BS 3262 Thermoplastic Road Marking Paints Compliant with British Standards for Durability and Reflectivity
Product Description
The BS 3262 standard, issued by the British Standards Institution (BSI), outlines the composition, performance, and application of thermoplastic paints primarily for white and yellow road markings. It applies to materials melted and applied hot via screeding or spraying, forming thin superimposed layers on road surfaces (not inset materials). The standard ensures durability, reflectivity, and safety for road markings under various traffic and environmental conditions.
Parts of BS 3262
- Part 1: Specification for Constituent Materials and Mixtures
- Defines the raw materials and their proportions, including:
- Resin Binder: Typically petroleum resin (minimum 18%) or aliphatic hydrocarbon resin plasticized with mineral oil to hold the mixture together.
- Pigments: Titanium dioxide (typically 12%) for whiteness or yellowness.
- Glass Beads: Minimum 20% premixed for retro-reflectivity (night visibility), compliant with standards like BS 6088 Class A or EN 1424.
- Aggregates and Extenders: Light-colored silica sand or other fillers for bulk.
-
- Ensures the material’s chemical and physical properties meet quality standards.
-
- Part 2: Specification for Road Performance
- Outlines performance requirements for type-approved white thermoplastic materials, with provisions for yellow and black materials if their composition (except pigment) matches the white material.
- Key performance criteria:
- Durability: Must withstand heavy traffic and environmental conditions (e.g., UV radiation, rain, snow, temperature fluctuations).
- Retro-reflectivity: Enhanced by glass beads for night visibility, tested per standards like BS EN 1436.
- Skid Resistance: Adjustable anti-slip formulas for safety.
- Adhesion: Strong bonding to asphalt and concrete surfaces to prevent peeling or cracking.
-
- Includes testing protocols, such as a two-year performance trial on a designated site (e.g., A1 at St. Neots), to ensure long-term quality.
-
- Part 3: Specification for Application of Material to Road Surfaces
- Details the application process, including:
- Heating: Material is heated to 180–220°C to achieve fluidity.
- Application Methods: Screeding, spraying, or extrusion using specialized hot-melt equipment.
- Curing Time: Rapid solidification (2–5 minutes) upon cooling, allowing quick reopening of roads.
-
- Emphasizes quality workmanship to ensure durability and performance.
-
Application of Thermoplastic Paint:
-
- Surface Prep:
- Clean, dry road surface (asphalt/concrete), free of oil/dust.
- Primer for concrete or worn asphalt if needed.
- No application in rain, >85% humidity, or <5°C.
-
- Heating:
- Melt at 180–220°C in a pre-heater.
- Avoid overheating (>230°C) to prevent degradation.
-
- Application Methods:
- Screed: 2.5–3 mm for lines, arrows, text.
- Spray: 1.5–2 mm for large areas.
- Extrusion: 3–6 mm for profiled markings.
- Manual: For small areas or symbols.
-
- Glass Beads:
- Drop-on: 250–400 g/m², 80% surface coverage.
- Premixed: ≥20% for reflectivity (100 mcd/m²/lx for white).
-
- Thickness:
- Flat: 1.5–3 mm.
- Profiled: Up to 6 mm.
-
- Curing:
- Sets in 2–5 minutes at 15–25°C.
- No tackiness or tracking post-curing.
-
ApplicationsBS 3262 thermoplastic paint is used for:- Highways and Expressways: High-traffic roads requiring durable, reflective markings.
- Urban Roads: City streets, crosswalks, bus lanes, and intersections.
- Airports: Runway and taxiway markings with high reflectivity and abrasion resistance.
- Parking Lots: Line markings for parking spaces and directional arrows.
- Cycle Tracks and Pedestrian Walkways: Colored surfacing for designated areas.
