Abstract:
In order to determine the optimum material composition to satisfy the design criteria of erosion in the project, gray system theory was applied to predict the value of erosion of cement-stabilized macadam material, the fractal dimension of aggregate, 28 d strength of cement mortar, cement dosage and water dosage were selected as modeling parameter, the erosion predict model of cement-stabilized macadam was established, and the simplified formulae of the 28 d erosion predict model for two different kinds of structure of cement stabilized macadam were proposed, which are suspend-dense structure and framework-dense structure respectively. Applicability tests show that the error of the predict value with measured value is small, that indicates the 28 d erosion predict model of cement stabilized macadam is reasonable. 3 tabs, 6 figs, 10 refs.
