Density is calculated using the G mc of the core and the G mm of the mix. The PF density for each lot is calculated using the density test results of all of the sublots. Cores that are cut in half, as required by Standard Specification Section 403.15.4, will double the number of test results used to determine PFdensity.
Density testing will be performed on the first core taken. Asphalt content and aggregate gradation testing will be performed on a single sample prepared by combining asphalt concrete from the three cores obtained. If the acceptance test results are appealed, the asphalt content and aggregate
