Introduction

Milling machines are a crucial component in road construction and maintenance, used to remove old pavement surfaces, level roadways, and prepare them for repaving. Their utilization helps in achieving efficient, durable, and cost-effective road infrastructure.

Purpose of a Milling Machine on Roads

The primary purpose of a milling machine, also known as a cold planer, at construction sites is to remove the deteriorated layers of roads. This removal serves several functions:

• Surface Preparation: Milling machines prepare the road surface for new asphalt or concrete by removing old and damaged layers.
• Depth Control: These machines can precisely control the depth of milling, allowing for accurate removal of road layers to the desired specifications.
• Cost Efficiency: By removing only the damaged layers, milling machines can save resources and reduce the costs associated with full-depth road repairs.
• Improved Traction: The process enhances the roughness of the road surface, thereby improving vehicle traction post-repair.
• Recycling: The milled material, often referred to as Reclaimed Asphalt Pavement (RAP), can be reused, promoting sustainable construction practices.

Technical Specifications and Parameters

Milling machines come in varying sizes and capacities, suited for different project requirements. Key technical parameters include:

• Milling Width: Ranges from 300 mm to 2,200 mm, allowing for flexibility in project scale.
• Milling Depth: Typically varies between 0 to 330 mm, enabling precision in layer removal.
• Engine Power: Generally ranges from 75 to 600 kW, affecting the machine's operational efficiency and capability.
• Production Rate: Varies based on machine size, engine power, and material hardness, often ranging from 100 to 1,200 square meters per hour.
