To study the effect of double mixing of waste rubber and fly ash on the strength and water permeability of pervious concrete, this paper adopts an orthogonal experimental design, aiming at exploring an optimal range between the mixing amount of waste rubber and fly ash by analyzing the effect of different mixing amounts of the two on the compressive strength and water permeability coefficient of the pervious concrete and analyzing the design of the mixing ratio with an optimized balance of strength and water permeability coefficient. The results show that an appropriate amount of fly ash can improve the compactness and compressive strength of concrete, but too much will reduce the compressive strength. Waste rubber can increase the compressive strength within a certain mixing range, but too much will reduce it. The water permeability coefficient decreases with the increase in the dosage of waste rubber and fly ash. It was found that the best overall performance of pervious concrete was achieved when the water-cement ratio was 0.28, at 15% fly ash and 10% waste rubber. This study provides a new type of road material for the practical application of previous concrete, which helps to solve the problem of waste tire pollution and promotes the development of green building materials.
