Detailed Standards Coverage

SIST EN 12697-49:2014 - Determination of Friction After Polishing

Bituminous mixtures – Test methods for hot mix asphalt – Part 49: Determination of friction after polishing

Modern roads are exposed to constant vehicle loads, climatic conditions, and wear from regular traffic. Surface friction plays an essential role in preventing skidding, especially in hazardous conditions. SIST EN 12697-49:2014 specifies a precisely controlled laboratory test to measure the friction performance of asphalt surfaces after a set number of polishing cycles, simulating real-life wear conditions. This approach allows engineers to compare surfacing materials and select the best-performing options for public safety.

What the Standard Covers and Its Scope

• Describes laboratory and in-situ test methods for assessing friction at 60 km/h after the surface of a bituminous mixture sample is artificially polished
• Applicable to hot mix asphalt samples either produced in the lab or extracted from road cores
• Harmonizes testing as per the previous Wehner and Schulze method, fostering cross-border comparability

Key Requirements and Procedures

• Polishing Process: Uses a test apparatus with a controlled polishing head; the sample undergoes a set number of passes with abrasive media under standardized conditions
• Friction Measurement: Post-polishing, friction is measured dynamically at a test speed of 60 km/h
• Sample Preparation: Can be undertaken with field cores or lab-cast specimens, ensuring adaptability to project needs
• Calculation: Results yield a friction after polishing (FAP) value—a crucial indicator for expected skid resistance in service

Target Audience and Applications

• Civil engineering labs, road authorities, construction contractors, and quality reviewers
• Projects involving highway design, urban roads, motorways, and airport runways

Practical Implications

• Enhances selection of aggregates and binders for long-term skid resistance and durability
• Allows routine testing to monitor road surface performance and schedule timely maintenance
• Supports accident reduction strategies through evidence-based surfacing choices

Key highlights:

• Simulate real-world surface wear, ensuring relevant safety assessments
• Consistent, repeatable friction values that underpin safe road design
• Suits both laboratory and on-site testing for flexible quality control

SIST EN 1436:2007 - Road Marking Performance for Road Users

Road marking materials – Road marking performance for road users

Road markings are vital for traffic navigation, lane discipline, and pedestrian safety. They must remain visible under various lighting and weather conditions and retain their effectiveness over time. SIST EN 1436:2007 sets out comprehensive performance criteria for road markings, focusing on their daytime and nighttime visibility, color consistency, and skid resistance. By specifying measurable performance classes, the standard ensures that road markings serve all users—drivers, cyclists, and pedestrians—effectively throughout their functional life.

What the Standard Covers and Its Scope

• Specifies requirements for white and yellow road markings (paints, thermoplastic materials, cold plastics, etc.)
• Focuses on reflection (in daylight, under road lighting, and in vehicle headlights), color, and skid resistance measured under wet and dry conditions
• Applies to both permanent and temporary markings on asphalt and concrete surfaces

Key Requirements and Specifications

• Visibility: Defines luminance coefficient under diffuse illumination (Qd) and luminance factor (β) for daytime brightness
• Retroreflectivity: Sets minimum retroreflected luminance (RL) for safe nighttime visibility
• Color: Requires markings to meet specific chromaticity coordinates, ensuring they are distinguishable to all road users
• Skid Resistance: Stipulates SRT (Skid Resistance Tester) values, reducing slip risks in wet conditions
• Performance Classes: Multiple performance classes for each parameter, enabling tailored specifications per road category and environment

Who Needs to Comply

• Highways agencies, road contractors, marking material suppliers, city and regional traffic authorities
• Any organization responsible for road infrastructure safety and maintenance

Practical Implications for Implementation

• Enables performance-based procurement of road marking materials
• Facilitates monitoring and timely renewal or repair of road markings
• Ensures markings are optimized for visibility in diverse climates and for special situations (e.g., rain, fog)

Key highlights:

• Codified measurement for both dry and wet conditions, simulating real-world scenarios
• Ensures all marking systems meet rigorous color and reflectivity standards
• Directly contributes to accident prevention and road user safety

Industry Impact & Compliance

Why do standards like SIST EN 12697-49:2014 and SIST EN 1436:2007 matter for businesses and authorities?

• Regulatory Assurance: Adopting these standards assures compliance with European and global best practices, reducing regulatory risk and liability.
• Benchmarking Performance: Standardized testing and classification enable fair comparison, quality assurance, and consistent tendering for public projects.
• Road Safety: Both standards directly target accident reduction—friction to prevent skidding, markings to guide users clearly in all visibility conditions.
• Public Trust and Transparency: Clearly defined performance classes facilitate communication with stakeholders and public agencies.

Compliance Considerations

• Legal or contractual compliance is routine in EU infrastructure projects and increasingly recognized worldwide
• Failure to comply can result in costly rework, legal disputes, accident liability, and project delays

Benefits of Adopting These Standards

• Productivity: Standardized methods speed up decision-making, quality control, and project scaling
• Security: Direct focus on safety and risk reduction, protecting users and companies alike
• Scaling: Harmonization ensures that large infrastructure projects can be confidently executed across regions and borders

Risks of Non-Compliance

• Potential for premature surface failure, increasing maintenance costs
• Higher accident rates due to inadequate surface friction or poor visibility
• Ineligibility for public contracts or funding

Implementation Guidance

Implementing road materials standards may seem daunting, but a structured approach leads to measurable improvements:

Common Implementation Approaches

1. Staff Training: Ensure laboratory and field teams are familiar with test procedures and requirements
2. Equipment Investment: Acquire or calibrate necessary test instruments for friction, retroreflectivity, and color measurement
3. Material Selection: Use specifications to select or design asphalt mixes and marking products that meet or exceed required classes
4. Quality Assurance: Set up routine sample testing from both laboratory batches and field sites
5. Documentation: Maintain detailed test reports and compliance certificates for transparency and audit purposes
6. Continuous Improvement: Analyze failures or periodic performance reviews to inform surfacing and marking upgrades

Best Practices for Effective Adoption
