“…To determine the influence of temperature on the mechanical response of the asphalt mixture, the test was performed at −5, 5, and 15 °C. The reliability of the FE models has been validated in a previous investigation [22]. The computational and experimental stress–strain curves derived from the specimens under uniform load are plotted in Figure 8.…”

“…For an explicit representation of aggregate grains in the 3D model, the threshold size to distinguish coarse aggregate from fine aggregate was 2.36 mm, i.e., aggregates with a size smaller than 2.36 mm were ignored in the reconstruction process and were regarded as part of the mortar. It is worth noting that DIP techniques erode some aggregate boundaries in the binary image; thus, the area of aggregate generally shrinks in size, reducing the aggregate content as well [22]. For the construction of the FE model, shell models were first created by stacking the 2D binary images of the aggregates and air voids, as shown in Figure 6.…”

“…Increases in the temperature ranges due to climate change can increase thermal stresses in asphalt layers, and more thermal cracking can be expected [17,18]. In addition, higher temperature can lead to faster aging of asphalt mixtures, and pavements can become more prone to cracking due to brittleness [19][20][21].…”

“…Cylindrical cores are drilled from the test track with 300 mm in height and 150 mm in diameter. The details concerning the material design and the construction of the test track can be found in P. Liu et al (2018). The internal microstructure of the asphalt specimens cut close to the surface of the test track is detected through X-ray CT scanning.…”
