How To Calculate the Asphalt Quantity For Road

Numerous individuals often mistake asphalt for bitumen. Despite common belief, asphalt and the bitumen are not the same from a technical standpoint. How To Calculate the Asphalt Quantity For Road.

Asphalt consists of a blend of aggregates, binder (bitumen), and sand. The aggregates utilized in asphalt mixtures may include crushed rock, sand, gravel and or slags.

How To Calculate the Asphalt Quantity For Road

Bitumen serves as the liquid adhesive that binds asphalt together, contrary to the common misconception of using the term bitumen interchangeably with asphalt.

Asphalt finds extensive application in the construction and upkeep of the various road types, including highways, urban and rural roads, parking lots, and pathways. The distinction between asphalt and bitumen will be elaborated upon in a separate piece.

In this context, the focus will be on outlining the method for determining the amount of asphalt required and its associated expenses for the road development. The calculation process is straightforward, requiring only a set of specific data.

surface course

For Example

Length of the road = L = Five km = 5000 m

Width of the road = W = Six m

Thickness of the asphalt = H = 15 cm = 0.15 m

Qty Of the Asphalt Calculation:

Volume of the asphalt = L x W x H

= 5000 x Six x 0.15 = 4500 m3

Here, the density of the asphalt is taken as 2330 kg/m3

Therefore, qty of the asphalt = Volume of the asphalt x Density of the asphalt

= 4500 x 2330 = 10485000 kg = 10485 tons

Cost of the asphalt:

Suppose the cost of the One ton asphalt is 6000 rs.

Cost of the asphalt = 10485 x 6000 = 62910000 rs

Quantity Of the Asphalt In Curved Road.

curve road

For Example

  1. Width of the road = W = Six m
  2. Thickness of the asphalt = H = fifteen cm = 0.15 m

Length of the curved road = (π x R x θ)/180 = (3.14 x ten x 100)/180 = 17.44 m

Volume of the asphalt for the curved road = Length x Width x Thickness

= L x W x H = 17.44 x Six x 0.15 = 15.696 m3

Qty of the asphalt for the curved road = Volume of the asphalt x Density of the asphalt

= 15.69 x 2330 = 36558 kg = 36.55 tons

Cost of the asphalt:

Suppose the cost of One ton asphalt is 6000 rs.

Cost of the asphalt = 36.55 x 6000 = 219300 rs

Note

If the area you are calculating has an irregular shape, it is recommended to divide it into multiple regularly-shaped sections. Then, apply the above method to calculate the volume and asphalt requirements for each section individually. Finally, add up the results to obtain the total volume and asphalt requirements for the entire area.
