Asphalt penetration tester with standard needle, water bath and digital displacement reading to determine penetration grade of bitumen.
Overview
The NC asphalt penetration tester is used to determine the penetration of asphalt materials and evaluate the consistency, hardness and high-temperature stability of asphalt. The instrument consists of a needle rod, a standard needle, a sample dish, a constant temperature water bath, a lifting mechanism, a displacement measuring device and an NC control system. It is suitable for asphalt performance testing in road engineering, asphalt 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
• 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 Asphalt Penetration Tester comply with?
A1: The Asphalt Penetration Tester 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 Asphalt Penetration Tester 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.
