【 摘 要 】

For designing and improving performance of porous cement stabilized macadam, design method for porous cement stabilized macadam was proposed based on Bailey method and Taibal Method. Influence on mechanical properties by different porosity and adding Polypropylene fiber were analyzed through experiment. Results show that design method for porous cement stabilized macadam, based on Bailey method and Taibal Method, could be used for designing of porous cement stabilized macadam. With porosity increasing, unconfined compressive strength and splitting strength were decreasing, and influence was significant. Adding Polypropylene fiber had little influence on porosity, but could improve unconfined compressive strength and splitting strength significantly, influence on unconfined compressive strength and splitting strength by fiber content (volume fraction) were greater, while influence by fiber length were greater on splitting strength. 1.5%o was proper fiber content and 18mm was proper fiber length.
