Asphalt is a mixture of aggregates, binder and filler, used for constructing and maintaining all kind of roads, parking areas but also play- and sport areas. Aggregates used for asphalt mixtures could be crushed rock, sand, gravel or slags. In order to bind the aggregates into a cohesive mixture a binder is used. Most commonly, bitumen is used as a binder. An average asphalt pavement consists of the road structure above the formation level which includes unbound and bituminous-bound materials. This gives the pavement the ability to distribute the loads of the traffic before it arrives at the formation level.
Breadth (B) = 8m
Depth of the road (W) = 15cm = 0.15m
Length (L) = 2km = 2000m
Therefore, the volume of asphalt = L x B x W = 2000 x 8 x 0.15 = 2400m3
Here, density of asphalt is taken as 2330kg/m3
Therefore, quantity of asphalt = volume of road section x density of asphalt
= 2400 x 2330 = 559200kg = 5592 tons (dividing by 1000).
One Comment on “How to Calculate the Quantity of Asphalt in Road Construction”
How did you get the density of alsphalt and show me how you calculate it thanks
