Automatic Marshall compactor for forming asphalt mixture Marshall specimens with standard hammer energy, automatic blow counting and lifting.
Overview
The Automatic Marshall Compactor is used for forming Marshall specimens of asphalt mixtures. It compacts the asphalt mixture into specified specimens through standard hammer energy, which can be used for tests such as Marshall stability and flow value. The instrument consists of a main frame, a lifting mechanism, a hammer, guide rods, a specimen mold positioning device, a control system and a counting display unit. It is suitable for road engineering, asphalt mixture production enterprises and laboratories.
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 Marshall Compactor comply with?
A1: The Automatic Marshall Compactor 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 Marshall Compactor 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.
