Get PriceJan 15, 2019The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm3. Therefore, these numbers translate directly to g/cm3, or tonnes per cubic meter (t/m3).

So when you're saying 1/2 HMA people generally know what that means. Where you might see a problem is in drawing the maximum density line to help with designing a mix's gradation. The maximum density gradation line represents
Get PriceCoarse aggregates are classified into two main groups (i) single-size aggregate and (ii) graded aggregate. Single-size aggregate is based on a nominal size specification. It contains about 85 to 100 percent of the material which passes through that specified size of the sieve and zero to 25% of which is retained in the next lower sieve.
