JM-III accelerated polishing machine for aggregate polished stone value (PSV) to evaluate skid resistance of road aggregates.
Overview
The JM- JM-III Accelerated Polishing Machine is suitable for accelerated polishing of aggregate surfaces to evaluate the skid resistance and wear resistance of aggregates. The equipment consists of a main unit, transmission mechanism, guide wheels, pressing device, grinding wheel or polishing wheel assembly, etc. By simulating the wear effect of vehicle tires on aggregates, it provides a basis for aggregate selection and quality evaluation in road engineering.

FAQ
Q1: What standards does the JM-III Accelerated Polishing Machine comply with?
A1: The JM-III Accelerated Polishing 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 JM-III Accelerated Polishing 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.
