KN-3289 Density Of Asphalt Materials

Overview

  The apparatus consists of the following items, it covers the determination of the density of semi-solid and solid bituminous materials by weighing in air and in water

1 Crucible, nickel, high-form, 30-mL capacity, about 43 mm in height by 41 mm in diameter.

2 Bath, constant-temperature, capable of maintaining the test temperature within 60.1°C.

3 Thermometer, calibrated liquid in glass, total immersion-type, of suitable range with graduations at least every 0.1°C and a maximum scale error 0.1°C . Thermometers commonly used are 63C. Any other thermometer device of equal accuracy may be used.

4 Balance, capable of weighing to 0.001 g. It shall be fitted with a pan straddle and a wire basket

5 Basket and Pan Straddle, capable of holding the crucible in air or in water by suspending from the balance beam. The basket may be made out of soft 0.81-mm copper wire or equivalent. The straddle may be made out of about 0.81-mm aluminum sheeting formed to provide support of the beaker while permitting free movement of the pan
