Abstract

This article selected the phyllite of the eastern Ankang section of the highway from Shiyan to Tianshui for raw materials,and made a series of experiments. The results showed that phyllite belongs to a kind of soft rock, low strength ,stability, and easy to collapse .This article is based on CBR test results,combined with analysis of variance theory analyzes the different cement dosage and coarse aggregate level matching phyllite packing effect of CBR.The results showed that the dosage of cement and coarse aggregate level matching phyllite CBR value effects are significant.When considering the economic and engineering characteristics,through the analysis,the choice with 3% the cement dosage and 55% the content of coarse aggregate of gradation combination is the best combination.
