•Tests and numerical models study the geogrid-encased recycled aggregate columns.•A relationship between ultimate bearing capacity and relative breakage is built.•A moderate relative breakage of 4.3% leads to a smallest column-bearing capacity.•Numerical model captures the interactions between recyc...
