Roadwork Layer Take‑Off Calculator
Chainage‑based volumes + materials (cement, asphalt binder, granular mass, coats, joints steel, sealant) with Standards Profile. Includes a simple cost estimate based on 2025 construction cost indices for India, the US and the UK.
Input: Chainage blocks (start, end, width). Then adjust layer thickness & parameters. Profile applies ranges & checks automatically. Choose your market to apply the corresponding cost index.

Profiles set typical ranges (thickness, binder %, coats, densities, joints). Out‑of‑range inputs are flagged.
What This Roadwork Calculator Does & How to Use It
All Quantities Auto Export CSV • Print-readyWhat this calculator does
This tool computes chainage-wise volumes for each pavement layer and turns them into the practical quantities you need on site and in BOQs—automatically.
- Volumes by layer & chainage → m³ for GSB, WMM/WBM, CTB/DLC/PQC, asphalt lifts.
- Materials → cement tonnage by grade, asphalt mix mass & bitumen content, granular mass from density.
- Surface treatments → prime & tack coat litres based on area and interfaces.
- Rigid pavement joints → dowel & tie-bar steel weight and joint sealant length (configurable spacing & sizes).
- Outputs → clean tables, Export CSV, and printer-friendly layout.
Everything updates as you tweak chainage blocks, widths, thicknesses, grades, densities, binder %, and joint parameters.
How to use the calculator
- Select a road type that matches your project (layers load automatically).
- Add chainage blocks—enter Start CH, End CH, and Width for each segment.
- Confirm layer thicknesses (mm). For concrete layers, pick the grade. For asphalt layers, enter binder %.
- Open Advanced Settings to adjust densities, water-cement ratio, coat rates, and joint parameters.
- Hit Calculate (or keep Auto-recalculate on) to generate the volume and material breakdown.
- Use Export CSV to download tables for BOQ take-off or attach to your submittals.
