Research on way-use performance for powder soil as road subbase course

Through studying the method of special powder soil was made of highway subbase, a kind of suitable steady type on mechanics and way-use performance was found, joined materials had mainly cement and pulverized coal ash and lime in the experiment, from joined alone these materials to mix jointly to find the optimal fit material, finally, through contrast tentative data to verify separately mixture qualitative way-use performance, useful reference data was provided for vast users in future.
