Product Details

2025 Asphalt Emulsified Asphalt Emulsification Speed Test Blender

According to the industry standards of the People's Republic of China:JTG3410-2025In the "Test Regulations for Asphalt and Asphalt Mixtures in Highway Engineering"T 0658—2025Emulsified AsphaltDemulsification performanceTest. At the same time, the product also conforms to the national standards and the relevant standards of the petrochemical industry. The electric emulsified asphalt and mineral aggregate mixing tester is applicable to the mineral aggregate and lotion with the specified gradation25℃±1When mixing at ℃, check the state and uniformity of lotion and mineral aggregate when mixing.

1、 Emulsified asphalt emulsion breaking speed test mixer product structure:

Emulsified asphalt emulsion breaking speed test mixer is powered by an electric motorContinuous feeding systemComposed of a stirring blade, the motor drives the stirring blade to rotate, enabling the material to achieve mixing and mass transfer (dissolution, extraction, absorption).

4Cationic emulsified asphalt emulsion breaking test

1Weigh out250g±5gTransfer emulsified asphalt into a sample bottle, keep it at a constant temperature, and then take it100g±1gEmulsified asphalt is transferred into a weighed mixing container.

2Start the mixer to260r/minStir at a certain speed while starting the feeder and timer. As the filler continues to be added, the mixture thickens. When the mixture turns into a paste, agglomerates, and does not adhere to the mixing tank, or when a large amount falls off from the mixing tank wall, it is considered that the emulsified asphalt has broken the emulsion. Stop feeding the filler and timed to stop mixing, and record the feeding time.

3As the standard filler continuously falls on the mixing tank or a large amount falls off from the mixing tank wall, the emulsifier material and timer are considered to be timed, and then the motor is stopped to record the feeding time t₂Weigh the total mass of the mixing tank and mixer containing the mixture, and record it asm₂. Adoptingm₂ andt_aCheck the feeding speed of the feeder and adjust it if necessary. According to the above methods and steps, take another sample for parallel testing.

4、According to the formula(T 0658-1)Calculate the demulsification index of emulsified asphalt, accurate to0.1.

4Where:

M₁ ——The total mass of the mixing tank and mixer,g；

M_e ——The quality of emulsified asphalt,g；

M₂——The total mass of the mixing tank and mixer containing the mixture,g；

k ——The demulsification index constant of standard filler samples.

Calculate the arithmetic mean of the measured values of the demulsification index of two samples as the test result of the demulsification index of the samples, accurate to1A unit.

5allowable error

The relative allowable error for the repeatability test of demulsification index is10%.

The relative allowable error for the reproducibility test of demulsification index is40%.
