ASPHALT CONTENT TESTER AZA0967
The AZA0967 Asphalt Content Tester from AZALAB is an advanced laboratory instrument engineered for the rapid, accurate, and environmentally responsible determination of asphalt (bitumen) content in Hot Mix Asphalt (HMA) and other asphalt paving mixtures. The system operates on the Ignition Method (Loss on Ignition), representing a significant technological improvement over conventional solvent extraction techniques.
By eliminating hazardous solvents and utilizing controlled high-temperature combustion, the AZA0967 ensures fast turnaround, high repeatability, improved laboratory safety, and regulatory compliance, making it an essential tool for modern road construction quality control laboratories.
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:
-
The asphalt mixture sample is placed in a perforated stainless steel basket.
-
The basket is introduced into a high-temperature electric furnace.
-
The furnace heats the sample to a controlled temperature (typically 538°C or 650°C, depending on aggregate type).
-
The asphalt binder combusts completely, leaving only the aggregate.
-
An integrated high-precision balance continuously measures weight loss.
-
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.
Standards Compliance
The AZA0967 is designed to meet or exceed internationally recognized testing standards, ensuring universal acceptance:
