Automatic Marshall Compactor

Automatic Marshall Compactor – Bituminous Mix Testing Machine

The Automatic Marshall Compactor is a precision-engineered instrument designed to simplify and standardize the compaction of bituminous samples as per the Marshall Mix Design Method. Ideal for quality control labs and civil engineering research, this apparatus ensures consistent, repeatable compaction cycles to prepare asphalt specimens for stability and flow testing.

Equipped with a programmable digital display counter, it automatically stops once the preset number of blows is achieved. The compactor features a sliding weight hammer, precision-aligned mold guide, and automatic trip mechanism, all housed in a sturdy, lab-safe frame.

Key Features of the Automatic Marshall Compactor

Fully Automatic Operation: Automatically performs compaction and stops once the desired number of blows is reached.

Consistent Impact Energy: The sliding hammer delivers repetitive, uniform blows from a set height (457 mm) for consistent compaction.

Digital Control Panel: Easy-to-use interface to preset the number of blows, ensuring repeatability.

Accurate Mold Alignment: Mold holder and guide maintain proper vertical alignment for accurate compaction.

Built-in Safety & Auto Cut-Off: Automatically switches off after completing the compaction cycle for safety and efficiency.

Durable Design: Heavy-duty construction ensures long-term reliability in demanding lab environments.

Applications of the Automatic Marshall Compactor

Marshall Mix Design: An Essential tool for preparing samples to evaluate stability, flow, and optimum bitumen content.

Asphalt Mix Testing: Helps determine the load-bearing capacity and durability of asphalt pavements.

Educational Demonstration: Commonly used in universities and training centers for teaching pavement engineering and compaction techniques.

Construction Quality Control: Supports routine compaction testing in bitumen labs and material testing centers.
