Abstract The shape of particles plays a significant role in determining the mechanical properties granular materials. This study explores how morphology crushed stone affects its deformation characteristics during compaction. Granite stones were analyzed using 3D particle measurement system and image processing techniques to assess their sphericity, flatness, factor across four size groups: 5–10 mm, 10–15 15–20 20–25 mm. Compaction tests conducted hydraulic universal testing machine evaluate stress-strain relationships. results indicate that parameters, such as sphericity vary with size, curves compaction follow an exponential function. Tetrahedral exhibited highest under identical stress conditions, while hexahedral demonstrated lowest deformation. Field − 1465 m belt roadway chamber Sha-ling Gold Mine validated theoretical model, emphasizing heterogeneity fractured rock masses excavation-induced adjustments. These field essential confirm reliability analysis.

The rapid expansion of highway infrastructure in the mountainous regions China has led to a significant increase tunnel construction, generating substantial amounts waste slag. Concurrently, development transportation created critical shortage natural aggregates, necessitating exploration alternative sustainable sources. This study aimed conduct comprehensive evaluation physical and mechanical properties slag explore its potential for utilization cement-stabilized base courses engineering applications. uniaxial compressive strength parent rock (tunnel slag) ranged from 81 MPa 89 desiccated state, indicating suitability use as construction material. also determined maximum dry density (2.432 g/cm3) optimal moisture content (5.4%) mixtures incorporating recycled aggregates derived splitting tensile these at 28 days varied 0.48 0.73 MPa, demonstrating robust performance. Moreover, unconfined escalated 7.0 7 11.0 90 days, signifying enhancement over time. These results validate viability utilizing furnish valuable insights designers, concrete manufacturers, firms engaged aggregate courses.
