For the purpose of demonstrating the 0.45 Power Curve Void Prediction Method, approximated values of the measured bulk density – and subsequently, percent voids – will be used. Table A.1 represents the voids in dry-rodded aggregate in omitted sieve sizes and the voids in combined with a gradation lying exactly on the maximum density line. This example assumes that aggregate larger than the #4 sieve has a negligible effect on bulk density for simplicity.
