Balanced Mix Design Frame

SKU: CS-BMD9500 Category: Tags: ,

The Cox & Sons multi-purpose loading system – Perform BMD and standard mix tests with quality and precision

The Balanced Mix Design Frame provides the ultimate solution for a lab looking to perform the key new BMD tests IDEAL-CT, IDEAL-RT, I-FIT, and SCB. Additionally, it can be used to perform standard laboratory tests such as Marshall, TSR, and interlayer shear bond.
More information on Balanced Mix Design can be found here.
The Cox and Sons BMD 9500 is the market-leading load frame for labs that need to run balanced mix design tests. Unique PID control lifts the machine above other screw driven machines with highly accurate speed control and provides servo control performance at a fraction of the price.


  • IDEAL-CT (TTI Method) — ASTM D8225
  • IDEAL-RT (TTI Method) — ASTM WK71466
  • I-FIT (SCB IL Method) — AASHTO TP124
  • SCB (LSU Method) — ASTM D8084
  • TSR — AASHTO T283
  • ISS (Interlayer Shear Strength) — AASHTO TP114
  • TxDOT (Interlayer Shear Strength) – Tex-249-F
  • Marshall — ASTM D6927, AASHTO T245
  • BS EN 12697-23

Balanced Mixed Design Frame CS-BMD9500 is able to perform IDEAL-CT ASTM, SCB AASHTO(I-FIT), IDEAL-RT ASTM, SCB ASTM (Louisiana), Tack Bond Shear AASHTO, Marshall, Leutner, and TSR.

For key BMD tests, the results are calculated on the machine. This feature removes the awkward procedure of downloading data and transferring it to a PC in order to be calculated and displayed. This also gives operators the opportunity to quickly determine whether the design of a sample mix is within spec. Of course, if required data can easily be transferred to a PC for reports or further research.

Key Features

  • PID software algorithm produces servo-hydraulic rivalling displacement control
  • Super stiff frame to minimise frame flex during tests
  • Instant on-screen test results – no need to transfer data to a PC
  • Analysis for IDEAL-CT, IDEAL-RT, I-FIT, and ASTM SCB
  • Included in NCAT BMD machine assessment
