Research on Design Indicators for Graded Crushed

Therefore, based on the modified vibration compaction, the guidelines for standardized mix design of graded crushed stone mixture in Fujian province are proposed: the resilient modulus of 300 MPa and the deformation rate of 10 –8 in the dynamic triaxial test are used as the performance indicators of the bearing capacity and the Get price

AASHTO #57 Stone Specs

2018-3-7AASHTO #57 Stone Specs AASHTO #57 stone as defined by quarries, state agencies, etc. is an open-graded, self-compacting aggregate blend of size 5, 6, 7 stone. This material cannot be 'compacted' in a true sense, but can be properly oriented with compaction equipment. This is particularly important when using #57 stone under Flexi-Pave surfaces.Get price
