AUTOMATIC COMPACTOR FOR BITUMINOUS MIXES AZA0963

The AZA0963 Automatic Compactor for Bituminous Mixes from AZALAB is a precision-engineered laboratory instrument designed for the controlled and repeatable compaction of asphalt mixture specimens in accordance with the Marshall Mix Design method. It is an essential piece of equipment for civil engineering laboratories, highway authorities, asphalt producers, and research institutions involved in asphalt pavement design, evaluation, and quality control.

By accurately simulating the compaction energy imparted by traffic loads, the AZA0963 ensures that laboratory-prepared specimens closely represent field-compacted asphalt layers. This results in highly reliable data for determining Marshall Stability, Flow values, density, air voids, VMA, and optimum bitumen content, which are critical parameters for designing durable and long-lasting flexible pavements.

Description

Working Principle

The AZA0963 operates on a fully automated Marshall compaction mechanism. A motor-driven hammer weighing 4.536 kg (10 lbs) is repeatedly lifted and dropped from a fixed height of 457.2 mm (18 inches) onto the asphalt specimen contained within a standard Marshall mould.

The machine is equipped with a digital programmable blow counter, allowing the operator to pre-set the required number of blows (commonly 50 or 75 blows per face, as per design requirements). Once the programmed number of blows is completed, the compactor automatically stops, ensuring strict adherence to standard procedures and eliminating operator dependency.

An automatic mould rotation system ensures uniform distribution of compaction energy across the specimen surface, resulting in consistent density and improved repeatability of test results.


Key Features & Advantages

  • Fully Automated Operation
    Eliminates manual hammering, reducing operator fatigue and test variability.

  • High Precision Compaction Energy
    Fixed hammer weight and drop height ensure consistent and repeatable specimen preparation.

  • Digital Blow Counter with Auto Shut-Off
    Guarantees exact compliance with specified compaction requirements.

  • Uniform Compaction
    Automatic mould rotation ensures even distribution of blows across the specimen.

  • Heavy-Duty Construction
    Rigid steel frame minimizes vibration and ensures long-term durability in demanding lab environments.

  • Enhanced Laboratory Efficiency & Safety
    Improves productivity while reducing physical strain on technicians.
