IRC 73:1980 — Geometric Design Standards for Rural (Non-Urban) Highways
Reference summary — verify against the current edition of the code before you rely on it in practice. Free tier available — start free.
Geometric design — sight distance, curves, superelevation, gradients.
Issued by IRC · Governs Transportation Engineering
Provisions most often examined
- Superelevation \(e + f = V^2/127R\)
- \(e_{\max} = 0.07\) (plain/rolling)
- Design speed and sight distances
These are the provisions that recur in ESE, GATE and SSC JE question papers, not a complete list of the code's clauses. Mock Test Mitra is a practice platform, not a standards body — read the code itself for authoritative text.
