Key Takeaway: By integrating AutoCAD's
DATAEXTRACTION command with Excel, site engineers can reduce quantity calculation time by 70% and eliminate manual entry errors.
Step-by-Step Road Construction Quality Control Process on Site
Introduction
Quality control in road construction is essential to ensure durability, safety, and long life of the pavement. A site engineer must follow proper procedures at every stage.
1. Subgrade Preparation
- Remove all soft soil and debris
- Compact soil properly
- Check moisture content before compaction
2. Sub-base and Base Layer Control
- Check material grading
- Maintain proper thickness
- Ensure compaction as per specification
3. Field Density Test (FDT)
- Conduct sand replacement test
- Ensure required density is achieved
- Record results in QC register
4. Bituminous Layer Control
- Maintain correct temperature of mix
- Ensure proper rolling pattern
- Avoid segregation of material
Conclusion
Proper quality control ensures long-lasting and strong road performance.
