Introduction
India’s Road Infrastructure Boom 2025 Bitumen, Emulsion & Smart Highways Driving Growth
The New Era of Road Infrastructure in India
India's road infrastructure is undergoing a transformative phase in 2025, with mega expressways, tunnel roads, and world-class connectivity projects reshaping the country's logistics and economic potential. From the Nagpur-Mumbai Samruddhi Mahamarg to Bengaluru's tunnel corridors, each project signifies India's commitment to connectivity and sustainable growth.
We supply Modified Bitumen Grades like PMB and CRMB, which are ideal for Indian expressways and tunnel corridors. Check Modified Bitumen options here.
Behind this revolution are the essential materials-Bitumen and Emulsion-forming the backbone of these modern roads.
Roads like the Samruddhi Mahamarg demand high-performance materials like VG-30 and VG-40 Bitumen. Explore our Bitumen product range that meets NHAI and MoRTH standards.
Section 1: Samruddhi Mahamarg – A Green Corridor Revolution
The 701 km Nagpur-Mumbai Samruddhi Expressway is now fully operational as of June 5, 2025. Connecting 24 districts across Maharashtra, it's one of India's largest greenfield expressways.
- Travel Time Reduction: Cuts travel time from 18 to 8 hours.
- Environmental Initiatives: 3.3 million trees planted along the corridor.
- Wildlife Crossings: Over 100 crossings built to preserve biodiversity.
- Economic Impact: Boosts agriculture, logistics, tourism, and exports.
- Sustainability Features: Incorporates solar power projects and a vast gas pipeline for industrial decarbonization.

This expressway utilizes modified bitumen and advanced emulsion binders to ensure durability in extreme Indian weather, reducing the need for frequent maintenance.
Section 2: Bengaluru Tunnel Roads – India's Urban Infrastructure Innovation
To alleviate Bengaluru's traffic congestion, the Karnataka government has approved two major underground tunnel corridors under the BOOT model (Build-Own-Operate-Transfer).
Project Details:
- Routes: Esteem Mall near Hebbal to HSR Layout/Silk Board and KR Pura to Mysuru Road.
- Estimated Budget: ?2.17 lakh crore.
- Concession Period: 30 years with toll collection.
- Tender Process: Global tenders to be invited within 7 to 10 days.

These corridors demand flexible paving materials, and Polymer Modified Bitumen (PMB) is expected to be a key construction component due to its heat resistance and longevity.
Section 3: Bihar's ?37,000 Crore Road Development Push
In a significant infrastructure boost for eastern India, Union Minister Nitin Gadkari announced ?37,000 crore worth of road development projects in Bihar.
Major Inclusions:
- Highway Expansion: 4-lane highway from Bakhtiyarpur to Rajauli.
- Railway Overbridge: Construction in Nawada.
- Road Widening: Projects in Gaya district.

For low-temperature applications in Bihar’s rural road development, our Bitumen Emulsion solutions are the most effective. Discover suitable emulsions for long-lasting results.
Rural infrastructure in Bihar will benefit significantly with the use of cold mix emulsions, ideal for low-traffic zones and budget-controlled areas.
Section 4: Bitumen and Emulsion in Road Construction
India's roads wouldn't be sustainable without bitumen and emulsion, two of the most essential road construction materials.
Why Bitumen and Emulsion Matter:
- Bitumen: Offers weather resistance and high tensile strength for highways.
- Emulsion: Ideal for low-temperature applications, faster curing, and eco-friendly practices.
- Modified Bitumen (CRMB/PMB): Used for high-traffic zones like expressways and tunnel roads.
Government tenders and EPC contractors in India are now shifting to eco-friendly emulsions for sustainable infrastructure, aligning with the PM Gati Shakti Masterplan.
Section 5: Future Outlook – Smart Roads, AI, and Sustainability
India's infrastructure growth is not just about roads-it's about smart mobility, AI-driven toll systems, and climate-resilient materials.
Upcoming Trends in India:
- AI-Based Monitoring: Road condition monitoring using artificial intelligence.
- IoT Integration: Use of Internet of Things in road maintenance.
- Geo-Synthetic Materials: Adoption of geo-synthetic reinforced materials for durability.
Why You Should Watch the Road Infrastructure Sector Closely
From the Samruddhi Mahamarg to emulsion-based rural roads, India is paving its future-literally. Whether you're a road material supplier, EPC contractor, policymaker, or an informed citizen, understanding how bitumen and emulsion are shaping India's next-gen highways is crucial.
FAQs for the help of Road Infrastructures
Q1: What is the use of emulsion in road construction?
A1: Emulsion is a mix of bitumen and water used for cold applications, offering cost-effective and eco-friendly road maintenance.
Q2: What is PMB in bitumen?
A2: PMB (Polymer Modified Bitumen) is enhanced with polymers for high performance, especially used in highways and tunnels.
Q3: Which is the longest expressway in India as of 2025?
A3: The Nagpur-Mumbai Samruddhi Mahamarg, at 701 km, is one of the longest and most advanced expressways in India.
