The Marshall Mould – 150 mm diameter is a precision-manufactured laboratory apparatus used for preparing cylindrical specimens of bituminous paving mixtures for the Marshall Stability and Flow Test, especially for mixes containing larger aggregate sizes. The larger mould size ensures proper accommodation and compaction of coarse aggregates, resulting in accurate evaluation of the strength and deformation characteristics of asphalt mixes.

The Marshall Breaking Head – 100 mm is a precision-engineered attachment used with the Marshall Stability Testing Machine to apply compressive load on standard 100 mm diameter Marshall specimens. It consists of upper and lower curved segments designed to uniformly distribute load over the specimen during testing, ensuring accurate determination of Marshall Stability and Flow values. The breaking head is manufactured from high-quality hardened steel for strength, durability, and repeatable performance.

A manual compaction hammer used in preparing asphalt specimens according to Marshall Mix Design procedures for determining stability, flow, and voids in bituminous mixes. Commonly used in quality control labs, road construction testing facilities, and materials laboratories.
