This paper aims to accurately measure the fatigue performance and calculate the fatigue life of fiber-reinforced asphalt concrete (FRAC). Firstly, splitting fatigue tests were conducted under the stress control mode. Through the tests, the attenuation features of the FRAC stiffness modulus were analyzed with different fiber contents and length-todiameter ratios. Drawing on damage mechanics theory, a fatigue failure criterion was put forward for the FRAC. Based on stress ratio-fatigue life (S-N) equation, the authors established a calculation model for fatigue life of the FRAC, in the light of the characteristic parameter of fiber content (FCCP). The results show that, the FCCP can reflect the combined effect of fiber content and length-to-diameter ratio on the fatigue performance of the FRAC; With the growth of the FCCP, the FRAC fatigue life always increased first and then decreased; The FRAC realized the longest fatigue life, and achieved the best fatigue performance at the FCCP of 1.13; For AC-13 polyester FRAC (PFAC), the fiber content, length-to-diameter ratio, and the FCCP were optimized as 0.35%, 324, and 1.13, respectively. The research results provide new insights to the fatigue performance of the FRAC.

“…5,6 Fatigue cracking is one of the most affected by moisture because of water and the origins of cracks at the aggregate-binder interface, air voids, or mastic. [7][8][9] Asphalt mixtures are constituted of mineral aggregates (elastic response particles) and asphalt binder (viscoelastic response material). 2,10 The overall composite presents a thermo-viscoelastic behavior.…”

“…Even though the testing methods are not new, 18,19 it is important to notice that fatigue investigations considering simultaneously moisture effects and the different material scales are not observed in the present literature. Some authors focus on asphalt mixture behavior as it relates to Indirect Tensile Strength, [20][21][22][23] Dynamic Modulus, 24,25 Fatigue 8,24,26,27 ; while others use different techniques to comprehend the interface itself, 11,28,29 or to study binders 30 and aggregates individually, or even still as interfaces in an attempt to assess the overall mixture's behavior. 13,14,22 The objective of this work is to evaluate the moistureinduced damage of asphaltic materials at different material scales (asphalt binder, aggregate-binder interface, and asphalt mixture).…”

Fatigue cracking, a major distress in asphalt pavements, is worsened by traffic and climate conditions such as moisture effects on constituents and interfacial properties. However, investigation on fatigue's evolution in different scales under moisture effect is still scarce in the open literature. This work aims to assess moisture‐induced damage effects on asphaltic materials focusing on the failure of asphalt binders, the aggregate‐binder interface, and mixture. The methodology included tests under dry and wet conditions: linear amplitude sweep (LAS); asphalt bond strength (ABS) in different temperatures and pull rates for interfaces; indirect tensile strength (ITS), and tension‐compression fatigue on asphalt mixtures. Key findings were: (i) moisture damage presents growing effects from binders to mixtures; (ii) LAS test results were not sensitive to moisture; (iii) ABS tests require proper field temperatures for accuracy; (iv) ITS ratio provide reliable conditioned fatigue expectations; and (v) fatigue testing without conditioning to hydrodynamic effects or real moisture susceptibility might overestimate service‐life.

“…Cooper and IPC fatigue testing machines can obtain lag angle and dissipated energy, which is beneficial to fatigue test research and analysis. Di Benedetto, Cardona DR, Sébastien Lamothe, Zhiyong Wu, Yang Panpan and other scholars studied the fatigue performance of asphalt mixture using dissipated energy, lag angle, cumulative dissipation energy and the ratio of dissipated energy change methods [ 22 , 23 , 24 , 25 , 26 , 27 , 28 ].…”

The fatigue resistance of asphalt mixture is an important indicator to evaluate the durability of asphalt pavement. In order to improve the fatigue properties of asphalt mixture, diatomite and environmental basalt fiber were added. Four types of asphalt mixtures, ordinary asphalt mixture (AM), diatomite modified asphalt mixture (DAM), basalt fiber modified asphalt mixture (BFAM) and diatomite/basalt fiber composite modified asphalt mixture (DBFAM), were chosen, whose optimum asphalt–aggregate ratio, optimum content of diatomite and optimum content of basalt fiber could be determined by Marshall test and response surface methodology (RSM). The multi-functional pneumatic servo Cooper test machine was carried out by a four-point bending fatigue test. Through the comparative analysis of flexural-tensile stiffness modulus (S), initial stiffness modulus(S0), residual stiffness modulus ratio, lag angle (ϕ) and cumulative dissipation energy (ECD), the fatigue resistance of asphalt mixture can be effectively improved by adding diatomite and basalt fiber. Grey correlation analysis was also used to analyze the degree of correlation between the fatigue life and the influencing factors such as VV, VMA, VFA, OAC, S, and ECD. The analysis results indicate that ECD has the greatest impact on the fatigue life of the asphalt mixture.
