Density Of Asphalt Materials
Density Of Asphalt Materials TT-3289
Density Of Asphalt Materials TT-3289 comprises the following items, covering the determination of the density of semi-solid and solid bituminous materials through weighing in air and in water.
1. Crucible: Nickel, high-form, with a capacity of 30 mL, approximately 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, with a suitable range and graduations at least every 0.1°C, with a maximum scale error of 0.1°C. Commonly used thermometers include the 63C model. Alternatively, any other thermometer device of equal accuracy may be used.
4. Balance: Capable of weighing to 0.001 g. It shall be equipped 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 it from the balance beam. The basket may be constructed of soft 0.81-mm copper wire or equivalent material. The straddle may be made from approximately 0.81-mm aluminum sheeting formed to provide support for the crucible while allowing free movement of the pan.
