What it is
Aggregate and mixture density information is combined using the specified method calculation.
Public test guide
Binder absorption
Estimates the amount of binder absorbed into aggregate pores rather than remaining as effective coating.
Plain-language explanation
What the test tells you.
The project specification controls the exact method and acceptance requirement.
What is used
Representative materials and the required aggregate, binder and mixture density results.
What it determines
Absorbed binder and/or effective binder content for the mixture.
Why it matters
Improves mix-design interpretation because absorbed binder does not contribute fully to the effective film around particles.
Typical test sequence
From sample
to result.
- 01
Obtain the required constituent and mixture properties
- 02
Apply the specified density relationships
- 03
Calculate absorbed and effective binder quantities
