Brookfield-type rotational viscometer with temperature control for asphalt binder viscosity, used to set mixing and compaction temperatures.
Overview
The Brookfield Rotational Viscometer for Asphalt is used to determine the Brookfield rotational viscosity of asphalt materials and evaluate their rheological properties, construction workability and high-temperature stability. The instrument consists of a rotational viscometer, a constant temperature water bath, a temperature control device, a speed measurement system and a data processing unit. It is suitable for asphalt performance testing in road engineering, asphalt production enterprises and scientific research 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 Brookfield Rotational Viscometer for Asphalt comply with?
A1: The Brookfield Rotational Viscometer for Asphalt 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 Brookfield Rotational Viscometer for Asphalt 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.
