Asphalt bulk relative density and voids content

Measures specimen density and calculates the air spaces remaining in compacted asphalt.

Plain-language explanation

What the test tells you.

The project specification controls the exact method and acceptance requirement.

A compacted specimen is weighed under the specified dry, saturated or sealed conditions and compared with maximum theoretical density.

Compacted specimen, balance, water bath or sealing setup, dimensional tools and maximum theoretical density result.

Bulk relative density and calculated air-voids content.

Helps assess compaction and mix structure, both of which strongly influence pavement durability and performance.
