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.
Additional Topics Discussed
- Classification of pavement marking
- Markings related to speed reduction, pedestrian crossings, and cyclist considerations
- Importance of markings in parking areas
- Role of road studs and at-grade intersection markings
- Performance assessment and monitoring mechanisms for road marking materials.
