This activity includes removing or stripping off the upper soil layer(s) from the natural ground. All organic materials, topsoil, and stones greater than 3 inches in size should be removed.
Gravel roads are considered superior to earth roads. Camber is provided 1 in 25 and 1 in 30. Gravel roads may be constructed in form of trench type or feather edges type patterns. The depth of the trench is dependent upon the thickness of the gravel pavement to be provided. Maximum size of 12.5mm to 20mm.

3. Construction of Gravel Roads a. Alignment Selection. The alignment shows the path through which the road will pass. So, the selection of road alignment should be done such that it has less conflict, high soil strength & shorter length. Road alignment is the key factor that directly influences the construction speed and economy. b.
Roads. Although there were highway links in Mesopotamia from as early as 3500 bc, the Romans were probably the first roadbuilders with fixed engineering standards. At the peak of the Roman Empire in the first
