Electric sand patch tester that spreads sand at constant speed for more consistent texture depth results on asphalt and concrete pavements.
Overview
This instrument is used to test the surface texture depth of asphalt and non-grooved cement concrete pavements to evaluate skid resistance. Compared with the manual sand-patch method, the electric method uses a motor to drive the sand funnel at a constant speed for uniform sand spreading with reduced human error and standardized testing. Complies with JTG 3450-2019 T0962. It consists of a main unit, a control box, a sand funnel and a scale. Easy to operate and portable.
Applications

FAQ
Q1: What standards does the Electric Sand Patch Texture Depth Tester comply with?
A1: The Electric Sand Patch Texture Depth Tester 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 Electric Sand Patch Texture Depth Tester 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.
