LS-EXT-V Automatic Asphalt Analyzer with Mechanical Shaker
LS-EXT-V Automatic Asphalt Analyzer with Mechanical Shaker is a asphalt content ignition furnace and asphalt extraction equipment for ASTM D2172, AASHTO T164 workflows. The system employs a differential mass method for binder content determination and simultaneously recovers extracted binder for downstream performance evaluation, supporting reclaimed asphalt pavement (RAP) research programs. Distinguished by its integrated mechanical shaker and aggregate sieving subsystem, the LS-EXT-V delivers superior separation performance on difficult-to-process mixtures where conventional ultrasonic methods alone are insufficient. The complete closed-loop architecture — comprising washing with sieving, centrifugal separation, drying, and solvent distillation — ensures full operator safety within a sealed environment.
Mechanical Shaker & Aggregate Sieving System
The defining feature of the LS-EXT-V: an integrated mechanical vibration shaker with aggregate classification capability. This physical agitation mechanism delivers dramatically superior separation performance on rubberized asphalt, crumb rubber modified (CRM) binders, and SMA mixtures where high binder viscosity resists conventional ultrasonic dissolution alone.
Fully Sealed Closed-Loop Operation
The entire extraction and solvent recovery process occurs within a hermetically sealed system, effectively eliminating toxic solvent vapor exposure. This architecture drastically reduces solvent consumption and ensures full compliance with modern HSE (Health, Safety & Environment) regulations.
Ultrasonic-Assisted Heated Washing
The washing chamber integrates a high-power heating element with an industrial ultrasonic transducer for dual-action cleaning. Combined with the mechanical shaker, this triple-action system (heat + ultrasonics + vibration) provides the most thorough separation available for difficult modified binders.
Integrated Drying & Aggregate Recovery
The built-in drying subsystem automatically dehydrates recovered aggregates and mineral filler, enabling immediate weighing for binder content calculation. Collected aggregates are ready for subsequent sieve analysis without additional sample preparation.
Automated Solvent Distillation & Recovery
A high-efficiency distillation system automatically reclaims and purifies used solvent for reuse through an advanced closed-circuit cooling unit that outperforms traditional tap-water cooling methods while conserving water resources.
Vacuum Rotary Evaporator Sampling (Optional)
An optional vacuum rotary evaporator interface enables direct extraction of binder-solvent samples with a configurable pre-soak period of 3 to 30 minutes, facilitating downstream recovered binder performance testing (viscosity, DSR, BBR) for RAP evaluation.
