Asphalt Calculator for Free
Our Asphalt Calculator is designed to help you determine the exact amount or quantity of asphalt needed for your project. This calculator will helps you in determining all the of materials required for asphalt either it is wearing course asphalt or base course asphalt.

Asphalt Calculator Working
For Calculation of Asphalt and the materials used in asphalt mixture first of all we have to know few things. First of all we have to know the dimensions/size of the road or the asphalt required. Either we should know the Volume of the Asphalt required or We should have the measurement of the area where asphalt will be used so that we can find its volume.
Volume of Asphalt= Length of Road * Width of Road * Thickness of Road
Now we know the Volume of the Asphalt required.
Now we have to find what percentage of bitumen we actually require. If it is specified by client then we should go with that otherwise we have to understand that for what purpose we need asphalt. Does it is required for Asphalt Wearing Course or Asphalt Base Course. Here is the Standard Bitumen requirements with respect to type of course.
| Asphalt Layer | Bitumen Percentage (Standard) | Bitumen Percentage (Some Regions) |
|---|---|---|
|
Asphalt Base Course |
4.0% - 5.0% |
3.5% |
|
Asphalt Wearing Course |
5.0% - 6.0% |
4.0% |
Standard Stone Dust and Crush Volume for Asphalt Calculation
The amount of stone dust required for per ton of asphalt is 7 cubic feet. Similarly the standard crush volume required for per ton of asphalt is 18 cubic feet. It can be different in your case. You have option to change the volume of the crush and stone dust but when one material increases per ton other one will decrease in same weight ratio automatically.
How Asphalt Calculator Calculate Density of Asphalt
The density of asphalt is normally from 2.3 to 2.5 tons/m3, but it may change with the percentage of bitumen. A general formula to calculate the density with respect to the percentage of bitumen is:
Formula to Calculate Density of Asphalt= 2.3 + (Bitumen Percentage−4) × 0.1 tons/m3
Formula to Calculate weight of Asphalt in Ton
Total Weight of Asphalt in Ton= Volume × Density
How Asphalt Calculator Calculate Weight of Bitumen
Total Weight of Bitumen in Tons=(Bitumen Percentage/100)×Total Weight of Asphalt in Tons
Example to Calculate Asphalt Weight
Let’s assume:
- Length: 1 km
- Width: 4 meters
- Thickness: 3 cm
- Bitumen Percentage: 4%
Step 1: Convert Units
- Length in meters: 1 km
- Height in meters:
Step 2: Calculate Volume
Volume=1000 meters × 4 meters × 0.03 meters
Step 3: Calculate Density
Since the bitumen percentage is 4%, we use the standard density for 4% bitumen:
Density=2.3 tons/m3
Step 4: Calculate Total Weight
Total Weight=120 m3×2.3 tons/m3
Total Weight=276 tons
Step 5: Calculate Weight of Bitumen
Weight of Bitumen=(4/100)×276 tons
Weight of Bitumen=11.04
Result
- Volume: 120 m³
- Total Weight: 276 tons
- Weight of Bitumen: 11.04 tons
Now you can use these calculations to determine the amount of asphalt required for any road construction project based on the provided dimensions and bitumen percentage. For effective project management and budgeting, it’s essential to estimate construction costs accurately.
