Abstract:

The paper analyzed the phyllite properties in the highway from Shiyan-Tianshui the eastern An-kang 25th section through the related indoor and outdoor testing. As the on-site filler CBR value didnt meet highway subgrade filling on the filler mechanical properties, and it should be improved with cement. The engineering and compaction properties were analyzed under different cement doses and gradation combinations, whose result was shown that selecting the improved phyllite gradation composition of 5% cement content and 60% stone content was the optimal. In that it could not only meet subgrade strength design requirement and the on-site application, but also be the most economical and reasonable.
