  • Self-Compacting 3/4" stone JLC-Online Forums

    May 21, 2020· The crushed rock I was referring to, is, in my area, like a red quartzite, and it is still sorted and washed according to size and to remove fines. The larger the rock, the more reservoir capacity as far as drainage, because of more opens in the aggregate. 3/8 pea rock is the product of choice around here for AWWF footings, and 50% backfill.

  • Influence of Lateral Loading on Compaction Characteristics

    Crushed waste rock can be used as backfill in goafs to allow re-use of otherwise solid waste and to control surface subsidence. If a certain lateral stress is applied to crushed waste rocks beforehand, they are densified. Therefore, this research investigated the effects of lateral stress on compaction characteristics of waste rocks for backfilling by utilising a self-designed bidirectional
