Discuss on Highly Weathered Metamorphic Fillers as Soft Stone Fillers

摘要

In order to discuss on highly weathered metamorphic fillers as soft stone fillers, firstly the CBR tests for analysis on viability as embankment filler are conducted on three different highly weathered metamorphic fillers. Secondly the rock strength tests and particle broken tests are processed to study on how weathered degree and rock structure have an effect on them. Based on the above conclusions, evaluation criteria are proposed that have certain guidance and reference on mountainous highway construction.
