 |
Road marking is any kind of device or material that is used on a road surface in order to convey official information. They can also be applied in other facilities used by vehicles to mark parking spaces or designate areas for other uses.
Road markings are used on paved roadways to provide guidance and information to drivers and pedestrians. Uniformity of the markings is an important factor in minimizing confusion and uncertainty about their meaning, and efforts exist to standardize such markings across borders.
They can be used to delineate traffic lanes, inform motorists and pedestrians or serve as noise generators when run across a road, or attempt to wake a sleeping driver when installed in the shoulders of a road. Road marking can also indicate regulation for parking and stopping.
There is continuous effort by us to improve the road marking system, and technological breakthroughs include adding reflectivity, increasing longevity, and lowering installation cost. |

| Procedure |
SURFACE PREPARATION
- Asphalt surface preparation must be dry, free from dust, dirt, grease and loose materials.
- Concrete surface must be dry, clean, free from laitance and dust.
- Concrete surface previously treated wih curing compound must be treated with a concrete primer sealer before application.
METHOD OF APPLICATION
Thermoplastic markings are applied using specially designed vehicles. The thermoplastic mix is heated in trucks to about 200 °C (400 °F) before being fed to the application apparatus. This is often a screed box or ribbon gun. Immediately after the thermoplastic has been applied, glass beads are laid onto the hot material so that they embed before the plastic hardens. These beads provide initial retro-reflection. As the marking wears during use and the initial beads are lost, the beads mixed with the binder are uncovered, providing long term reflectivity. Most thermoplastic is produced in white and yellow colors, but other colors such as red may also be produced.
