Double-column testing machine for CBR, unconfined compressive strength and other strength tests of soils and base materials.
Overview
This machine adopts double-column support with a reasonable mechanical structure, which ensures the accuracy of the instrument. When a force-measuring ring or digital force gauge is installed, it can be used to measure the unconfined compressive strength, indirect tensile strength and other properties of various stabilized material specimens. This instrument is suitable for strength tests of stabilized soil and pavement materials, and can also be used for flexural tensile tests of cement concrete. It has good stability, simple operation, accurate and reliable test results. It can also be used for many other loading tests, and manual loading is available even when the power is off.
Applications
• Pavement roughness, rutting and skid resistance inspection
• Road maintenance management and pavement inventory surveys
• Airport runway and taxiway condition assessment
• Highway network-level pavement performance evaluation
Features
• High measurement accuracy with stable repeatability
• 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 Pavement Material Strength Testing Machine comply with?
A1: The Pavement Material Strength Testing Machine 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 Pavement Material Strength Testing Machine 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.
