How is material quantity of a road calculated?
The asphalt quantity can be calculated by simply multiplying length, width and thickness. The thickness can vary depending on the previous layer profile. Hence it is imperative to make sure a survey check is done before, during and after each of the above mentioned activity.
How do you calculate aggregate and bitumen quantity for a road?
How Much Bitumen Used in Road Construction Per Kilometre?
- Find out the dimension (Width and thickness)
- Calculate Volume of Asphalt = (Long * Width * Thickness) m^3.
- Find out the density of Asphalt (2330 or 2450 Kg/m^3)
- Calculate the quantity of Asphalt= ( Density* Volume) Kg/MTon.
How do you calculate asphalt for a road?
Quantity Calculation: = 2400 x 2330 = 559200kg = 5592 tons (dividing by 1000).
How is earthwork quantity calculated?
Volume = Sum * 100 (Area of Each block) = 4.6225 * 100 = 462.25 (Filling).
How is road work measured?
The lane kilometer method involves measuring the length of each new lane that is built instead of counting the overall length of the highway. For instance, one km of a four lane highway will be counted as four km under the method. “This is a more realistic assessment of the total length that has been constructed.
How is road base calculated?
Manual Calculator
- Multiply the length of the area by the width of the area = Square Feet.
- Multiply Square Feet by the Depth* = Cubic Feet.
- Divide Cubic Feet by 27 = Cubic Yards.
- Multiply Cubic Yards by 1.5 = Tons Needed.
What is the method used for calculation of earthwork in road estimation?
Following methods are used in the calculation of earthwork: Prismoidal method. Trapezoidal method. Midsection area method. mean section area method.
How is road excavation volume calculated?
How do you calculate earthwork quantity?
The determination of earthwork quantities is based upon field cross- sections taken in a specified manner before and after excavation. Cross- sections are vertical profiles taken at right angles to the survey centerline. Every section is an area formed by the subgrade, the sideslopes, and the original ground surface.
How do you calculate the quantity of materials needed for concrete?
The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg. Weight of coarse aggregate = 3 x 364.5 = 1093.5 kg. Concrete Calculator: Calculate Quantities of Materials for Concrete
How to calculate the quantity of asphalt in a road?
Therefore, quantity of asphalt = volume of road section x density of asphalt = 2400 x 2330 = 559200kg = 5592 tons (dividing by 1000).
How to calculate the quantities of road construction work?
For calculating the quantities we should have the sectional cross-section of the road which will detail the pavement layers with thickness and the area of the road. This is prerequisite. The road works encompasses a plethora of activties.
How do Engineers estimate the life of a road pavement?
Road engineers estimate the pavement damage from the axle loads of the various vehicles expected to use the pavement over its designed life, usually 20 years. As a general principle, the heavier and more numerous the vehicles using the road, the thicker the pavement needed to support them.
