However, since the aggregate is made up of particles, it is reasonable that the compacted density of the aggregate is between (150-180 lb/ft^3). If you consider an entire road bed compacted at 95%, would it be reasonable to estimate that the density of the aggregate road bed is 165 (lb/ft^3) as stated in the CERM under aggregate properties section?
