces as it is used to accelerate the moisture damage effect. Lastly, both bonding promoters can improve tensile strength and resist shear stress according to asphalt-substrate bonding performance. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd 2024.
