RoadvisionAI strengthens national highway compliance by aligning digital inspections with IRC 35 2015 standards. Through AI pavement inspection, authorities can monitor marking performance and maintain uniformity across expanding transport networks.
India’s road markings may appear simple, but they guide traffic flow, prevent confusion, and save lives every day. As traffic volumes increase, irc 35 2015 plays a critical role in standardising marking types, materials, and applications across the country.
As the proverb says, “A stitch in time saves nine.” Clear and well-maintained road markings prevent accidents before they happen.
Officially known as the Code of Practice for Road Markings, IRC Code 35 was first introduced in 1970 and comprehensively revised as IRC 35 2015.
The code ensures that road markings remain:
Road markings function as:
On high-speed highways and dense urban corridors, they are indispensable.
IRC Code 35 recommends materials based on durability, traffic intensity, and expected service life.
Thermoplastic markings are the most widely used permanent solution in India.
Key Features
Best Applications
Monitoring installation quality can be improved using AI construction monitoring systems.
Paint-based systems are generally used for temporary or low-volume roads.
Advantages
Limitation
Cold-applied plastics offer high durability without requiring heating.
Ideal For
Factory-manufactured tapes applied directly to pavement surfaces.
Benefits
Colours under irc 35 2015 carry specific regulatory meaning.
Standardised colour usage ensures predictability nationwide.
IRC Code 35 groups pavement markings into seven categories.
Run parallel to traffic flow.
Examples:
Placed across the roadway, mainly at intersections.
Examples:
Warn drivers of potential risks.
Examples:
Highlight specific safety zones such as zebra crossings and school areas.
Indicate permitted vehicle movements before intersections.
Text-based markings such as STOP and SLOW that reinforce roadside signage.
Define special-purpose infrastructure including:
These categories support structured traffic engineering practices across India.
Visibility is a core requirement under IRC 35 2015.
Markings must remain visible long enough to allow at least two seconds of driver reaction time at operating speed.
Embedded glass beads enhance night-time performance. They:
Field validation using automated pavement distress detection ensures reflectivity levels remain within safe limits.
Road studs complement pavement markings, especially in low-light conditions.
Correct placement improves durability and consistent guidance.
IRC Code 35 emphasises regular inspection of:
Digital documentation through Enterprise DMS & Workflow Agent strengthens compliance reporting and audit transparency.
When visibility drops below required thresholds, repainting or reapplication becomes necessary.
Implementing irc 35 2015 is not merely about compliance. It is about building predictable, readable, and reliable road environments that enhance national safety standards.
By integrating AI roadway inspection with structured monitoring systems, agencies can proactively maintain marking quality and extend pavement life cycles.
Every marking type, colour selection, and material choice contributes to safer mobility. Road markings are truly the silent sentinels of India’s transport network.
Q1. What types of road markings are covered under IRC Code 35?
IRC Code 35 includes longitudinal, transverse, hazard, block, arrow, directional, and facility markings along with approved marking materials.
Q2. Which marking material is most durable for Indian highways?
Thermoplastic road markings are widely considered the most durable due to strong adhesion and long-lasting retroreflective performance.
Q3. How do road markings improve road safety?
High-visibility pavement markings enhance lane discipline, provide night guidance, reduce confusion, and lower accident risks across urban and rural roads.
