“…The I C=O of the layer 1 in 90A was greater than that of control during 4-144 h, indicating that moisture erosion caused oxidation of asphalt surface and produced more aging functional groups. Because asphalt can react with oxygen molecules from the water leading to oxidation of asphalt surface [29]. The I C=O of each layer inside asphalt increased gradually with the extension of erosion period, however the increasing rate decreased step by step from the surface to the inside, which might be caused by the diffusion of eroded asphalt.…”

“…The range of scan wave number was from 4000 cm − 1 to 400 cm − 1 and the scan time was 64 times. Although water can block oxygen from the air to some extent, asphalt can react with oxygen molecules from the water leading to asphalt oxidation during immersion [29]. And the dissolution and migration of asphalt also occur due to the existence of water [30].…”

“…The oxidation reaction of asphalt with oxygen molecules in water can produce the polar molecules [20,29]. Due to the polarity of water, the polar components in asphalt are more likely to be dissolved and migrated, resulting in a gradual reduction of polar components during immersion [30].…”

“…Meanwhile, the inherent capacity of noncapsule beams to recuperate their strength was observed to diminish upon the implementation of water solution treatment. The reason is that the intrusion of moisture leads to a reduction in cohesive force between asphalt layers and the adhesion stress between asphalt and aggregate [6,45,46]. The salt (NaCl) and alkali solution (NaOH) have an obvious adverse effect on the natural healing ability of asphalt concrete.…”

Polymer Ca-alginate capsules with rejuvenator bring a high healing level for asphalt concrete under dry healing environments; however, the healing levels of bituminous mixtures containing capsules under water healing conditions are still unknown. In view of this, this study aimed at exploring the healing levels of asphalt concrete containing polymer capsules under various solution healing conditions following cyclic loads. This study involved the preparation of capsules, followed by the evaluation of their morphological characteristics, resilience to compression, thermal endurance, and rejuvenator content. The assessment of the healing properties of asphalt concrete utilizing capsules was conducted through a fracture–heal–refracture examination. This study conducted Fourier transform infrared spectrum experiments to determine the rejuvenator release ratio of capsules under dry conditions and the remaining rejuvenator content in extracted bituminous binder from capsule–asphalt concrete after solution treatment. Meanwhile, a dynamic shear rheometer was utilized to investigate the rheological characteristics of asphalt binder. Results revealed that the healing ratios of capsule–asphalt concrete beams under a dry healing environment were significantly higher than that of beams under various solution healing conditions, and the alkali solution has the worst effect on the improvement in healing ratio. The coupled impact of moisture intrusion and ion erosion resulted in an enhancement of complex modulus of asphalt binder while concurrently reducing its phase angle. Consequently, the restorative capacity of the asphalt binder was weakened.

“…Chemical alterations produced during mixture aging point to modifications in the bituminous-binder molecular structure increasing their stiffness and cracking potential [10]. PA mixtures are affected by severe long-term aging due to their open structure, which allows binder oxidation through the whole pavement structure [13], resulting in premature aging [7]. Additionally, other environmental conditions, such as solar radiation, contribute to the aging of PA mixtures, making them brittle and increasing their raveling potential [14].…”

Porous asphalt (PA) mixtures have become a common and very useful pavement technology for preventing dangerous driving conditions in wet weather and as a permeable surface in permeable pavement systems due to their capacity to filter water. The increased social awareness of sustainability matters has expanded the interest in reducing the impact of construction materials on the environment, mainly by using recycled materials in their composition and, hence, reducing the depletion of raw materials. In this research, two innovative recycled filler materials, namely, cellulose ash (CA) and combustion soot (CS), have been used as a total filler replacement in PA mixtures to look for improved mechanical strengths and characteristics. Four different filler dosages were assessed for each filler material, and the produced PA mixtures were tested for their particle loss, water sensitivity, freeze–thaw durability, Marshall stability, resilient modulus and permeability in order to obtain a full picture of their performance. The obtained results showed that both filler materials, adequately dosed, can generate PA mixtures that significantly overcome reference mechanical values for PA mixtures that maintain adequate infiltration capacities to satisfy the main international standards, proving to be suitable replacements for conventional filler materials commonly used in asphalt mixture production.
