What is a Cold Milling Machine? Overview and Working Principles
Cold milling machines are specialized equipment used in road construction to remove asphalt and concrete surfaces efficiently and precisely. These machines employ a rotating drum equipped with cutting teeth that grind and mill the surface, allowing for recycling and resurfacing without damaging the underlying layers.
Cold milling is a cost-effective, eco-friendly alternative to traditional demolition methods. It enables the removal of worn-out pavement while minimizing dust, noise, and vibration, making it ideal for urban environments. The milled material, known as reclaimed asphalt pavement (RAP), can be reused in new asphalt mixes, promoting sustainability.
Cold milling machines vary in size and capability, from compact units for small projects to large, high-capacity models for highways and airports. Their precision controls allow operators to set milling depth and width accurately, ensuring smooth and even road surfaces ready for repaving.
