• Why material properties and marking performance matter for everyday use
• What businesses need to know for compliance and quality assurance
• Tips for effective standard implementation in construction projects

Whether you’re a civil engineer, a procurement specialist, or simply interested in how safer, longer-lasting roads are built, this guide demystifies the essential standards governing road construction materials today.

Detailed Standards Coverage

SIST EN 12697-49:2014 — Friction After Polishing for Hot Mix Asphalt

Bituminous Mixtures – Test Methods for Hot Mix Asphalt – Part 49: Determination of Friction After Polishing

This standard outlines a laboratory test method for determining the friction level of bituminous mixtures after a controlled polishing process, simulating the wear and tear of real traffic. Friction at 60 km/h is measured after the surface undergoes a fixed number of polishing cycles, providing a vital indication of skid resistance and, thus, road safety under typical driving conditions.

The scope covers both asphalt samples produced in the lab and cores extracted from real road sites. Known as the "Wehner and Schulze method," it uses specialized equipment to replicate wheel passes and precisely measure resulting surface friction.

For road construction contractors, highway authorities, and materials laboratories, compliance ensures asphalt surfaces retain grip even after use — helping to reduce accident risks, particularly in wet or high-traffic conditions.

Notable requirements include:

• Strict use of calibrated test devices for reliability and repeatability
• Detailed specimen preparation, whether laboratory-mixed or site-extracted
• Comprehensive documentation of test conditions and results

Key highlights:

• Simulates real-world polishing to assess long-term performance
• Critical for safety evaluation of new and existing asphalts
• Provides data for material selection, mix design, and surface maintenance

SIST EN 1423:1999 — Drop On Materials for Road Markings

Road Marking Materials – Drop On Materials – Glass Beads, Antiskid Aggregates, and Mixtures

SIST EN 1423:1999 sets the requirements for "drop-on" materials — the glass beads, antiskid aggregates, or their mixtures that are sprinkled onto freshly applied line markings. These drop-on components dramatically enhance road marking visibility at night (via retroreflection from beads) and friction (thanks to antiskid particles), directly influencing both the safety and durability of markings.

The standard defines product control tests and qualification criteria for these additives, covering their use on various marking systems such as paints, cold plastics, and thermoplastics. Key focus areas include grading, roundness, refractive index (for glass beads), and non-aggregation in storage and use.

Compliance is essential for any manufacturer, supplier, or contractor involved in road marking application — especially on roads demanding superior nighttime visibility or anti-slip performance.

Key highlights:

• Lab-based procedures for verifying optics and antiskid properties
• Suitability across a range of marking materials
• Ensures consistent road marking performance through product control tests

SIST EN 1436:2007 — Performance of Road Markings for Users

Road Marking Materials – Road Marking Performance for Road Users

SIST EN 1436:2007 is the benchmark for evaluating the in-use performance of white and yellow road markings. It stipulates how to assess reflection under both daylight and vehicle headlamp illumination (i.e., retroreflection), chromaticity (color), and essential safety factors such as skid resistance.

It defines classes for minimum luminance, retroreflection, and SRT (skid resistance tester value), making it the reference for tendering, material selection, and regulatory compliance across Europe. Whether a marking is permanent or temporary, type I or enhanced type II (wet performance), the standard ensures it meets visibility and safety criteria drivers expect — no matter the weather.

Authorities and private contractors alike rely on SIST EN 1436 to specify performance classes suited to national or local requirements, ensuring all new road markings support safe navigation day and night.

Key highlights:

• Strict thresholds for brightness, retroreflective performance, and color
• Includes anti-skid requirements and wet condition performance
• Harmonized classes support public safety and procurement decisions

SIST EN 1871:2002 — Physical Properties of Road Marking Materials

Road Marking Materials – Physical Properties

This standard specifies laboratory test methods and requirements for the physical properties of both permanent and temporary road marking materials. It covers paints, thermoplastics, cold plastics, and other types — whether or not they include retroreflective elements.

By defining how to test for abrasion resistance, color retention, bead embedment, softening points, and flow resistance, SIST EN 1871 underpins the durability and functionality of any road marking — before application and throughout its life cycle in service.

Producers, quality assurance laboratories, and end users rely on this standard to guarantee their road markings stand up to weather, UV, de-icing salts, mechanical wear, and cleaning routines.

Key highlights:

• Defines baseline physical performance before and after application
• Important for both new installations and ongoing maintenance
• Ensures compatibility with requirements set in SIST EN 1436
