ASTM D4469-11
(Test Method)Standard Practice for Calculating Percent Asphalt Absorption by the Aggregate in an Asphalt Pavement Mixture
Standard Practice for Calculating Percent Asphalt Absorption by the Aggregate in an Asphalt Pavement Mixture
SIGNIFICANCE AND USE
The amount of asphalt absorbed by the aggregate contributes little or nothing to the durability of an asphalt pavement in service other than possibly providing greater resistance to stripping in the presence of water.
Percent asphalt absorption can be an indicator of changes that may occur in plant mix production during construction.
The calculated percent asphalt absorption can be used for calculating percent air voids during paving mixture design.
SCOPE
1.1 This practice covers equations for calculating percent asphalt absorption by the aggregate in an asphalt paving mixture, expressed as percent of the oven-dry mass of the aggregate in the paving mixture. This calculation is based on measured values for components and properties of an oven-dry asphalt paving mixture.
This practice does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Summary of Test Method
3.1 The percent asphalt absorption for an oven-dry paving mixture (expressed as percent of the oven-dry mass of the total
aggregate in the paving mixture) can be calculated by means of equations in which measured values for the theoretical maximum
specific gravity of an oven-dry paving mixture, its asphalt content (expressed either as percent of the total mass of a sample of
oven-dry paving mixture, or as percent of the mass of oven-dry aggregate in a sample of oven-dry paving mixture), the apparent
specific gravity of the asphalt and the weighted averageASTM bulk specific gravity of the oven-dry total aggregate in the paving
mixture (Note 1), has been substituted. ).
NOTE 1—Whenever it is referred to in this practice, the phrase, “weighted averageASTM oven-dry bulk specific gravity of the aggregate,” refers to
