Embodiment 1
[0025] To determine the density of an asphalt core sample:
[0026] (1) Use an electronic scale of model JD2000-2 (the maximum weighing capacity is 2000g, and the sensitivity is 0.01g), and weigh the air mass of the dry test piece m a =508.37g;
[0027] (2) Fully mix the two components of liquid silicone rubber evenly, apply the mixed liquid silicone rubber evenly on the surface of the dry test piece with a spatula, completely seal the surface of the test piece, and then place the test piece at room temperature for 30 minutes , to obtain a sealed specimen after solidification;
[0028] (3) Weigh the air mass m of the sealed test piece s =527.49g;
[0029] (4) Hang up the net basket, immerse in the overflow water tank, adjust the water level, level or reset the balance; then put the sealed test piece into the net basket and immerse it in water, and read the mass m in the water after the reading is stable. c =288.19g;
[0030] If other tests need to be done on the test piec...
Embodiment 2
[0036] Determination of the density of a large cuboid asphalt mixture:
[0037] (1) Use an electronic scale of model JA51001 (the maximum weighing capacity is 5100g, and the sensitivity is 0.1g), and weigh the air mass of the dry test piece m a =2922.7g;
[0038] (2) Fully mix the two components of liquid silicone rubber evenly, apply the mixed liquid silicone rubber evenly on the surface of the dry test piece with a spatula, completely seal the surface of the test piece, and then place the test piece at room temperature for 30 minutes , to obtain a sealed specimen after solidification;
[0039] (3) Weigh the air mass m of the sealed test piece s =2978.6g;
[0040] (4) Hang up the net basket, immerse in the overflow water tank, adjust the water level, level or reset the balance; then put the sealed test piece into the net basket and immerse it in water, and read the mass m in the water after the reading is stable. c =1663.4g;
[0041] If other tests need to be done on the...
