Determines the oil absorption rate of lignin and other fibers used in asphalt pavements by constant-amplitude vibration sieving. Request a quote.
Overview
This instrument is designed per Appendix D (oil absorption) of JT/T 533-2020 "Fibers for Asphalt Pavement" to determine the oil absorption rate of lignin and other fibers used in asphalt pavements. A weighed mixture of fiber and mineral oil is poured into the sample sieve on top; the instrument vibrates at constant amplitude so that excess mineral oil drains through the sieve. After the set time it stops automatically with an alarm; the sieve with oil-bearing fiber is weighed and the oil absorption rate (as a multiple of the fiber mass) is calculated. The unit runs several samples simultaneously, vibrates uniformly, and uses a time relay to control the vibration time.

FAQ
Q1: What standards does the Fiber Oil Absorption Tester for Asphalt Pavement comply with?
A1: The Fiber Oil Absorption Tester for Asphalt Pavement 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 Fiber Oil Absorption Tester for Asphalt Pavement 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.
