  • Effect of Aggregates on the Properties of Concrete

    It is based on the percentage voids in the aggregate after compaction as per IS 2386-1963 part-1. This test gives a value called as angularity number. The percentage voids are calculated as follows: Thus rougher the surface as that of a crushed stone, better the bond. Secondly bond is also affected by other physical and chemical properties

    containing only about 2 percent plus No. 4 aggregate, the highest densities were ob­ tained with the heavy pneumatic-tired roller. In 1961 the field experiments were con­ tinued on three additional projects. Because all materials in the 1961 experiments were graded crushed stone, it was decided that only the vibrating roller would be used.

  • AASHTO #57 Stone Specs Capitol Flexi-Pave

    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.

  • How much volume is lost after compacting 3/4" crushed stone?

    The loose drop weight of a relatively uniform (all the rocks are similar size and shape) 3/4" stone will be about 80-90% depending on the stone (angularity and phi). Presuming that you are compacting to 100% of some form of "proctor density", because you're awesome at compacting and have a monster machine (and thin lifts), that's 100/80=125%.
