The post How to calculate the Quantity of Earthwork in the Road appeared first on Surveying & Architects.
]]>In this Article u will learn step-by-step guidelines for measuring the QTY of earthwork (soil) in the Road, railway & the canal work with the help of mean area method.
For explanation, the solution is given in the following example.
Example ? Calculate the QTY of the earthwork for an embankment with length 120 m and width ten m at the top. Side slope is given as 2:1 & depths at each Thirty m distance are 0.4, 0.6, 1.4, 1.2 and 0.8 m.
The calculation is the done through a table. The table contains various heads like Road station, depth, center area, side area, total area, mean area, intervals and Qty.
The work of the road will start from Zero point. So, in the road station column in the table, the values will be given as 0, 30, 60, 90, 120 (as distance is given as thirty m).
In the depth column, provide the values as 0.4, 0.6, 1.4, 1.2 & 0.8 m.
To calculate the center area, the following formula will be used.
B x d = Breadth or width x Depth
After putting the values, we get the following result.
10 x 0.4 = fore meter
In this way the other values can be determined easily.
Sd^{2}, here S denotes slope & d denotes depth.
Two x 0.42 = 0.32 m^{2} (as sloe is given by 2:1)
In this way, the other values can be determined easily.
The Total area will be calculated with the following formula.
Bd + Sd^{2} = Center Area + Side area
To determine the mean area, 1st, sum up the first 2 rows of total area & then divide it with Two i.e. 4.32 + 6.72 /Two = 5.52 meter. In this way, other values can be calculated.
The value of intervals is given as Thirty meter.
Mean area x Intervals.
After putting the values, we get the following result.
5.52 x 30 = 165.6 m^{2
}
In this way, the other values can be calculated.
Total filling or embankment will be determined by summing up all the Qty & it will be 1389.6 m^{3
}
So, the total QTY of soils for filling or embankment of the road = 1389.6 m^{3.}

]]>In this article, I will discuss how to calculate the ( QTY ) Quantity of the Asphalt & its cost for the road construction. The calculation is very easy, u only need some data.
There are many who get confused between the asphalt & bitumen. They think that asphalt & bitumen are the same, but technically they are not same.
Asphalt is the composite material mixture of the aggregates, binder (bitumen) & sand. Aggregates used for the asphalt mix could be crushed rock, sand and gravel, or slags.
Whereas Bitumen is actually the liquid binder that holds the asphalt together. The term bitumen is often mistakenly used to the describe asphalt.
Asphalt is widely used for the constructing & maintaining all types of the roads be it for highways, inner-city & inter-city roads, local roads and car parks, or paving driveways & pavements. I will briefly discuss the difference between asphalt & bitumen in the another article.
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
= 5000 x Six x 0.15 = 4500 m^{3}
Here, the density of the asphalt is taken as 2330 kg/m^{3}
Therefore, Quantity of the asphalt = Volume of the asphalt x Density of the asphalt
= 4500 x 2330 = 10485000 kg = 10485 tons.
Suppose the cost of One ton asphalt is 6000 rs.
Cost of the asphalt = 10485 x 6000 = 62910000 rs.
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 curved road = Length x Width x Thickness
= L x W x H = 17.44 x Six x 0.15 = 15.696 m^{3}
= 15.69 x 2330 = 36558 kg = 36.55 tons.
Suppose the cost of One ton asphalt is 6000 rs.
Cost of the asphalt = 36.55 x 6000 = 219300 rs
In case of the area u are calculating has an irregular shape, divide it into the several regularly-shaped sections, then Calculate each of their volume & asphalt requirements using the above method. Finally sum them the up together.
