LS-68A IIRPM: Internally Illuminated Raised Pavement Markers Built to Class F ASTM E4280 Standards

In today’s road safety environment, visibility is everything—especially in low-light, wet, or hazardous conditions. That’s where IIRPM (Internally Illuminated Raised Pavement Markers) come in, offering constant active guidance when traditional reflective markers fail. Among the best in class is Lubao’s LS-68A, a high-performance IIRPM designed to meet and exceed ASTM E4280 Class F conditions.

What is an IIRPM?

An Internally Illuminated Raised Pavement Marker is a solar-powered, surface-mounted device equipped with active LED lighting. Unlike passive reflective markers, IIRPMs remain clearly visible in fog, rain, and complete darkness—making them essential for critical safety zones, curves, tunnels, and diversion routes.

LS-68A – Engineered for Demanding Roadway Conditions

Lubao’s LS-68A is purpose-built for highway-grade durability, intense visibility, and long-term operation. It is compliant with the ASTM E4280 Class F standard, which is the highest performance class under this international guideline for IIRPMs.

Key Features of LS-68A IIRPM

• Active LED Illumination: Dual-sided LED lights (up to 6 LEDs total), available in white, red, yellow, blue, or green. Configurable in flashing or steady lighting modes.
• Solar Powered: High-efficiency solar panel with rechargeable lithium battery. Delivers 120+ hours of working time per full charge.
• Heavy-Duty Body: Made from die-cast aluminum alloy and polycarbonate lens, withstanding loads over 30 tons—ideal for highways and airport taxiways.
• Fully Embedded Design: Flush to road surface for snowplow resistance, stable bonding, and minimal vibration.
• IP68 Waterproof: Guaranteed performance in heavy rain, snow, or submerged conditions.
• Extreme Temperature Resistance: Operates reliably from -40°C to +70°C in diverse climates.

Class F ASTM E4280 Compliance – What It Means?

ASTM E4280 defines performance for Internally Illuminated Raised Pavement Markers. The Class F category is the highest rating, intended for the most demanding road applications such as highways, tunnels, bridges, and high-traffic zones.

Class F Key Requirements?:

• Active Illumination: LEDs must be clearly visible at night, even without vehicle headlights.
• Wet-Night Visibility: Maintains brightness in rain, fog, and wet road surfaces.
• Load Resistance: Withstands minimum 13,500 kg (~30 tons) of compressive force.
• Ingress Protection: IP68 waterproof rating or better; tested under immersion and high-pressure washing.
• Long-Term Performance: Remains functional after UV, corrosion, and thermal cycling tests.
• Wide Temperature Range: Operates reliably between -40°C and +70°C.
• Mounting Security: Embedded or surface-fixed designs must resist snowplows and vibration.
• Low Maintenance: Long-lasting battery and LED life span, with minimal need for servicing.

✅ LS-68A’s Compliance with Class F

The LS-68A meets or exceeds all of the above Class F criteria. It has undergone rigorous testing and real-world validation to confirm performance under harsh conditions. It is a trusted solution for agencies requiring certified IIRPMs that deliver reliable visibility and long service life.
