Subgrade Test
Road QC Subgrade Test Report Excel is a complete, ready-to-use documentation sheet designed exclusively for Subgrade quality control in highway and road projects. This professionally developed QC format enables site engineers, contractors and consultants to record and verify all mandatory laboratory and field test results without manual formatting, calculation errors or skipped checkpoints — ensuring smooth approval during inspections and technical audits.
Subgrade is the compacted natural soil layer that forms the foundation of the pavement system, directly supporting all granular and bituminous layers above it. Its strength, stiffness and moisture behavior determine the long-term performance of the entire road structure. Any deviation in plasticity, moisture content, compaction, dry density or CBR strength can result in differential settlement, pavement cracking and premature surface failures. This Subgrade QC sheet ensures every performance-critical parameter is accurately measured and documented, preventing structural weaknesses from progressing into the upper pavement layers.
📌 Key Tests Covered in the Subgrade QC Excel
The sheet includes the complete set of essential Subgrade QC testing formats, including:
✔ Grain Size Analysis
✔ Atterberg Limits
✔ Proctor Test
