Mix Volumetrics — Core % Compaction
Core % Compaction calculation for asphalt mix design and QC.
92% of Gmm is the cliff edge: below it, air voids interconnect and the pavement drinks water — studies hang a year of service life on every percent of density near the line. Pay factors are written around this physics; so are the bonus clauses good crews chase.
Formula
Note: Paving estimates only — the project mix design, agency specification and the plant's QC data govern. Temperature models are simplified; verify with an infrared gun and density gauge on the mat.
