The LHRS-6 is developed based on the standards set by the National Center for Asphalt Technology (NCAT) in the US, including ASTM D6307, AASHTO TP53-95, and BS DD250.
Unlike solvent extraction which uses hazardous chemicals to dissolve binder, the combustion method burns the asphalt binder into gas, leaving only the aggregate, making it faster, safer, and more eco-friendly.
The average testing time ranges from 20 to 30 minutes, significantly increasing laboratory throughput compared to traditional methods.
Yes, the LHRS-6 is designed to handle various asphalt mixture types, including polymer-modified and reclaimed materials, ensuring consistent accuracy across different binders.
The internal electronic balance monitors the sample weight in real-time; once the weight stabilizes according to the pre-set calibration factor, the micro-controller signals the end of the test.
For comprehensive analysis, we recommend pairing the LHRS-6 with the Asphalt Consistency Tester, Asphalt Mixture Wheel Rutting Tester, and Laboratory Asphalt Penetration Tester.
