Asphalt Milling Machines: Powering Road Construction with KOIHO BETTER CARBIDE

What Are Asphalt Milling Machines?

Asphalt milling machines, also called cold planers, are specialized equipment designed to remove layers of asphalt or concrete from roads, bridges, or parking lots. They use a rotating drum fitted with pavement milling teeth to grind pavement into small, recyclable aggregates. These asphalt millings can be reused for new pavement, reducing costs by up to 40% compared to virgin materials and minimizing waste.

The milling process is precise, allowing operators to control depth and texture, ensuring a smooth base for repaving. KOIHO BETTER CARBIDE’s asphalt milling picks, crafted with micrograin tungsten carbide, deliver clean, uniform cuts, optimizing the output of machines like Caterpillar’s PM622 or Dynapac’s PL2000S for durable, high-quality surfaces.

How Do Asphalt Milling Machines Work?

Asphalt milling machines operate through a sophisticated system of components:

• Milling Drum: The core element, studded with road planing bits, grinds pavement to the desired depth.
• Conveyor System: Collects and transfers millings to trucks for recycling or disposal.
• Control System: Allows precise adjustments for milling depth, speed, and alignment.
• Cooling System: Uses water to manage dust and prevent drum overheating during operation.

The drum’s cutting tools are critical to performance. Poor-quality bits wear quickly, leading to uneven millings and delays. KOIHO’s asphalt grinding bits, featuring tungsten carbide tips with a Mohs hardness of 8.5-9, resist abrasion and ensure consistent aggregates, enhancing efficiency on planers like Roadtec’s RX-700 or Bomag’s BM 2200/60.

Applications of Asphalt Milling Machines

Asphalt milling machines are versatile, supporting a range of infrastructure projects:

• Highway Maintenance: Remove damaged pavement to prepare for resurfacing, ensuring smooth, safe roads.
• Urban Road Repairs: Address potholes and cracks in city streets, minimizing traffic disruptions.
• Airport Runways: Mill precise layers to maintain runway integrity and safety.
• Parking Lots: Create cost-effective, durable surfaces using recycled millings.

KOIHO BETTER CARBIDE’s pavement milling teeth excel in these applications, producing finely graded RAP that compacts seamlessly. Compatible with machines like XCMG’s XM200K or Sany’s SCM 2000C-8S, KOIHO’s tools support projects from small repairs to large-scale reconstructions.

Advantages of Asphalt Milling Machines

Milling machines offer significant benefits for road construction:

• Cost Efficiency: Recycling asphalt millings reduces material costs and disposal fees.
• Sustainability: Reusing RAP minimizes quarry use and landfill waste, supporting green initiatives.
• Precision: Adjustable settings ensure accurate milling for optimal pavement preparation.
• Versatility: Handle diverse surfaces, from soft asphalt to reinforced concrete.

KOIHO’s road milling bits amplify these advantages. Their tungsten carbide construction, with a 2,870°C melting point, ensures durability, reducing replacements and downtime. This boosts productivity and lowers fuel consumption, aligning with sustainable practices on planers like Volvo’s PL1600 or Shantui’s SM200M-3.

Challenges and Solutions in Asphalt Milling

Milling presents challenges that require robust tools and strategies:

• Tool Wear: Abrasive aggregates or metal inclusions erode standard bits, increasing costs.
• Inconsistent Millings: Uneven cuts produce coarse aggregates, weakening pavement.
• Environmental Factors: Wet or cold conditions strain tools, risking inefficiencies.

KOIHO BETTER CARBIDE addresses these with pavement planing bits featuring reinforced steel bodies and wear-resistant clamping sleeves. These tools maintain sharpness and stability, producing uniform millings even in tough conditions, ensuring seamless performance on machines like Wirtgen’s W 200 Fi.
