Abstract

Friction coefficients have a significant impact on the vibratory compaction characteristics of coarse-grained soils during road construction. This study conducted vibratory compaction simulations with varying friction coefficients and quantified the roughness of pebble particles and rubble particles using 3D scanning. Then a series of surface friction experiments were conducted. The results indicate that a higher friction coefficient had a less pronounced effect on dry density. Rubble particles generally exhibits higher roughness levels compared to pebble particles. Rubble particles exhibit much more pronounced local surface irregularities. Additionally, the friction coefficient decreased with increasing relative sliding velocity and normal pressure but increased with greater roughness. These findings reveal the relationship between friction coefficients and surface roughness, as well as the relative motion and interaction between particles. They also shed light on how these factors impact the vibratory compaction characteristics of coarse-grained soil.
