| The asphalt pavement on cement-bound crushed stones base produces cracks easily so that the structure of pavement is destroyed too early. On the base of a great deal of data FA has been added in to improve road-related performances of the base in the paper. By a great number of tests indoors, the theoretic analysis of microstructure and fracture mechanics, tests on the test-road, after the analysis of road-related performances of cement-bound crushed stones base and the study for improvement, the conclusion is put forward, that applying the cement FA-bound crushed stones base can obviously minish the maximal stress of asphalt pavement, lighten and stay cracks in the asphalt pavement effectively and economically so as to improve long-term performances of the structure of pavement. |
