LoNoise™ asphalt is a thin hot-mix surfacing designed to reduce traffic noise on heavily trafficked urban and suburban roads. Originating in France in 1994, LoNoise™ has been successfully trialled and applied in Australia by Boral. Its unique mix design incorporates recycled rubber granules, delivering quieter roads and improved sustainability.
Features and Benefits

LoNoise™ vs Standard Asphalt
| Feature | LoNoise™ Asphalt | Standard Asphalt |
| Noise Reduction | LoNoise™ reduces tyre-road noise by several decibels, improving community comfort. | Standard asphalt does not provide noise-reducing properties. |
| Recycled Tyre Content | Uses recycled rubber granules, diverting waste from landfill and supporting sustainability goals. | Does not include recycled tyre material, offering no environmental benefit in this area. |
| Rut Resistance | Provides good deformation resistance, suitable for high-volume traffic corridors. | Standard asphalt offers general durability but may require more frequent maintenance under heavy loads. |
Frequently Asked Questions
1. How much noise reduction does LoNoise™ asphalt provide?
LoNoise™ asphalt can reduce tyre-road noise by several decibels compared to conventional asphalt, improving comfort for nearby residents.
2. Is LoNoise™ asphalt suitable for all road types?
It is ideal for urban roads, residential streets, and high-volume traffic corridors. It is not typically used for low-traffic rural roads.
3. Does LoNoise™ asphalt require special equipment?
No. LoNoise™ can be laid using standard asphalt paving equipment, making it easy to integrate into existing road construction processes.
4. How sustainable is LoNoise™ asphalt?
Each square metre of LoNoise™ asphalt incorporates approximately half a recycled tyre, reducing landfill waste and supporting circular economy goals.
