# Asphalt Pavement Quantity Calculation For 6km Road

## What is Asphalt?

Asphalt is a mixture of aggregates, binder (Bituminous),filler, used for constructing and maintaining all kind of roads, parking areas etc. Aggregates used for asphalt mixtures of crushed rock, sand, gravel and most common binder use in asphalt is bitumen. The asphalt pavement is usually done on the above of road formation level.

### How is asphalt produced?

Asphalt is produced in an asphalt plant. It can be a stationary plant or even a mobile mixing plant. Up to 800 tons per hour can be produced in an asphalt plant. The average production temperature of hot mix asphalt is between 150 and 180 ° C, but new techniques are now available to produce asphalt at lower temperatures.

Let's solve this example for better understanding. Example:

### Calculate the quantity of asphalt

Suppose we are going to construct a road top layer with asphalt. The length of the road is 6,000 m or width of the road is 9 m without shoulders. The thickness of the asphalt is going to be 15 cm. Calculate the quantity of asphalt required?

Given data:

Length (L) = 6km = 6,000 m Width (w) = 9m

Thickness (T) = 15cm = 0.15m Solution:

First of all we calculate the volume of asphalt

Volume:

= L x B x W

= 6,000 x 9 x 0.15 = 8100m3

Asphalt Quantity:

Density of asphalt is taken as 2330kg/m3

Quantity of asphalt = volume of road  x density of asphalt

= 8100 x 2330

= 18,873,000kg (dividing by 1000)

= 18,873 tons. Ans

Approximately we need 18,873 tons of asphalt for this road construction.
