STANDARD PENETROMETER AZA0938

Description

Role of AZA0938 in Bitumen Consistency Testing

Penetration testing is one of the most fundamental tests in bitumen characterization. The AZA0938 measures the depth of penetration of a standard needle into a bitumen sample under:

• A specified load (typically 100 g)

• A fixed time period (normally 5 seconds)

• A controlled temperature (commonly 25°C)

The penetration depth is expressed in tenths of a millimeter (0.1 mm) and provides a direct indication of the binder’s hardness or softness:

• Higher penetration values indicate softer binders, suitable for colder climates

• Lower penetration values indicate harder binders, suitable for hotter climates

Accurate penetration results are critical for pavement design, material selection, and long-term performance evaluation.

Robust Mechanical Design for Consistent Results

The AZA0938 is engineered with a classic mechanical architecture, ensuring durability and long service life in demanding laboratory environments.

• Heavy-duty cast iron base ensures excellent stability and vibration-free operation

• Rigid vertical columns provide precise vertical alignment of the plunger

• Rack and pinion fine adjustment mechanism allows accurate positioning of the needle tip on the sample surface

• Manual needle release and locking system ensures controlled penetration during the test interval

The instrument is designed for experienced laboratory operators who require direct control and repeatable results.

Frequently Asked Questions (FAQ)

Q1: What is the primary use of AZA0938?
It measures the consistency (hardness or softness) of bituminous materials through penetration testing.

Q2: Is a stopwatch required?
Yes. As a manual penetrometer, an external stopwatch is required to control the 5-second penetration period.

Q3: How does AZA0938 differ from digital models?
AZA0938 requires manual control and visual reading, whereas digital models automate timing and measurement.

Q4: What industries use this instrument?
Primarily road construction, civil engineering, petroleum testing, and academic research.
