“…The greater the energy, the greater the plastic deformation and crack intensity [44]. AE energy is superior to other parameters in PAM damage identification owing to its high sensitivity to amplitude and duration [43]. In addition, the AE signal at low temperatures is more significant than that at room temperature [45].…”

Porous asphalt mixtures with steel slag (PAM-SS), as an eco-friendly and low-cost pavement material, are conducive to addressing the issue of urban floods and natural resource shortages. The primary objective of this paper was to explore the feasibility of the application of PAM-SS for seasonal frozen regions, and ascertain the optimal replacement percentage of natural aggregate. Steel slag coarse aggregate (SSCA) was used to replace basalt coarse aggregate (BCA) at four levels (25%, 50%, 75%, 100%) by equal volume. The volume characteristics, mechanical properties, low-temperature cracking resistance, water stability, and freeze-thaw (F-T) durability of the mixture were assessed. The results indicated that the low-temperature cracking resistance of the mixture was significantly enhanced and acoustic emission (AE) energy was uniformly released by the incorporation of steel slag. Furthermore, the porosity, permeability, Marshall stability (MS), and the resistance against water damage and F-T cycles were also significantly improved. Based on the experimental results, the complete replacement of natural aggregate is advisable to obtain an optimal overall performance.

“…Nowadays, some studies demonstrated the feasibility of the AE technique in PAM with heterogeneity and stone-on-stone interlocked structure, and reported that AE possesses great potential in real-time crack monitoring and fracture characterization of PAM, especially in complicated environments. Jiao et al [ 37 , 38 ] investigated the damage evolution and fracture modes of PAM under low-temperature splitting with the aid of the AE technique. Cai et al [ 39 ] found that the incorporation of lignin fiber can significantly delay the growth of shear cracks along the interface under uniaxial compression by employing the AE technique, and stated that AE can effectively compensate for the deficiency of mechanical experiments and theoretical models.…”

Acoustic emission (AE), as a nondestructive testing (NDT) and real-time monitoring technique, could characterize the damage evolution and fracture behavior of materials. The primary objective of this paper was to investigate the improvement mechanism of steel slag on the low-temperature fracture behavior of permeable asphalt mixtures (PAM). Firstly, steel slag coarse aggregates were used to replace basalt coarse aggregates with equal volume at different levels (0%, 25%, 50%, 75%, and 100%). Then, the low-temperature splitting test with slow loading was used to obtain steady crack growth, and the crack initiation and propagation of specimens were monitored by AE technique in real time. From the low-temperature splitting test results, SS-100 (permeable asphalt mixtures with 100% steel slag) has the optimal low-temperature cracking resistance. Therefore, the difference of fracture behavior between the control group (permeable asphalt mixtures without steel slag) and SS-100 was mainly discussed. From the AE test results, a slight bottom-up trend of sentinel function was founded in the 0.6–0.9 displacement level for SS-100, which is different from the control group. Furthermore, the fracture stages of the control group and SS-100 could be divided based on cumulative RA and cumulative AF curves. The incorporation of 100% steel slag reduced the shear events and restrained the growth of shear cracking of the specimen in the macro-crack stage. Finally, the considerable drops of three kinds of b-values in the final phase were found in the control group, but significant repeated fluctuations in SS-100. In short, the fracture behavior of PAM under low temperature was significantly improved after adding 100% steel slag.

“…In order to further understand the damage effects of F-T cycles on specimens, acoustic emission technology was also used during the splitting test. Acoustic emission technology, as a damage detection technology, has been gradually applied to the field of asphalt mixtures in recent years [29,30]. During the experiment, the surface of the acoustic emission sensor was evenly coated with coupling agent, and then the sensor was clamped on the surface of a test piece with a rubber band.…”

Experimental Study on the Performance Decay of Permeable Asphalt Mixture in Seasonally Frozen Regions under Freeze-Thaw Cycles

et al. 2020

This paper focuses on the freeze-thaw cycles (F-T cycles) resistance of porous asphalt mixture (PAM) with different air voids in order to explore the gradation of the PAM suitable for seasonal freezing regions. Three sets of PAMs with 18%, 21%, and 25% air voids were designed. After 0–20 F-T cycles, the effects of F-T cycles on the performance degradation of three groups of PAMs were studied by performing a low-temperature splitting test with acoustic emission technology, a normal temperature splitting test, a compression test, a Cantabro particle loss test, and a dynamic creep test. The results show that the damage process of PAM caused by multiple F-T cycles could be more clearly defined by acoustic emission parameters. In addition, the larger the air void, the smaller its indirect tensile strength and compression strength, and the worse its particle loss resistance and high-temperature stability, which made the adverse effect of F-T cycles more significant. Therefore, the air void of PAM used in seasonal freezing regions is suggested to be less than 21%.
