Working Principle

A cylindrical bitumen specimen is placed in a breaking head and subjected to a gradually increasing load. The apparatus records the maximum load (stability) and the deformation (flow) at that point, which are critical for designing durable asphalt pavements.

Superior Frame Construction

Built with heavy-duty steel, this apparatus is designed to withstand rigorous laboratory or industrial use. Its robust frame offers stable testing conditions and extends equipment lifespan, thanks to powder-coating and corrosion-resistant finishing.

Advanced Digital Control System

Featuring a microprocessor-based digital control unit, users can manage tests efficiently and toggle between kN and kg measurement units. This ensures greater accuracy and flexibility in compliance with major international standards.

Efficient Data Management

Collect and manage data seamlessly via USB and RS232 interfaces, supporting straightforward data transfer and printing for analysis or records. This enhances productivity and ensures traceability of test results.

FAQ's of Digital Marshall Stability Test Apparatus:
