1992-9-1 A new approach to the topic of numerical description of void characteristics of noncohesive soils and similar granular materials is presented. Based upon a simple stochastic model of the void structure and void sizes, theoretical equations are derived by means of which the void ratio of a soil can be calculated from its grain‐size distribution.

2013-12-1 Relatively low ρ d values of REPA19 are due partly to a lower specific gravity, G s, by the inclusion of mortar (having a lower G s), but mainly to a higher void ratio (shown later in Fig. 13). It may be seen from Fig. 6 that the particles of REPA19 were crushed to some extent by compaction, slightly more than MCG-A, due likely to highly ...

2018-3-7 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.
