Mild Steel Electric Marshall Stability Test Apparatus

The Marshall Stability Testing Machine is designed for determining the stability and flow values of bituminous mixtures, used in the design and evaluation of flexible pavements. The system measures the resistance of cylindrical bituminous specimens to plastic flow under a specific load, temperature, and deformation rate.

This apparatus features a rugged, heavy-duty frame capable of applying a load up to 50 kN at a controlled rate of 50 ± 5 mm/min. A safety cut-off switch ensures operator protection, and digital indicators precisely display stability and flow values. The unit operates on 380 V AC and is ideal for laboratories engaged in road construction quality control and material testing.
