- There are two types of marking: water paint marking for temporary diversion and thermoplastic road marking for permanent marking.
- Before starting the thermoplastic marking, a surveyor must do the setting out or free marking.
- Pre-marking must be done for each line, and the area should be cleaned properly.
- The road marking material is heated in a furnace to 250°C before being put in a smaller machine for use.
- Glass beads are also spread over the marking for reflective purposes.
- The center line marking size depends on traffic flow and is used to facilitate traffic movement.
- Breakup lines allow for easy diversion from one line to another.


The video is a tutorial on how to apply thermoplastic road marking, which is a permanent road marking applied over the wearing course. Before starting the marking, the surveyor must do the setting out or free marking, which should be approved by the surveyors. Once the pre-marking is approved, it should be done for each and every line. The road marking material is heated in a furnace to a required temperature of 250° centigrade before it is put into the smaller machine used for the road marking. Glass beads are added to the material for reflective purposes. The thermoplastic material is then applied using a machine, and the glass beads are spread automatically over the hard thermoplastic marking. The line marking should facilitate traffic to draw in a specific way, and if there is a break-up in the center line, traffic can divert from one line to another line easily. The video shows how the road marking is applied to a three-lane carriageway.
