ASPHALT CONTENT TESTER AZA0967

Description

Principle of Operation

The AZA0967 determines asphalt binder content by burning off the bituminous material from a prepared asphalt mixture sample under controlled conditions.

Operating Process:

1. The asphalt mixture sample is placed in a perforated stainless steel basket.

2. The basket is introduced into a high-temperature electric furnace.

3. The furnace heats the sample to a controlled temperature (typically 538°C or 650°C, depending on aggregate type).

4. The asphalt binder combusts completely, leaving only the aggregate.

5. An integrated high-precision balance continuously measures weight loss.

6. Once mass stabilization is achieved, the system automatically calculates the asphalt content based on pre- and post-ignition weights.

This automated cycle provides rapid, accurate, and repeatable results, significantly reducing testing time compared to solvent extraction methods.
