The width of the embankment top layer can be calculated using trigonometry.

• Use trigonometry to calculate the width of the embankment top layer.

• The width can be calculated using the formula: width = 2 * height * tan(angle)

• In this case, the angle is the angle of repose (ogl) which is typically around 30-45 degrees.

WMM stands for Wet Mix Macadam, which is a type of road construction material.

• WMM is a mixture of aggregates, water, and binding materials.

• It is used as a base or sub-base layer in road construction.

• WMM provides better strength and durability compared to conventional macadam.

• It is designed to withstand heavy traffic loads and adverse weather conditions.

• Examples of binding materials used in WMM include cement, lime, or bitumen.

GSB stands for Granular Sub-Base, which is a layer of compacted material used in road construction.

• GSB is a layer of material placed between the subgrade and the base course of a road.

• It provides a stable foundation for the road and helps in distributing the load from the traffic.

• The material used in GSB can vary, but it is typically a mixture of crushed stone, gravel, and sand.
