Preestimate the intensity of rock-soil aggregate mixture quickly and accurately is not only helpful to design and calculate

but also to establish the construction scheme and choose properly compaction method

while the rock-soil aggregate mixture are broadly used in roadbeds

dykes and dams

and foundation engineering. The physico-mechanical character of the mixture are essentially determinated by the granule property of the mixture and the interior frame of the mixture

but the classification existed are always set about from the grain composition

it is hardly to predict the character of the mixture from the classification. Aimed at the engineering application

studied the classification method of the mixture supported by the results of lab shear test and compaction test

and utilized the nonlinear theory of fractal geometry

this article assorted the mixture into 3 levels and 24 kinds according to the property of rock and soil

the ratio of rock to soil and the granularity distribution fraction dimension of the mixture

to present the diversity on characters of different kinds of mixtures meanwhile. This synthetical classification method is prone to apply in practice for the criterion of this method is simple and it can be determined conveniently; and the representative strength of different kinds of mixtures could be quickly predict through this classification method.
