What is Earth Road & Gravel Road?

Earth Road

An earth road is the cheapest type of road prepared from natural soil. The pavement section is totally made out of locally available soil. These roads require very steep camber ranging between 1 in 25 and 1 in 33 to drain off the rain water quickly from the pavement surface.

These roads are generally constructed with ordinary soil or stabilized soil. In our country, these roads are roads constructed as village roads.

Gravel Road

Gravel roads are constructed with one or two compacted layers of gravel mixed with sand and clay. The camber may be between 1 in 25 and 1 in 30. These roads are considered better than the earth roads as they can carry heavier traffic. These roads are considered low-cost roads. These roads are generally constructed as village roads and other district roads.
