Characterization/measurement of 密度 and voids are important properties for a complete analysis of the proposed mix design. 正如上面所提到的, specific gravity and 密度 values are determined using the ASTM D2041/AASHTO T 209 theoretical method (Rice test) for the loose asphalt material and ASTM D2726/AASHTO T 166 to determine the bulk specific gravity of compacted specimens. T在这里 is also a need to describe various types of air void contents. Air void content in compacted mixtures consists of the small spaces between coated aggregate particles in a compacted mixture and is a test method defined in ASTM D3203/ AASHTO T 269. T在这里 are two other void values determined by calculations.

• Voids in mineral aggregates (影响规律) are defined as the void space between the aggregate particles in a compacted mixture. 影响规律 is calculated based on the aggregate bulk specific gravity and is expressed as a percentage of the bulk volume of the compacted mixture.

的 formula for calculating 影响规律 is:

$影响规律 = {100 - {GmbPs \over ’}}$

= 散装 specific gravity of the aggregate
Gmb = 散装 specific gravity of compacted mix
Ps = Aggregate, percent by total weight of mix

• Voids filled with asphalt (的浓度) in a compacted paving mixture, consisting of that portion of the initial voids in the aggregate (影响规律) which have been filled with the non-absorbed asphalt.

的浓度 can be determined by the following equation:

$的浓度 = {100({影响规律 - Pa \over 影响规律})}$

Pa = air voids in compacted mixture, percent of total volume
