Escalating tensions in West Asia are disrupting bitumen imports crucial for India's road construction projects, potentially derailing national highway expansion targets and rural connectivity under PMGSY Phase-III.

Key points

Strait of Hormuz tensions have led to a 20.5% year-on-year decline in bitumen imports (2.36 lakh tonnes in April 2026 vs 2.97 lakh tonnes in April 2025), directly impacting India's road construction capacity.

Bitumen, a petroleum byproduct accounting for 30-40% of India's road construction material, faces supply chain vulnerabilities with 99% of imports sourced from Iraq, UAE, Iran, Oman and Bahrain.

[GS3-Economy] Domestic bitumen production has stagnated at ~53 lakh tonnes annually despite a 61% expansion in National Highways (91,287 km in 2014 to 1.47 lakh km currently), creating import dependency.

Pradhan Mantri Gram Sadak Yojana (PMGSY) Phase-III faces implementation risks with 17,365 km of rural roads pending construction due to material shortages.

National Highway Authority of India (NHAI) is receiving complaints from contractors about price volatility and supply shortages, potentially delaying the 10,000 km highway target for FY 2026-27.

[GS2-Governance] The crisis exposes India's infrastructure planning gaps in securing critical material supply chains, despite flagship schemes like Bharatmala Pariyojana.

Domestic bitumen consumption dropped 33% in April-May 2026 (5.80 lakh tonnes) compared to 2025 (8.62 lakh tonnes), indicating project slowdowns.

Petroleum Planning and Analysis Cell data shows bitumen imports peaked at 32.44 lakh tonnes in 2023-24 before declining, costing India ₹9,000-10,000 crore annually.

Way Forward: India should diversify bitumen sources to non-West Asian suppliers, incentivize domestic refinery upgrades for higher bitumen yields, and establish strategic bitumen reserves akin to petroleum reserves for infrastructure continuity.

Key terms

Bitumen

A viscous petroleum byproduct used as binding material in road construction, derived from vacuum distillation of crude oil residue. For UPSC, its significance lies in connecting energy policy (crude refining) with infrastructure development (road construction) and import dependency challenges.

Strait of Hormuz

A critical maritime chokepoint between Oman and Iran through which 21 million barrels of oil pass daily. For UPSC, it represents India's energy security vulnerability, with 80% of oil imports and 99% of bitumen imports transiting this route, making it geopolitically sensitive.

Pradhan Mantri Gram Sadak Yojana (PMGSY)

A flagship rural infrastructure scheme launched in 2000 to provide all-weather road connectivity to unconnected habitations. For UPSC, it exemplifies decentralized planning (Article 243G) and its Phase-III (2019-25) aims to consolidate 1.25 lakh km rural roads, testing last-mile delivery systems.

National Highway Authority of India (NHAI)

An autonomous agency under MoRTH established in 1995 (NHAI Act, 1988) to develop/maintain National Highways. For UPSC, it's central to infrastructure governance, implementing Bharatmala Pariyojana (2017) for economic corridor development and PPP models in highway projects.
