scope of application:

The test method of using combustion method to determine the asphalt content in asphalt mixture is used to evaluate the construction quality of asphalt pavement. It meets the requirements of JJG (Traffic) 072-2024 "Calibration procedure of combustion method asphalt content tester".

technical parameter:

1、Sample capacity: 1000g~4500g;

2、Weighing device: range 10kg or 12kg scale value: 0.01g;

3、main chamber

Working temperature: (538±5) ℃ or (482±5) ℃;

Temperature uniformity: less than or equal to 5℃;

Temperature fluctuation: ±5℃:

Heating time: the time from room temperature to 538℃ is less than or equal to 25min.

4、Secondary combustion chamber

Working temperature:(900±10)℃;

Heating time: the time from room temperature to 900℃ is less than or equal to 25min.

5、Weighing system

Indication error: the maximum allowable error is ±0.10g;

Repeatability: not greater than 0.10g;

Unbalance: not greater than ±0.10g.

6、Timing system: the value is (180±10) s;

7、Combustion chamber door lock: Equipped with interlocking locking mechanisms and pull rings, this design enables the door to be tightened or released, enhancing its sealing performance and preventing smoke from escaping, which could otherwise cause environmental pollution. Additionally, the electric cylinder allows for adjusting the tension of the door and combustion chamber, improving the door's flexibility. This feature enables automatic door closing, reducing the vibration impact on the balance caused by manual operation.
