Asphalt Density Calculator
This calculator determines the density of asphalt using core sample weights measured in water and air. It’s used in road construction quality control to assess compaction levels and ensure material performance.
Calculate Asphalt Core Sample Density
Asphalt Density Formula
Where:
- $$W_1$$ = weight of basket in air
- $$W_2$$ = weight of sample + basket in air
- $$W_3$$ = weight of basket in water
- $$W_4$$ = weight of sample + basket in water
This method calculates asphalt density by Archimedes’ principle, using displaced water volume.
Asphalt density is a critical parameter in pavement design and construction. It reflects how well the material has been compacted and its ability to bear loads. This formula is based on the difference between dry and submerged weights of a core sample, allowing accurate field or lab analysis using water displacement techniques.
