Marshall Stability Tester – For Asphalt Mix Design and Evaluation
The Marshall Stability Tester is an essential laboratory instrument used to determine the stability and flow characteristics of bituminous mixtures. This device evaluates the load-bearing capacity and deformation resistance of asphalt by subjecting compacted cylindrical specimens to a compressive load under controlled conditions. The maximum load before failure—known as Marshall Stability—helps engineers design and validate asphalt mixes for various traffic and environmental conditions.
This tester is widely used in pavement design, quality control of road construction materials, and research & development applications.
Key Features of Marshall Stability Tester
User-Friendly Controls: Simple push-button system for operating the up, down, and stop functions of the platen.
Indicator Lights: Clearly display unit status and signal when the platen reaches its limit.
High-Precision Load Cell: Ensures accurate and repeatable measurement of load and flow characteristics.
Compact Design: Space-efficient unit ideal for laboratory use.
Load Capacity: Designed for loads up to 44.5 kN (approx. 50 kN), suitable for a variety of asphalt samples.
Applications
Bitumen Mix Optimization: Helps determine the optimum bitumen content for maximum durability and load resistance.
Material Performance Analysis: Used to evaluate asphalt materials under simulated load and temperature conditions.
Pavement Evaluation: Assesses the long-term performance of existing asphalt pavements through sample testing.
Design of Asphalt Pavements: Supports the design of roadways, highways, and airport runways under various traffic intensities.
