The Marshall Stability Test Apparatus measures the stability (maximum load) and flow of a compacted bituminous mix specimen, the core parameters of Marshall mix design. It is used to fix the optimum binder content and to verify job mixes for bituminous macadam, DBM and bituminous concrete under MoRTH specifications.

What this equipment tests

  • Marshall stability and flow of bituminous mixes
  • Optimum binder content determination
  • Job-mix formula verification (BM / DBM / BC)

Applicable Indian Standards

  • ASTM D6927 — Marshall stability and flow of bituminous mixtures
  • MoRTH — Specifications for road and bridge works — flexible pavements
