Semi-resolved CFD-DEM modeling of pore clogging in pervious asphalt concrete

Year: 2026

Type: article

Abstract: Pervious concrete and asphalt concrete suffer from permeability loss due to particle clogging, yet the underlying mechanisms remain poorly understood. This study employs a novel semi-resolved CFD-DEM approach to efficiently simulate fluid-particle-pore interactions in permeable pavements. Validated against experiments, the method accurately captures clogging dynamics. Numerical simulations explore varying particle concentrations, sizes (spherical/ elongated multi-sphere), and pore structures, revealing a universal scaling law for clogging ratio evolution. The proposed framework enables rapid assessment of permeability degradation and offers design insights for enhanced pavement durability and drainage performance.
