The AZA0956 Ductility Testing Apparatus from AZALAB is a precision-engineered laboratory instrument designed to determine the ductility of bituminous materials, including paving grade bitumen, asphalt binders, and similar viscoelastic materials. Ductility is defined as the ability of a bituminous material to undergo tensile deformation before rupture and is a critical parameter for evaluating binder performance in flexible pavements.

In road construction, ductility testing plays a vital role in assessing how well bitumen will perform under temperature variations, repeated traffic loading, and long-term aging. A binder with adequate ductility is less prone to cracking and brittle failure, thereby contributing to durable, flexible, and high-performing pavements. The AZA0956 accurately measures the elongation distance (in centimeters) that a standard bitumen specimen can be stretched at a specified temperature and rate of pull before breaking.

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.

The AZA0940 Semi-Automatic Penetrometer from Azalab is a high-precision laboratory instrument designed for the accurate determination of the consistency of bituminous materials, including bitumen, asphalt, and other semi-solid products such as greases and waxes. Engineered to bridge the gap between manual and fully digital systems, the AZA0940 combines robust mechanical construction with digital timing and automated needle release, delivering excellent accuracy, repeatability, and ease of operation.

This instrument is widely used in civil engineering laboratories, highway authorities, asphalt plants, research institutions, and quality control laboratories, where dependable penetration testing in compliance with ASTM D5, EN 1426, and AASHTO T49 is required.
