Asphalt Calculator India: Bitumen Tonnage, Volume & Cost (₹) Estimator
भारत में सड़क, ड्राइववे और पार्किंग परियोजनाओं के लिए मुफ्त ऑनलाइन कैलकुलेटर। Estimate hot mix asphalt and bituminous concrete (BC, DBM, BM) in metric units, with ₹ cost guidance for Indian projects.
Asphalt & Bitumen Calculator (Metric, India)
This calculator uses the standard hot mix asphalt density of 2,322.7 kg/m³ (≈ 145 lbs/ft³). Enter dimensions in meters and thickness in centimeters — the default for highway, NHAI and PWD specifications in India.
Asphalt & Bitumen in India — MoRTH Specifications
Indian road works generally follow MoRTH (Ministry of Road Transport & Highways) specifications. Common mix types include:
- Bituminous Concrete (BC): wearing course, 40–50 mm thick.
- Dense Bituminous Macadam (DBM): binder course, 50–100 mm thick.
- Bituminous Macadam (BM): base course, 50–75 mm thick.
- Mastic Asphalt: bridge decks and heavy-duty surfaces.
Approximate Asphalt Price in India (2026)
| Material | Approx. Price (₹/tonne, delivered) |
|---|---|
| Bituminous Concrete (BC) | ₹6,500 – ₹9,500 |
| Dense Bituminous Macadam (DBM) | ₹6,000 – ₹8,800 |
| Bituminous Macadam (BM) | ₹5,500 – ₹8,000 |
| VG-30 / VG-40 Bitumen (binder only) | ₹55,000 – ₹70,000 / tonne |
Prices vary widely with crude oil, aggregate availability, plant location, GST and transport cost. Use ₹7,500/tonne as a working midpoint for BC; confirm with your supplier.
Quick Tonnage Reference (Metric — India)
| Thickness | Coverage per Tonne | Tonnes per 100 m² |
|---|---|---|
| 40 mm (BC wearing course) | ~10.8 m² | ~9.3 tonnes |
| 50 mm | ~8.6 m² | ~11.6 tonnes |
| 75 mm (DBM) | ~5.7 m² | ~17.4 tonnes |
| 100 mm | ~4.3 m² | ~23.2 tonnes |
Calculation Formula
- Volume (m³) = Length (m) × Width (m) × (Thickness in cm ÷ 100)
- Weight (kg) = Volume × 2,322.7
- Tonnes = Weight ÷ 1,000
Worked Example: 1 km × 7 m Road, 50 mm BC
- Volume: 1,000 × 7 × 0.05 = 350 m³
- Weight: 350 × 2,322.7 = 812,945 kg
- Tonnes: ≈ 813 tonnes
- With 10% buffer: ≈ 894 tonnes
Project Planning Notes for India
- Monsoon scheduling: plan paving between October and May where possible.
- GST applicable: typically added on top of quoted material price.
- Supplier confirmation: ex-plant vs. FOR-site pricing must be clarified.
- For NHAI and state highway works, all materials must meet MoRTH specifications.
Frequently Asked Questions
What is the density of bitumen concrete in India?
Standard BC has a density of about 2,300–2,400 kg/m³, in line with the 2,322.7 kg/m³ default used here.
How much bitumen do I need for 1 km of road?
A 7 m wide, 50 mm BC layer = 350 m³ ≈ 813 tonnes. With 10% buffer → ~895 tonnes.
What is the price of asphalt per tonne in India?
Bituminous Concrete typically costs ₹6,500–₹9,500 per tonne delivered, depending on region and crude oil prices.
Can I switch to imperial units?
Yes — change the unit toggle at the top of the form.
