Automatic Marshall Compactor

HT-722-1

Reference Standards: ASTM D1559, ASTM D6926, AASHTO T245

The Automatic Marshall Compactor is designed to prepare bituminous specimens with uniform density and compaction energy. The equipment simulates field compaction by applying repeated blows from a standard hammer falling from a specified height. The compaction process ensures proper aggregate interlocking and binder distribution, which directly affects stability and durability of the mix. The automated mechanism eliminates operator variability, providing highly repeatable and consistent specimens for accurate Marshall testing.

Key Features

  • Fully automated operation with programmable blow count
  • Precision-guided hammer for uniform impact distribution
  • Digital counter for blow tracking
  • Safety enclosure with interlock system

Technical Specifications

  • Hammer weight: 4.54 kg ± 0.01 kg
  • Drop height: 457 mm ± 5 mm
  • Blow count: Programmable
  • Power supply: 230V, 50 Hz
  • Motor: Geared motor with controlled speed
