Abstract: | Through indoor experiment,this paper studies the influence of polypropylene fiber on the compressive strength,tensile strength and static resilience modules of cement stabilized semi-rigid crushed-stone base material.The result indicates that fibre can improve the strength of cement stabilized crushed-stone base on a certain basis and can effectively reduce resilience modules,favorable for improvement of deformation resis-tance of foundation. |

Keywords: | cement stabilized crushed stone semi-rigid material polypropylene fiber indoor experiment |
