Research on Compaction Characteristics and Particle Breakage of Soil-aggregate Mixture

Based on a certain big site preparation project, the method to determine the dry density of filling for soil-aggregate mixture has been studied, and the characteristics of particle breakage after vibrating is discussed. The research results show that the surface vibration compaction method to determine the maximum dry density with mixture is suitable to soil-aggregate mixture. Considering the compaction factor of 0.94, the dry density control standard deducing from the maximum dry density is close to the projected field compaction test results. The particle breakage of soil-aggregate mixture during vibration is close to 20%, which shows that the particle breakage is significant. This study may have a certain significance to similar projects.
