air entrained cellulose fiber pavement concrete was prepared by adding cellulose fiber and air entraining agent to ordinary pavement concrete,then test for compressive strength and flexural strength. Based on the RSM method, the experimental results were modeled by using the Design Expert statistical analysis software. This paper researches the notability degree of air content and cellulose fiber content the intermingled influence between them towards the mechanical properties of concrete. The results show that, the notability degree effects of air content on compressive strength of concrete is remarkable, but the notability degree effects of cellulose fiber content is weak; The interaction between air content and cellulose fiber content has no significant effect on compressive strength; the notability degree effects of air content on rupture strength of concrete is slightly greater than that of cellulose fiber; The interaction between air content and cellulose fiber content has significant effect on rupture strength;
