Road cold recycling machine

Types of road cold recycling machine

The road cold recycling machine can be classified according to its characteristics and uses.

• Small-sized cold recycling machine

  Small-sized machines are usually towed by construction vehicles such as dump trucks or pull tractors. They are suitable for low-traffic-volume areas and small-scale pavement rehabilitation projects. Their flexibility, maneuverability, and low cost make them ideal choices for operators in limited spaces or for localized repairs.

• Medium-sized cold recycling machine

  Medium-sized cold recyclers are self-propelled and can be used for primary milling or cold recycling. They are suitable for relatively large-scale pavement rehabilitation projects in urban areas and rural roads. The machines can be maneuvered more easily, providing greater efficiency for cold recycling operations. Their adaptability makes them suitable for urban road rehabilitation or rural road construction.

• Large cold milling machine with recycling function

  Large cold recycling machines have powerful engines and cold milling widths of over 2.5 meters. They can handle hard asphalt pavement layers. Equipped with advanced control systems and automatic feeding and recycling functions, they achieve high-precision cold milling and material recycling. These large machines are ideal for massive road projects, intersection reconstruction, and other large-area cold recycling and regeneration operations.

Specification and Maintenance of Road Cold Recycling Machine

Knowing the specifications of a cold recycling machine helps manufacturers and those who manage road repair projects understand the limits, capabilities, and important features of that machine.

Proper maintenance ensures optimal performance and extends the lifespan of the cold recycling machine for roads. Here are some machine specifications along with their maintenance requirements:

• Working Width

  The width of the area that the road cold recycling machine can work on is typically around 1,300mm to 2,500mm. It can be maintained by regularly calibrating the machine. This ensures that the work area width matches the project needs. Regular machine width checks help avoid overlap or missed areas during road repair.

• Adjustment of Working Depth

  The road cold recycling machine can work at depths between 20 and 100mm. A machine's working depth can be changed to suit different road repair needs. Depth adjustment requires monitoring. The operator should pay close attention to the replacement depth to ensure quality repairs and avoid damage to the road or the machine.

• Repoed

  The road cold recycling machine can mill or crush material at speeds between 2 and 25 meters per minute. The machine's feeding speed depends on factors like road material and machine model. To achieve the right feeding speed, the operator should adjust the machine according to the road repair requirements. Regular machine inspections can help prevent overcrowding.

• Drum Diameter

  The diameter of the recycling drum varies between 600mm and 1,400mm. This feature greatly influences the machine's ability to handle project sizes and types. Operators should pay attention to the diameter of the drum they choose. They should consider project needs and road materials. The recycling drum should be cleaned regularly to maintain its productivity and effectiveness.

Uses of Road Cold Recycling Machines

Due to its environmental and economic benefits, the road cold recycling machine has found wide application in various road engineering projects worldwide.

• Maintenance of Old Roads and Reconstruction: The primary application of a cold in-situ recycling machine is to repair old, deteriorating roads. By recycling the existing road material, it can create a stable base or surface layer for a new road, significantly improving the use of resources and reducing landfill waste.
• Rural and Urban Road Construction: Cold recycling machines are invaluable in constructing both rural and urban roads. They enable the on-the-spot creation of quality road materials, cutting down transportation costs and time.
• Lowering Environmental Impact: By minimizing the need for new materials and reducing waste, cold recycling machines contribute to more sustainable road construction and repair, helping to lower the overall environmental impact of such projects.
• Fewer Carbon Emissions: The transportation of new materials is significantly reduced through on-site recycling, which also lowers carbon emissions and makes road construction more ecologically beneficial.
• Cost-Efficient Material Preparation: These machines enable the local production of road materials, which cuts back on importing costs and boosts economic efficiency.
• Adaptability to Material Variations: Different cold recycling machines are adjustable to various material compositions and qualities, ensuring their widespread use across diverse road engineering scenarios.

How to choose road cold recycling machines

Business buyers looking for cold in-place recycling machines for roads should focus on the following key factors.

• Project requirements analysis

  Buyers should analyze their specific project requirements before searching through available road cold recycling machine types. They should evaluate the scale and complexity of the road recycling projects. Also, they should consider the types of materials they will encounter, as well as the desired capacity and flexibility of the machine. This initial requirement assessment will help buyers make a more valid decision when selecting an IPFCR machine that suits their unique projects.

• Machine types comparison

  There are five main types of cold road recycling machines, including self-contained units, train-like units, full-cutter box units, full-width reclaimers, and simplified units. Buyers should research the working principle and features of each machine type. They should consider the advantages and disadvantages of each machine in depth, width, and material handling capacity. Buyers can choose an ideal type that aligns with their project demands from the machine types.

• Quality and durability inspection

  Buyers should choose a cold reclaimer with a sturdy build quality and reliable performance. They do so by selecting machines with robust construction that can withstand harsh working environments. Buyers should also ensure the roadside recycling machine they select is easy to maintain. Additionally, buyers should choose a machine with scalable and upgradeable functions that can adapt to changing project requirements as the business grows.

• Budget consideration

  First, buyers need to determine their budget range. Then, they will have a list of road cold recycling machines with varying prices. Buyers should select machines that offer the best value for their budget. They should consider the long-term cost of the machine, including maintenance and operating expenses over its lifespan.

Road cold recycling machine FAQ

Q1: What are the types of road cold recycling machines?

A1: There are two main types of road cold recycling machines: surface-level cold milling machines and full-depth cold milling machines. The surface-level cold milling machine focuses on only recycling a thin layer of asphalt at the surface of the road. On the other hand, the full-depth cold milling machine can take out large, varying depths of material, even up to full cuts.

Q2: What are the benefits of road cold recycling machines?

A2: Road cold recycling machines offer a number of benefits. Firstly, they can produce high-quality recycled asphalt that can be used for new road construction. Secondly, they can significantly reduce the amount of milling material that has to be sent to landfills. Thirdly, they can lower the carbon footprint of road construction projects by reducing the need for new asphalt material.

Q3: What are road cold recycling machines used for?

A3: Road cold recycling machines are used to repair and recycle roads. They remove damaged asphalt material from the road while adding new material to fix the road, all at the same time. The material that is removed can be recycled on the spot or at a central facility to create new asphalt.

Q4: How do road cold recycling machines work?

A4: Road cold recycling machines work by removing damaged asphalt material from the road. They use a high-powered rotary drum with sharp bits to mill the road and break up the damaged material. After the milling process is complete, the machine will mix in new material to fix the road.
