Question

The following data was obtained on a sample of a bituminous material mass in air 1200g mass in water 680g specific gravity of coarse aggregate 2.68 specific gravity of fine aggregate 2.74 specific gravity of the filler 3.1 specific gravity of bitumen 1.02 binder content by mass 6.4% coarse aggregate content by mass 60% filler content by mass 10%

calculate void content ,binder content by mass, voids in mineral aggregates and the % voids filled with binder

Answer 1

To calculate void content, binder content, voids in mineral aggregates, and the percentage of voids filled with binder, specific calculations need to be performed based on the given data.

Step-by-step explanation:

To calculate the void content, we need to first calculate the bulk density and then subtract it from the particle density. The bulk density can be calculated by dividing the mass of the aggregate by its volume. The particle density can be calculated by dividing the mass of the aggregate by its volume excluding the voids.

The binder content by mass can be calculated by multiplying the mass of the bitumen by the binder content percentage.

The voids in mineral aggregates can be calculated by subtracting the bulk density of the aggregate from the apparent density of the aggregate.

The percentage of voids filled with binder can be calculated by dividing the binder content by the total voids and multiplying by 100.
