AASHTO #57 Stone Specs

AASHTO #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.

Gradation of Coarse Aggregate by Sieve Analysis

Aggregate gradation is defined as the particle size distribution of both the stone and sand present in the concrete matrix. This property of aggregate has been heavily undergoing research for over a century but the effects of which on concrete properties is still somehow misunderstood.

the properties of both the fresh and hardened concrete. Unsatisfactory gradation may lead to: 1. Segregation of the mortar from the coarse aggregates. 2. Bleeding of water below and around larger aggregates and on the surface of the concrete. 3. Settling of aggregates, leaving paste in the top layer of the concrete.
