crushed limestone is an angular rock, typically produced by mining and crushing suitable rock deposits into desired sizes. it is one of the most accessible natural resources and a major basic raw material used by construction, agriculture and other industries. it differs from gravel in that the latter has round edges and is formed through natural weatherization and erosion.

in current chinese technical specification, the crushing value of the coarse aggregate for surface layer of asphalt pavement is no greater than 26% . so, the crushing value standard of basalt coarse aggregate used in pa mixture should be increased to not more than 26%/1.48 = 17.6%.
strength properties of rocks and rock masses 1. introduction 2. testing of intact rock for strength in general, it has been found that the value of the load p at failure depends largely on the core diameter. hence, the results of point load tests avoid crushing that could throw doubts as to the mechanism of failure in the test sample
aggregate crushing value civil engineering. aggregate crushing value this test helps to determine the aggregate crushing value of coarse aggregates as per is: 2386 (part iv) – 1963. the apparatus used is cylindrical measure and plunger, compression testing machine, is sieves of sizes – 12.5mm, 10mm and 2.36mm
for example, if it is calculated that one trainload if rock will be de live red to the plant each one half hour, on the average, and our primary crusher has been chosen with a view to getting this tram through in ten minutes, then we must, enviously. either provide stage crushing to match the high capacity of the primary or, if we want to get the most work out of our investment dollar, set up
