Abstract: Cement stabilized gravel is a semirigid material obtained by adding cement and water to a certain grade of gravel.The stabilized soil has better water stability and frost resistance than that of lime stabilized soils. In recent years, there have been many researches on the nonlateral compressive strength of cement stabilized gravel mixed with single fiber, and there is less researches on the compressive strength of cement stabilized gravel mixed with mixed fibers. Therefore, in order to study the relationship between the unconfined compressive strength of basaltglass mixed fiber cement stabilized gravel and the mechanism of improving the stability. By changing the content of basalt fiber and the content of glass fiber in the cement stabilized gravel, the unconfined compressive strength of the 25 mm basalt gravel size mixed with 1.0‰ fiber and the 12 mm basalt gravel size mixed with 0.8‰ fiber will have a maximum unconfined compressive strength of 4.63 MPa.
