Asphalt Mixture Closed Triaxial Tester Apparatus and Materials:

Closed triaxial pressure gauge.

The main body is a pressure chamber, which is composed of a plexiglass cylinder (inner cylinder) with an inner diameter of 140mm and a height of 260mm, and a pair of flanged steel flanges at each end of the device and the cylinder. The latex film is sleeved on the upper and lower flange seats and compressed with a rubber pad. The latex film divides the pressure chamber into an inner cavity and an outer cavity. The inner cavity is used to place the test piece, and the outer cavity (that is, between the latex film and the inner wall of the plexiglass tube) is connected to the super constant temperature water tank through a water inlet valve and a water outlet valve with a precision pressure gauge. There is a heat insulation chamber on the periphery of the cylinder, and it is connected to the super constant temperature water tank through another group of water inlet switch and water outlet switch.

Tight pressure gauge: 1.6MPa range, 0.01MPa division.

Hollow indenter: 175mm high, 100mm diameter of bottom bearing surface.

Super constant temperature water tank: can keep 60 ℃ ± 0.5 ℃, there are two pairs of water inlet and outlet pipes.

Press: 100kN.

Dial indicator and dial stand.

Oven: Equipped with temperature regulator.

Latex sleeve: 100mm in diameter and 400mm in length.

Note: The latex film must be a non-breathable latex sleeve without aging or adhesion.

Air extractor or vacuum pump.

Others: thermometer, stopwatch, balance, filter paper, talcum powder, etc.
