bitumen road layers thickness

Why thickness measurement in road construction is essential for the

The layer thicknesses stagger depending on the material and type of the road between 5cm - 12cm. III. Top layer The top layer is the most heavily used layer of the road, because it is subject to the direct influence of traffic, weather and thawing agents. Thus, the top layer must be particularly resistant to wear and deformation.

How to Calculate Asphalt or Bitumen Quantity for Road in Tons

2022/2/19 · Here, the Density of Asphalt is taken as 2400 kg/m3. The Quantity of Asphalt = Volume of Asphalt x Density of Asphalt. The Quantity of Asphalt = 18000 x 2400 = 43200000 Kg. Quantity of Asphalt in Tons = Quantity of Asphalt / 1000. Quantity of Asphalt for Road in Tons = 43200000 / 1000 = 432000 Tons.
