“…[16] It is considered a green environmental material. A multitude of geopolymer performance studies [17][18][19][20][21][22] have obtained geopolymers with high strength, high-temperature resistance, acid and alkaline corrosion resistance, impermeability, excellent durability, and solidification with heavy metals. Aiken [17] studied the effects of slag powder content and activator content on fly ash geopolymer cementitious materials' sulfate corrosion resistance and concluded that geopolymer adhesive exhibits better sulfate corrosion resistance than Portland cement adhesive.…”

The application of geopolymer adhesive to CFRP-strengthened the RC structure is a new green reinforcement method, and the bonding behavior of geopolymer adhesive was studied in this paper. The geopolymer mechanical properties orthogonal test was conducted and the optimal proportion was obtained, which summarized the influence of slag powder content, liquid-solid ratio, and water glass modulus. A total of 15 adhesively bonded CFRP-concrete double-lap joints were fabricated and tested under shear loading to investigate the effect of geopolymer adhesive on the bonding behaviors. Modified bondslip models of the geopolymer adhesive specimens were developed and compared with the test date. The results showed that the failure models of epoxy adhesive and geopolymer adhesive are different. The bond strength, interface stiffness, and maximum shear stress of the geopolymer adhesive specimen can reach 93.6% ~97.6%, 95.7% ~132.9%, and 91% ~94% of the bond strength of epoxy adhesive respectively. The predicted τ max and s 0 of the proposed model are in excellent agreement with the experimental data, and the maximum deviation is À9.58%. This study proposes that geopolymer could be applied as an effective adhesive in the strengthening of RC structures.

“…The bonds are formed between the fibre and asphalt can significantly strengthen the asphalt concrete's high-temperature stability, minimal crack resistance, and water stability [39]. Qin further stated that by employing steel fibre asphalt, it was able to delay pavement degradation and cracking and extend the life of the pavement in high-traffic and cold places [40]. The asphalt mixture containing 6% steel wool fibres provides the highest strength, resistance to particle loss, and abrasion resistance [41].…”

The purpose of this paper is to overview the potential use of steel fibre in hot mix asphalt, explore the evolution of steel fibre reinforced asphalt concrete (SFRAC), highlights current trends in research and industry and recommend future areas of research. The study focus on the steel fibre industry and steel fibre generated from waste tyres applied in asphalt pavement. This review focuses on the use and performance of these fibres in altering the performance of asphalt pavements in terms of fibre concentration and fibre length, as well as the influence of steel fibre integration in asphalt pavements. According to the literature, the presence of steel fibre in asphalt pavements contributes significantly to the improvement of the properties studied, most noticeably durability. However, there are still few studies that provide conclusions about the relationship between fibre length and steel mixture concentration fibre in influencing the ability, strength, and durability properties of this asphalt concrete pavement. This review elevates awareness of the need of exploring the relationship between fibre length and morphological features in determining the bridging mechanism in asphalt concrete pavement composition.

“…e main disadvantage of cementstabilized macadam in semirigid base asphalt pavements is fatigue cracking under traffic loads over time [13]. Zhang et al [14] compared the mechanical response and fatigue damage of semirigid base asphalt pavement structure before and after repairing reflective cracks with polymer by finite element method.…”

This paper built a three-dimensional layered structure model of semirigid base asphalt pavement with single and double transverse reflective cracks based on the Extended Finite Element Method and fatigue fracture theory. The effects of the number of cracks, crack spacing, and crack length on the stress intensity factors (KI, KII, and Keff) under moving vehicle loads were studied. The fracture life of the asphalt pavement structure was calculated based on the Pairs formula. The results demonstrate that reflective cracks in semirigid asphalt pavement are composite cracks of type I and type II under moving vehicle loads, and shear fracture is the main reason for the failure of the base. The damage to the pavement base will be accelerated with the increase in the number of cracks and the length of the cracks. As the distance between the two reflection fractures is closer, the interaction between the cracks has a superimposed enhancement effect on the crack propagation. Compared with the single nonpenetrating crack model, the fatigue life of the nonpenetrating reflective crack in the double crack pavement structure with a crack spacing of 30 cm is reduced by 46.87%. The research on the propagation mechanism of reflective cracks in this paper provides the essential theoretical and numerical basis for the design, construction, working condition evaluation, and maintenance of pavement structures.
