Mild Steel Marshal Compaction Mould

About Mild Steel Marshal Compaction Mould

Mild Steel Marshall Compaction Mould is a high-quality laboratory testing apparatus used for preparing bituminous (asphalt) specimens in the Marshall Stability Test. It is manufactured from premium-grade mild steel and designed to provide accurate and repeatable specimen formation for evaluating the strength and stability of asphalt mixtures.

The mould assembly typically consists of a cylindrical mould body, detachable base plate, and extension collar, ensuring proper compaction and uniform specimen size. It is suitable for use with both manual and automatic Marshall compactors.

The mould is widely used in civil engineering laboratories, road construction projects, and quality control testing facilities.

Working Principle

The hot mix asphalt is placed inside the mould and compacted using a Marshall compactor with a specified number of blows. The mould ensures uniform shape and density, enabling accurate determination of stability and flow values.
