So this aggregate was not strong. 4 CONCLUSION. The ACV value is more than 45% for aggregate used for concrete for non- wearing surface and less than 25% for wearing surface like runways and roadways. The higher the aggregate crushing value, the lower the resistance to crushing under the gradually applied compressive load. 5 REFERENCES
