Abstract

This article is based on the practical engineering need of expressway .Study about the mechanical properties of phyllite filler, and then improve the property by using the cement. Testing the original rock phyllite minerals analysis experiment, uniaxial compressive strength test and physical parameters of phyllite filling test and water disintegration test and analysis. After that we make test about different gradation of the cement improved phyllite packing compaction test and unconfined compressive strength test, analyzed the change characteristics of modified phyllite filler engineering, comprehensive analysis and selection of cement admixture is 3%, content of coarse aggregate gradation is 55%.This is the best combination to meet the requirements of economy and the mechanical properties.
