GRY-II sand cone (sand replacement) apparatus for in-place density of soil, gravel and base layers during compaction control.
Overview
The GRY- GRY-II Sand Replacement Density Apparatus is used for on-site measurement of the density of undisturbed sand and gravel soil. In the test, standard sand is poured into the test pit, and the unit weight of the tested material is calculated based on the mass of the poured sand and the volume of the test pit. It is suitable for on-site density testing of subgrades, base courses, sub-base courses and other construction layers.

FAQ
Q1: What standards does the GRY-II Sand Replacement Density Apparatus comply with?
A1: The GRY-II Sand Replacement Density Apparatus 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 GRY-II Sand Replacement Density Apparatus 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.
