1. Introduction. Siliceous sand, a silicate mineral primarily composed of silicon dioxide, has been utilised as a filler in transport infrastructures, notably in highway pavements and tunnel foundations [1], [2].Recent studies by Ding et al. [3] and He et al. [4] have shown that its particle strength exceeds that of calcareous sand. Furthermore, it …
