Surface coating is a process that involves covering the road surface with asphalt emulsion and gravel to make it more durable and even. The surface coating may be single-layer or multi-layer. In single-layer surface coating, asphalt emulsion and gravel are laid once. In multi-layer surface coating, asphalt emulsion and gravel are applied multiple times to achieve a higher quality surface.

The advantages of surface coating are as follows:

• It is quick and economical to build.
• The road may be opened to traffic shortly.
• The slip resistance is high.
• It allows for phased construction.
• It cuts through the dust and dirt on the road surface.

The surface coating application consists of the following stages:

• The road surface is cleaned.
• Asphalt emulsion is sprayed onto the base material.
• Gravel is spread and rolled.
• In multi-layer surface coating, asphalt emulsion is sprayed again, gravel is spread again and rolled.
