Earth roads are of the following two types:-

1) Ordinary earth roads :- The earth road having its foundation and wearing surface consisting of one or two compacted layers of natural soil available along its alignment is called an ordinary earth road.
This is the lowest form of pavement surface used so far and is considered as the first stage in the development of road pavement construction. The surface of these roads is generally dusty and ruts are quickly formed. These roads become unserviceable very soon an thus require frequent repair in order to keep them in serviceable condition for a longer period.

2) Stabilized earth roads :- The earth road having its foundation and wearing surface consisting of one or two compacted layers of stabilized soil is called stabilized-earth road.
This is the improved form of earth roads. These roads can carry greater traffic, load and provide better better service as compared to ordinary earth roads.
