# RESIDUE OF BITUMEN EMULSION ON 600 MICRON SIEVE (IS-8887-2004)

## Purpose

This test is done by sieving through a 600 micron sieve for the determination of residues of bituminous emulsions.

## Device

• 600 micron sieve A circular sieve of about 100 mm in diameter and 40 mm in height.
• metal or glass dish – A small metal or glass vessel (such as a watch glass) of about 110 mm in diameter.
• Oven – A well ventilated oven thermostatically controlled from 100 to 110″C.
• Remanent – A capacity 250g and accuracy 0.01g and a capacity 10kg and accuracy 1g.
• Pot – A clean, weighed, 1.5-liter container.

## Process

1. Wash the 600 µm IS sieve with xylene and then with acetone. Place it in the dish, in the oven at 100 . dry on0C to 1100C for one hour, refrigerate and, with dish, weigh down to the nearest 0.01 g (W.)1,
2. Remove the sieve from the sieve and moisten with the solution. Remove the 4-liter sample by stirring it slowly and immediately strain it through a sieve into a clean, dry-weight container (W.)4,
3. room temperature and 50 . Filter the emulsion at low and high viscosity0c respectively. When the entire emulsion is drained through the sieve, remove the sieve and weigh the container to the nearest 1 g (W.)2,
4. Wash the strainer repeatedly with distilled water until the wash runs clear. Put the sieve in a small pot in the oven for two hours at 105±5. keep to dry0C. Cool and weigh together to the nearest 0.01 g (W.)3,

Calculate the residuals as follows:

Residue, Percentage Retained = (W.)3 – woo1) / (w2 – woo4) x 100

Where

woo1 = mass of sieve and small vessel in g

woo2 = mass in g of container and emulsion

woo3 = mass of the strainer, small plate and residue in g; And

woo4 = mass of container in g

Take the average of the three values ​​obtained for the residuals, percentage.

## requirement criteria
