AASHTO T164 Testing Equipment

AASHTO T164 testing equipment for extraction & ignition workflows in asphalt mix laboratories. Compare LS-EXT-D, LS-EXT-A, LS-EXT-V for QC, compliance, and...

Test Method Context

AASHTO T164 is commonly used by laboratories that need a standards-led extraction & ignition workflow for asphalt mix. The method is usually not just a machine requirement; it also defines how samples are prepared, conditioned, measured, reported, and compared against project or agency acceptance criteria. Laboratories searching by AASHTO T164 normally need equipment that can hold the correct specimen format, maintain stable control conditions, support repeatable operator routines, and produce data that can be reviewed by clients, road authorities, university supervisors, or third-party inspection teams. Lithostek treats the standard page as a method map: it connects the official AASHTO reference to the practical laboratory steps, the matching equipment families, and the configuration questions that should be answered before purchase.

Equipment Selection

For equipment selection, start with the material, specimen size, required capacity, control accuracy, and daily sample volume. AASHTO T164 equipment for extraction & ignition often requires more than the primary tester; laboratories may also need preparation tools, conditioning equipment, calibration accessories, data output, spare parts, and operator training. The matching Lithostek systems for this page include LS-EXT-D, LS-EXT-A, LS-EXT-V. These products are organized around ASPHALT MIX workflows so laboratory teams can compare automation level, measurement resolution, environmental control, safety enclosure, reporting format, and after-sales support without leaving the standard-number path.

Quality Control Notes

Quality-control teams should confirm the latest official AASHTO T164 document before finalizing a tender or laboratory SOP, because tolerances, conditioning details, and reporting fields can change by edition or local specification. In practice, the equipment quotation should reference the target standard, destination market, specimen type, throughput, power supply, calibration route, and any required acceptance test before shipment. Lithostek can review these details and configure the system around specimen preparation, controlled testing, reporting, calibration, and compliance review, helping laboratories avoid under-specified machines that pass a catalog comparison but fail daily repeatability or documentation requirements.

Related Standards

Related methods are useful when a laboratory needs a complete package rather than one isolated instrument. A AASHTO T164 request may sit next to other ASTM, AASHTO, EN, ISO, or local standards covering sample preparation, conditioning, strength, durability, dimensional checks, or reporting traceability. Use the standards index to move from AASHTO T164 into adjacent method pages, then open the linked product pages to compare the equipment scope, accessories, and application notes. This keeps equipment selection tied to the test method instead of relying only on generic category names.

LS-EXT-D

Digital Centrifuge Extractor

The LS-EXT-D is the essential solution for asphalt mixture testing. High-capacity digital centrifugal extractor for quantitative binder recovery using the centrifuge separation method as per ASTM D2172 and AASHTO T164. Ideal for determining asphalt content (or binder-aggregate ratio) in viscous petroleum asphalt mixtures for pavement construction quality control and in-service road condition surveys. Features an advanced vibration-dampening architecture with internal counterweighting for ultra-smooth, stable operation and a programmable soft-start motor.

LS-EXT-A

Automatic Closed-Loop Asphalt Analyzer

The LS-EXT-A is a fully automatic, computer-controlled asphalt mixture analyzer designed for the extraction and separation of binder, mineral filler, and rubber particles from asphalt mixtures using the centrifuge separation method. Employing a differential mass method for precise binder content determination, the system simultaneously recovers extracted binder for subsequent performance evaluation — providing critical data support for reclaimed asphalt pavement (RAP) recycling programs. The integrated closed-loop architecture encompasses washing, centrifugal separation, drying, and solvent distillation/recovery subsystems, ensuring the entire extraction process is completed within a sealed environment for maximum operator safety and minimal solvent emissions.

LS-EXT-V

Automatic Asphalt Analyzer with Mechanical Shaker

The LS-EXT-V is a specialized variant of the Lithostek automatic asphalt analyzer, purpose-engineered for the extraction and separation of binder and mineral filler from rubberized and highly viscous polymer-modified asphalt mixtures. 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.
