Road noise is a common issue in urban and residential areas, affecting both comfort and quality of life. While traffic volume and vehicle types contribute to noise pollution, the choice of road surfacing plays a significant role in minimising sound levels. Asphalt has proven to be an effective solution for noise reduction, providing quieter roads and driveways. For property owners, councils, and developers in Mount Barker, SA, understanding the benefits of asphalt in noise control can help improve infrastructure planning and community well-being.
1. How Asphalt Reduces Road Noise
Asphalt surfaces are engineered to absorb sound and reduce noise generated by vehicle tyres. Unlike rigid surfaces such as concrete, asphalt has a flexible structure that minimises sound reflection and dampens vibrations.
- Sound Absorption: Open-graded asphalt mixes have air voids that trap and disperse noise.
- Smooth Surface Texture: Reduces tyre friction and road noise compared to rougher surfaces.
2. The Impact of Road Noise on Communities
Excessive road noise can affect residents, businesses, and overall urban liveability. High noise levels have been linked to:
- Reduced Property Value: Areas with persistent road noise may experience lower demand.
- Health and Well-being Issues: Prolonged exposure to road noise can lead to stress and sleep disturbances.
- Disruptions to Commercial Spaces: Loud environments can impact retail and office productivity.
3. Types of Asphalt for Noise Reduction
Different asphalt formulations are designed to enhance noise reduction while maintaining durability and performance.
- Open-Graded Asphalt: Features a porous structure that absorbs sound and improves drainage.
- Rubberised Asphalt: Contains recycled rubber to enhance flexibility and noise-dampening properties.
- Stone Mastic Asphalt (SMA): Provides a dense and textured surface that reduces tyre-generated noise.
4. Benefits of Using Asphalt for Driveways and Residential Areas
Homeowners and developers looking to reduce noise impact on private properties can benefit from asphalt surfacing for driveways, pathways, and shared roadways.
- Quieter Traffic Movement: Ideal for driveways and residential streets where low noise levels are preferred.
- Enhanced Comfort: Reduces sound impact on surrounding homes and outdoor spaces.
- Aesthetic and Functional: Provides a sleek, smooth finish that complements residential landscapes.
5. Why Asphalt Is a Preferred Choice for Urban Road Construction
Many councils and infrastructure planners are choosing asphalt over other materials due to its noise-reducing properties and long-term benefits.
- Cost-Effective Solution: Asphalt is more affordable than concrete and offers lower maintenance costs.
- Sustainability Benefits: Recycled asphalt reduces environmental impact while maintaining quality.
- Faster Installation: Roads can be resurfaced quickly with minimal disruptions to traffic flow.
