It performs raw material pre-treatment and precise mixing of loose asphalt mixtures, providing qualified materials for Marshall stability tests, wheel tracking tests, and other laboratory specimen preparation. It also supports research activities including new mix design development, recycling agent performance evaluation, and process parameter optimization. The equipment features small-batch operation, high precision, and excellent repeatability.

Standard

JTG 3410-2025 T0740

Product Advantages

The equipment is equipped with our proprietary elastic mixing paddle and oil-bath heating temperature control system. The unique mixing structure ensures stable operation, reduces material sticking during mixing, improves heating efficiency, and better meets the characteristics of asphalt mixtures.

The equipment fully complies with the latest industry standard JTG 3410-2025 T0740 “Preparation Method of Asphalt Mixture Specimens”, ensuring accurate, reliable, and repeatable asphalt mixture preparation and providing reliable technical support for asphalt material performance evaluation.

Key Features

• Unique 3D Mixing Design
  The innovative paddle kinematics model and elastic structure generate simultaneous axial and radial movement of materials during rotation, creating complex vortices and effectively reducing mixing dead zones.

• Combination of Revolution and Rotation
  The mixing system revolves around the center of the mixing bowl while the paddles rotate at high speed around their own axes, generating strong shearing action and improving mixing performance for asphalt mixtures.

• Efficient Oil-bath Heating System
  The mixing bowl adopts an oil-bath heating system, providing faster heating, lower energy consumption, and shorter mixing cycles.

• Intelligent Temperature Control System
  Thermal oil circulation inside the jacket, combined with a PT100 temperature sensor and temperature control module, enables PID precise temperature control and ensures stable material temperature throughout the mixing process.

• Interlock Safety Protection
  The mixing process stops automatically when the lid is opened. The discharge valve and mixing system are interlocked to ensure safe operation.

• Easy Maintenance Design
  The modular structure and quick-release design simplify equipment cleaning and maintenance procedures.
