FILTERLESS CENTIFUGE EXTRACTOR AZA0947
The AZA0947 Filterless Centrifuge Extractor from AZALAB is a high-efficiency laboratory instrument engineered for the rapid and accurate determination of bitumen (asphalt) content in hot-mixed bituminous paving mixtures. Unlike conventional centrifuge extractors, the AZA0947 eliminates the need for disposable filter papers, thereby simplifying operation, reducing consumable costs, and minimizing handling-related errors.
This makes the AZA0947 particularly suitable for high-throughput quality control laboratories involved in road construction and pavement evaluation, especially within large-scale infrastructure projects.

FRAASS BREAKING POINT APPARATUS AZA0935
The AZA0935 Fraass Breaking Point Apparatus from Azalab is a specialized laboratory instrument designed for the accurate determination of the Fraass Breaking Point of bitumen and bituminous binders. This test is essential for evaluating the low-temperature behavior and brittleness of asphalt materials, particularly for pavements exposed to cold climatic conditions.
The Fraass Breaking Point represents the temperature at which a thin film of bitumen loses flexibility and cracks when subjected to controlled cooling and repeated flexing. Determining this temperature is critical for selecting suitable binder grades and preventing thermal cracking in asphalt pavements, thereby ensuring long-term durability and serviceability.
MIXER WITH HEATING JACKET AZA0955
The AZA0955 Mixer with Heating Jacket from AZALAB is a specialized laboratory apparatus engineered for the precise, uniform, and temperature-controlled mixing of materials that require elevated temperatures during blending. It is an essential instrument in civil engineering and highway material laboratories, particularly for the preparation of bituminous and asphalt mixes such as Hot Mix Asphalt (HMA).
By maintaining materials at a controlled and uniform temperature throughout the mixing process, the AZA0955 ensures optimal binder viscosity, thorough aggregate coating, and homogeneous sample preparation. This level of control is critical for producing accurate, repeatable, and representative laboratory specimens, which directly influence the reliability of asphalt mix design, quality control, and performance testing.
REFRIGERATED DUCTILITY TEST AZA0957
The AZA0957 Refrigerated Ductility Testing Apparatus from AZALAB is a specialized laboratory instrument designed to determine the ductility of asphalt binders and bituminous materials at low temperatures. This test is critically important for evaluating the performance of asphalt pavements in cold and variable climatic conditions, where thermal contraction can lead to cracking and premature pavement failure.
Ductility, defined as the distance a bituminous binder can be stretched under tensile stress before rupture, is a key indicator of binder flexibility. At low temperatures, asphalt binders become increasingly stiff and brittle. The AZA0957 enables engineers and material technologists to accurately assess a binder’s resistance to thermal cracking, ensuring the selection of materials suitable for cold climates and long-term pavement durability.
