Surface vibratory compactor for maximum dry density of cohesionless, free-draining coarse-grained soils and rockfill materials.
Overview
This instrument is suitable for determining the maximum dry density of cohesionless free-draining coarse-grained soil and coarse-grained soil (including rockfill materials). Its working principle is to apply vertical vibration to the sample in the test cylinder through a vibration mechanism, so that the particles tend to be arranged more closely, simulating the field vibration compaction effect, and providing a basis for compaction quality inspection of fillers in subgrade, dam, rockfill and other projects.
Applications
• Road and highway engineering laboratory testing
• Construction material quality control and acceptance
• Research and teaching laboratories
• Third-party inspection and certification bodies
Features
• 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 Surface Vibratory Compactor comply with?
A1: The Surface Vibratory 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 Surface Vibratory 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.
