How to compute asphalt in road highways in hill areas

Construction Software

In this construction tutorial video, one can learn in detail how to work out asphalt in highways located at hill areas.

In this video a solution is given to the following problem :-

Problem : Compute asphalt in tons for a specified highway. The breadth of the highway is given as 8 meter, the thickness of the asphalt is given as 15 cm and its chainage is approx. 7+10 KM (Chainage stands for a fictional line that is utilized to workout distance, usually appear as the centre of a straight road). The density of the asphalt to be used is 2400 kg/cu.m.

Solution :

Weight of asphalt = Volume x Density of asphalt

Volume is determined by using the following formula :-

V = Length x Breadth x Thickness

= {(7x1000)+100} x 8 x 0.15 (Here, kilometer is converted to meter and centimeter is converted to meter)
= 7100 x 8 x 0.15
= 8520 m3

So, weight of asphalt = Volume x Density of asphalt = 8520 x 2400 = 20448000 kg/1000 (Convert it to ton) = 20448 Tons
