Study Notes

Road Markings Overview

Road markings are lines, patterns, or words applied to the roadway to control, warn, guide, and inform road users.
They serve as psychological barriers, delineating traffic paths and facilitating safe movement away from hazards.

Types of Road Marking Materials

Thermoplastic Markings
- Popular due to durability; a blend of plasticizer and resins that adheres upon solidifying.
- Fast drying and commonly used in high-traffic areas.
- Service life ranges between 2 to 3 years, influenced by traffic volumes.
Solventborne and Waterborne Road Marking Paints
- Solvent-based and water-based are the two primary types.
- Water-based paints are environmentally friendly, easier to handle, and pose fewer safety risks.
- Water-based markings allow quicker reopening of roads to traffic compared to solvent-based paints.
Cold Applied Plastics
- Offers superior durability in retaining color and luminance.
- Can be applied in various methods, requires less equipment, and is portable.
Preformed Adhesive Tapes
- Available in various lengths and widths; provides a service life of 3 to 6 months.
- Higher initial cost but suitable for high traffic areas requiring frequent replacements.

Colour Patterns for Markings

White
- Widely used due to visibility and contrast against the road surface.
Yellow
- Indicates areas where crossing is not permitted through longitudinal marking.
Blue
- Designated for new and special markings that differ from traditional designations.
Green
- Used to mark paths for bicycles and non-motorized transport.
Red
- Indicates shared spaces for multiple road users, particularly in non-hazardous areas.

Code of Practice

The document IRC:35-2015, established by the Indian Road Congress, provides guidelines on uniform road marking systems in India.
It covers various aspects including classification, application methods, and performance monitoring of road markings.
