Focus of IRC SP 94 on Material Testing in Highway Sector
The standard emphasizes critical tests for highway construction materials, summarized as follows:
[ \text{CBR} = \frac{\text{Load at specific penetration}}{\text{Standard load}} \times 100% ]
| Test Parameter | Standard Limit/Range | Purpose |
|---|---|---|
| Aggregate Crushing Value | Less than 30% (base course) | Aggregate strength |
| Bitumen Penetration | 40–60 (Penetration Grade 60/70) | Bitumen consistency |
| Concrete Compressive Strength | Minimum 20 MPa (pavement) | Structural integrity |
