The internal balance monitors sample mass throughout ignition and the controller detects the configured test endpoint.
Follow sample mass loss and chamber temperature on the touchscreen during each test.
An internal calibration weight supports routine balance checks without dismantling the weighing system.
The afterburner oxidizes combustion gases before exhaust. Suitable laboratory ventilation and safe installation are still required.
Export test results for laboratory records and downstream review without manually transcribing every reading.
Save mixture-specific ignition settings for repeat testing. Validate each procedure and aggregate correction factor before use.

The LS-TC30 is an automatic asphalt content ignition furnace for ASTM D6307 and AASHTO T308 workflows. A prepared sample is weighed and heated while the internal balance monitors mass loss. After the endpoint is detected, the laboratory applies its validated aggregate correction factor to report binder content. This ignition method is also used for bitumen content determination in asphalt mixtures.
A prepared asphalt-mixture sample is weighed, heated in the furnace, and monitored as combustible binder is removed. The integrated balance tracks mass loss and the control system ends the cycle when the configured stability criterion is reached. The laboratory then applies the validated correction factor required for its aggregate, mixture, and equipment combination.
Some aggregates gain or lose mass at ignition temperatures, so raw mass loss is not automatically equal to binder content. Laboratories should establish and document a correction factor in accordance with the applicable method and their own mix/equipment combination, then confirm it when aggregate source or mixture design changes.
NCAT furnace is a historical industry term associated with early adoption of the ignition method for asphalt binder-content testing. Today, laboratories also use asphalt content ignition furnace, asphalt ignition oven, and burn-off oven for equipment based on the same principle: determining binder content from corrected mass loss during ignition. LS-TC30 is Lithostek's implementation of this equipment type, configured for ASTM D6307 and AASHTO T308 with integrated weighing, endpoint control, and a high-temperature afterburner.
The chamber operates up to 600 °C and the integrated afterburner up to 900 °C to oxidize combustion gases before exhaust. The furnace still requires suitable installation clearances, ventilation, electrical service, heat-resistant handling procedures, and site-specific risk controls defined by the laboratory.
Before ordering, confirm sample baskets and trays, basket quantity, heat-resistant tools, ventilation connection, 380 V three-phase supply, calibration route, balance verification weights, data-export format, spare heating elements, installation, training, and any destination-specific documentation. Included and optional items should be confirmed in the quotation rather than assumed from a generic list.
| Factor | Ignition furnace | Solvent extraction |
|---|---|---|
| Measurement principle | Binder is burned off and content is calculated from corrected mass loss. | Solvent extraction dissolves binder before aggregate and solution separation. |
| Solvent use | No extraction solvent is required for the binder-content cycle. | Requires a method-compatible solvent and recovery controls. |
| Recovered binder | Binder is consumed and cannot be recovered for further testing. | Binder can be recovered when the selected workflow supports recovery. |
| Recovered aggregate | Aggregate remains for gradation checks after cooling and correction. | Aggregate and mineral filler are separated, dried, and recovered. |
| Typical selection reason | Routine binder-content QC with automated mass monitoring. | Binder recovery, solvent-based specification, or mixtures requiring extraction analysis. |
Request a quote with your destination country and laboratory requirements. Ask for the equipment price, supplied baskets and handling tools, optional spares, installation support, shipping, lead time and warranty terms. The quotation confirms the supply scope; accessories are not assumed to be included.
Listed supply: 380 V, three-phase, 15 A. A suitable exhaust connection is required. Include your voltage and frequency if different so we can check suitability before quoting. The 900 °C afterburner oxidizes combustion gases before exhaust; it does not remove the need for laboratory ventilation, installation clearances and safe hot-sample handling.
Maximum sample capacity is 3,500 g, with a recommended working range of 1,200–1,800 g. Typical testing takes 20–50 minutes, depending on the mixture and validated procedure. Select sample mass according to the applicable method and aggregate size. The 0.1 g balance specification is resolution, not a guarantee of binder-content accuracy.
The listed methods are ASTM D6307 and AASHTO T308. Include the required method edition and any local acceptance requirements in your inquiry. EN 12697-39 suitability must be confirmed separately before purchase.
Some aggregates change mass during ignition, so raw mass loss is not automatically equal to binder content. Establish the correction factor for the aggregate, mixture and furnace according to the applicable method, and review it when those conditions change.
NCAT furnace is a historical industry term associated with ignition-method binder-content equipment. Asphalt ignition oven and asphalt content ignition furnace describe the same equipment family. LS-TC30 is Lithostek's implementation of this equipment type, with integrated weighing, endpoint control and a high-temperature afterburner.
Choose ignition for routine binder-content testing with automatic mass monitoring and no extraction solvent. The binder is consumed, while the remaining aggregate can be assessed for gradation after cooling under the applicable procedure. Choose solvent extraction and a suitable recovery system when recovered binder is needed for further testing or the specified method requires extraction.
