“…10(c)-10(d). Air voids in dense-graded asphalt mixture are clearly the most important factors in freeze-thaw damage [1,3]. A higher level of air voids always provides more space for water retention.…”

“…At high temperatures, the water absorbed in the porous network can expand even more than the surrounding material itself, resulting in an increase in the linear coefficients of thermal expansion and in a stiffness reduction of the asphalt mixture. On the other hand, when water freezes within the voids of an asphalt mixture, this leads to (a) a significant stiffness increase, (b) a sudden change of the shift factor evolution above and below the freezing point, and (a) a volumetric expansion generated by a water phase change that will induce damage . For example, after the partially saturation of samples, Quebec test method LC 26‐001 and standards ASTM D 4867 and AASHTO T 283 specified a conditioning in water at 60 ± 1°C for a period of 24 ± 1 hour.…”

This paper analyses the water, the degree of saturation, and the void content effects on the fatigue behaviour of hot mix asphalt (HMA) samples mixed in the laboratory. Some results on stiffness are also given. Fatigue characterization was carried out through a uniaxial tension-compression (T-C) test performed in a controlled-strain mode, at 10°C and 10 Hz, on cylindrical samples. Our results show that the stiffness is not significantly affected by the water. This finding could be attributed to the short period of immersion of samples in water, low testing temperature, low void content of tested samples, and high viscosity of bitumen used. Furthermore, the fatigue resistance of HMA partially saturated with water (PSW) is lower than the one obtained for dry materials.

“…Compared with the continuous-graded AC-13 asphalt mixture, the gap-graded SMA-13 asphalt mixture exhibits better resistance to freeze-thaw damage under complex stress conditions. This is mainly because SMA-13 is a framework-dense structure and AC-13 is a suspend-dense structure, the SMA-13 asphalt mixture consists of a coarse aggregate skeleton which has a high binder content and a low air void content, and there are some fibers in the mixture [31][32][33]. Since the influence of freeze-thaw cycling and complex stress conditions are inevitable in the middle and lower reaches of the Yangtze River and some seasonally frozen areas of China in winter, the SMA-13 asphalt mixture is recommended to improve the resistance to freeze-thaw erosion.…”

In order to study the influence of freeze-thaw cycles on the multi-axial strength of AC (Asphalt Concrete)-13 and SMA (Stone Mastic Asphalt)-13 asphalt mixtures which are widely used in China, triaxial tests were carried out in the laboratory. Two nonlinear failure criterions under three-dimensional stress states in octahedral space were established. A linear model for engineering design and its simplified testing method were then presented. The three-dimensional failure criteria of asphalt mixtures after 0, 1, 3, 5, 10, 15, 20 freeze-thaw cycles were also proposed. The results indicated that the multi-axial strength decayed significantly after 20 freeze-thaw cycles. It is noteworthy that the strength degrades rapidly during the first 5 freeze-thaw cycles. Compared with AC-13 asphalt mixture, the SMA-13 asphalt mixture exhibits better performance on the resistance to freeze-thaw damage, and it is recommended as the upper surface layer material of pavement structure.
