In order to improve the applicability of pervious concrete in the seasonal frozen region,and exploit the utilization value of sustainable materials,orthogonal design was used to explore the strength and freeze-thaw damage of glass rubber composite permeable pavement.The results show that the high-quality mix proportion based on lightweight permeable concrete pavement is porosity of 20％,water cement ratio of 0.26,rubber particles of 6％,and glass powder of 20％.The freeze-thaw durability test conducted on different permeable concrete samples show that the permeable concrete with composite doping of glass powder and rubber particles had an average increase of 13.93％and 38.82％in frost resistance compared to the single-doped rubber particle and control groups.The modified compound pervious concrete can combine permeability and strength performance to meet the mechanical performance and durability requirements while achieving the goal of reducing ecological pressure and production costs,which has important application value in the field of road construction and sustainable development.
