Automatic reflux centrifugal extractor for fast asphalt content testing of asphalt mixtures in road labs, mixing plants and inspection agencies.
Overview
The automatic asphalt mixture centrifugal extractor is used for asphalt content testing in asphalt mixtures. It adopts the return-flow centrifugal extraction method to quickly separate asphalt from aggregate, and is suitable for asphalt content detection in road engineering, asphalt mixture production enterprises, supervision institutions and laboratories. The instrument consists of a centrifugal extraction main unit, a heating return system, a solvent recovery device, a numerical control display unit, an operation panel and a frame. It features high automation, good separation effect, fast detection speed and convenient solvent recovery.
Applications
• Hot mix asphalt (HMA) laboratory mix design and quality control
• Asphalt plant production monitoring and batch certification
• Road construction acceptance testing and pavement performance assessment
• Research institutions and highway engineering laboratories
Features
• Microcomputer-controlled operation with digital display for direct readout
• Automatic test cycle with data storage and report generation
• Large LCD display showing real-time test parameters and results
• Compliant with relevant Chinese and international testing standards
• Complete with calibration certificate and operation manual

FAQ
Q1: What standards does the Automatic Asphalt Mixture Centrifugal Extractor comply with?
A1: The Automatic Asphalt Mixture Centrifugal Extractor is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the Automatic Asphalt Mixture Centrifugal Extractor be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
