DC-20A single-column automatic asphalt mixture mixer with microcomputer control and temperature control for laboratory specimen preparation.
Overview
The single-column asphalt mixture automatic mixer is used for automatic mixing of laboratory asphalt mixtures, and is suitable for sample preparation in road engineering, asphalt production enterprises and testing institutions. Adopting advanced microcomputer control technology, the instrument features one-button control, automatic lifting, delayed start, automatic mixing, temperature control and time setting. It consists of a single-column main unit, a mixing head, a heating mixing bowl, an operation panel, a lifting mechanism and a temperature control system. It is compact in structure, convenient to operate and mixes evenly.
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
• Robust construction suitable for both laboratory and field use
• Compliant with relevant Chinese and international testing standards
• Complete with calibration certificate and operation manual

FAQ
Q1: What standards does the DC-20A Automatic Asphalt Mixture Mixer comply with?
A1: The DC-20A Automatic Asphalt Mixture Mixer 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 DC-20A Automatic Asphalt Mixture Mixer 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.
