you asked, “are compaction tests of #610 crushed stone reliable?” the answer is yes. if a proctor, either d698 or d1557, can be performed on the material then in-place density tests can be performed on it. my recollection of the gradation for #610 stone is.construction - how much volume is lost after compacting 3/4' crushed stone…,if you are compacting road crush with a vibratory plate you will get about 10 to 15% compaction. (this is based on you having a stable compacted base first. if you are putting the road crush on top of top soil you will lose more to compaction.) if you use a jumping jack, about 20% would be accurate..the bearing and breakage characteristics of crushed stone …,the compaction test system of crushed stone aggregate (figure 2) includes a home-made compaction device, a loading system, and a data acquisition system. the compaction device is composed of a hollow piston, a cylinder tube, a bottom plate, and other components..specifications for crushed aggregate base coarse #2 & #3 (compaction …,crushed aggregate base coarse (compaction gravel) shall consist of one or more courses or layers of coarse aggregate, either crushed gravel or crushed stone, fine aggregate and binder or filler blended as necessary to produce an intimate mixture of the
the specimens of mcg-a were prepared by compaction using 4.5ec at w = around 4%, slightly lower than wot =6.1%. at w = around 4%, the strength and stiffness exhibit respective maximum values ( fig. 8 a and b), therefore, the strength and stiffness of mcg-a are not under-estimated when compared with those of repa19..granular sub-base base (gsb) quantity / compaction factor …,volume of gsb layer = ( length of gsb bed x width of gsb bed x thickness of gsb layer) volume of gsb layer = l x b x t. volume of gsb layer = 500 x 7 x 0.150 volume of gsb layer = 525 cubic metre. we know that. mass = volume x density. in this case -. mass = volume x mdd. putting the value in the formula..compaction and breakage characteristics of crushed stone used …,crushed stone is a commonly used aggregate for backfill material in engineering, and its compaction behavior under load needs to be well understood. in this work, a series of compaction tests were carried out on the same batch of crushed stone samples with the same gradation..research on design indicators for graded crushed stone mixture …,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
