1Quality Test for every 40 tonnes/200 drums or fraction thereof

10 What is the required size of an Emulsified Asphalt sample for quality test?

4 liters

11 A Slow-Curing Cutback Asphalt is readily identified by the characteristic smell of?

Oil

12 This test indicates the safe heating temperature of the asphalt.

Flash Point

13 This test measures the ability of asphalt to stretch without breaking.

Ductility

14 In Ductility Test of asphaltic materials (ASTM D113), the specimen in the briquette is pulled apart at a rate of?

5 cm/min

15 This test determines if the asphalt is overheated or not during production.

Spot Test

Specific Gravity

17 A laboratory personnel uses a pycnometer with a mass of 52.135 g for determining the specific gravity of an AC 60- 70 Grade Asphalt Cement sample. After filling it up with distilled water, the resulting weight is 62.904g. The personnel then added 4.667 g sample to the pycnometer to make it filled with sample. An additional 6.196 g of distilled water is required to make the pycnometer half-filled with sample to make it full. Determine the sample's specific gravity.

1.021
