DC-3 pneumatic rut slab compactor prepares asphalt mixture specimens for wheel tracking tests with stable compaction pressure and settable passes.
Overview
The asphalt mixture rut test molding machine is used to prepare asphalt mixture rut test specimens in the laboratory, and can compact and form asphalt mixtures of different specifications to provide standard specimens for rut testing. Adopting pneumatic loading, the instrument features stable compaction pressure, settable rolling times, convenient operation and good molding effect. It is suitable for road engineering, asphalt mixture production enterprises and laboratories.

FAQ
Q1: What standards does the DC-3 Pneumatic Asphalt Rut Slab Compactor comply with?
A1: The DC-3 Pneumatic Asphalt Rut Slab Compactor 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 DC-3 Pneumatic Asphalt Rut Slab Compactor 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.
