“…The BBS decreases dramatically by increasing the binder thickness, where the BBS of a thick sample (binder thickness > 0.5 mm) is not affected by the mineral composition of the aggregate slab. Therefore, the BBS of the thick thickness is attributed to the binder colloid structure and is not affected by the interfacial interaction between the binder and aggregate. − …”

Rejuvenating the reclaimed asphalt binder using crumb rubber-modified binder is a sustainable paving technology that has the advantage of using waste to recycle another waste material. As binder durability is crucial in evaluating the recyclability of reclaimed asphalt using crumb rubber-modified binder, this study investigates the binder potential for aging and the impact of aging on binder bond strength. Thirty binders with different crumb rubber and reclaimed asphalt dosages were aged by rolling thin oven and pressure aging vessel and tested by Fourier-transformed infrared spectroscopy and pull-off tests. The results reveal that binder aging and reclaimed binder addition strengthen the bonding strength and elevate the carbonyl intensity, which is the keen factor responsible for bonding enhancement. However, incorporating reclaimed binders attenuates the binder aging potential and limits the bonding enhancement after aging. Crumb rubber interacts with the asphalt binder and improves the bonding strength accordingly. However, the crumb rubber interaction with the binder significantly affects the aging potential of the binder, which increases with crumb rubber disintegration and decreases with rubber swelling. As rubber swelling is the dominating interaction mechanism, the crumb rubber modification mostly undermines the bonding enhancement after aging.

“…As compared to the methods in static water immersion, the methods in dynamic water immersion simulate the scouring effect of water on the asphalt and aggregate by rotating a volumetric flask or by using ultrasonic waves to increase the severity of the test environment. These methods have been affected by subjective factors and research levels, and can be influenced by the collision between the aggregates [7][8][9]. Photoelectric colorimetry and the net adsorption test [10] both use spectrophotometers to measure the concentration change of the solution, which can then be used to evaluate the adhesion of asphalt and fine aggregates.…”

The adhesive property between asphalt and aggregate is a crucial factor that affects the resistance of asphalt pavement to moisture damage. In this study, by simulating the actual working conditions of asphalt–aggregate bonding characteristics, test equipment was developed and a method for evaluating the adhesive properties between asphalt and aggregate—the brush damage test—was proposed. A steel-wire brush as the brush type, a total of 0.5 kg/m2 asphalt content, 70 °C as the maintenance temperature, and 4 h as the maintenance time, as well as mass loss rate (ML) of specimens before and after brushing, were used as the evaluation index. The brush damage test was conducted on five commonly used asphalt binders and two commonly used aggregates. Finally, the results of the brush damage test were analyzed in comparison with those of a binder bond strength (BBS) test. It was indicated that the evaluation results for the adhesive properties between asphalt and aggregate were not consistent under the two test methods. The pull-off tensile strength under dry conditions (POTSdry) and under wet conditions (POTSwet) when ignoring the influence of the texture of aggregate did not reflect the adhesive properties. ΔPOTS, representing the ability of asphalt to resist the loss of adhesion strength due to moisture damage, can be used to evaluate the adhesion properties between asphalt and aggregate. Under appropriate conditions, the brush damage test has the advantages of simple operation, high credibility, and good discrimination.

There are abundant granite reserves in China, but the adhesion between granite and asphalt is poor, and there are problems such as insufficient water stability, which seriously restrict the application and promotion of granite in asphalt pavement. In order to improve the adhesion between granite and asphalt, as well as the water stability of asphalt mixture, amines and polymers were selected as anti-stripping agents. First, silane coupling agent modified asphalt (SCAMA), rock asphalt modified asphalt (RMA), SBS modified asphalt (SBS), and double rock composite modified asphalt (SCA&RMA) were produced; the modification effect of different anti-stripping modified asphalts was evaluated. Then, the adhesion of different types of asphalts and granite aggregates before and after aging was evaluated by time-delayed water immersion method. Finally, AC-10 and AC-16 granite–asphalt mixtures were designed, through indoor performance test and 1/3 scale accelerated loading test, evaluating the improvement effect of granite–asphalt mixture on pavement performance. The results show that the asphalt modified by amine or organic polymers anti-stripping agent could significantly improve the adhesion between granite and asphalt. The Hamburg wheel-tracking test failed to fully reflect the whole process of high-temperature rutting failure. When evaluating the high-temperature performance and water stability of asphalt mixtures, it is recommended that the evaluation method should cover the whole failure stage of asphalt mixtures; considering the coupling effect of water and high temperature, the order of water stability of granite–asphalt mixture is proposed as follows: SCA&RMA > RMA > SBS > SCAMA > 70-A, and SCA&RMA has the best modification effect.
