May 1, 2021The HHCM and QSCM cannot fully simulate the influence of the construction site vibration roller on the compositional structure of UGAM. Moreover, the mechanical strength of the QSCM specimen is less than 50% of the field-measured mechanical strength, thus the QSCM is unlikely to simulate the true mechanical response of the UGAM base [25], [26].
