Rolling thin film oven that simulates short-term aging of asphalt binder during mixing and paving to evaluate its aging resistance.
Overview
The Asphalt Rolling Thin Film Oven (RTFO) is used to simulate the thermal aging process of asphalt during construction and service, and evaluate the aging resistance of asphalt through heating and rotating thin film test. The instrument consists of an oven main body, a rotating rack, a heating system, a temperature control system, a timing device and a control system. It is suitable for asphalt aging 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
• Precision temperature control with PID regulation and over-temperature protection
• 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 Rolling Thin Film Oven (RTFO) comply with?
A1: The Asphalt Rolling Thin Film Oven (RTFO) 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 Rolling Thin Film Oven (RTFO) 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.
