    Freeze-Thaw Splitting Strength Analysis of PAC Based on the Gray-Markov Model by Baoyang Yu, Zongguang Sun, Lin Qi

    Published 2021-01-01
    “…Through a comparative analysis of the freeze-thaw split ratio of porosities of 19%, 21%, and 24%, the PAC porosity with excellent water stability was determined to be 19–21%. Scanning electron microscopy (SEM) images of PAC with the three porosity values after repeated freezing and thawing verified that the porosities were greater than 24% and the asphalt film peeling area was the largest, resulting in the rapid decline of the PAC freeze-thaw split ratio. …”
