A Brief Understanding of Tarmac Cutting Discs

Table of Content [Hide]

    With the continuous advancement of urban infrastructure construction, projects such as roads, bridges, and parking lots have raised higher demands for the cutting precision and efficiency of pavement materials. In road construction, composite pavement materials made of asphalt (tarmac) and gravel are widely used, and the tarmac cutting disc is an important tool specially designed for cutting such materials.


    Introduction to the Tarmac Cutting Disc


    The tarmac cutting disc is a specialized blade used for cutting composite pavement materials consisting of asphalt mixtures and concrete containing gravel. It is commonly used in road construction, maintenance, and emergency repair projects. It is usually made of diamond or other high-hardness abrasives, featuring high strength, high wear resistance, and high temperature tolerance. It can effectively handle the dual wear caused by the "soft-hard" combination of asphalt and gravel on the tool during cutting.


    Structure and Performance Characteristics of the Tarmac Cutting Disc


    Blade material


    The tarmac cutting disc mostly adopts diamond blade heads, whose hardness is second only to natural diamonds, enabling easy cutting of concrete or asphalt materials containing gravel.


    Core design


    Generally made with a high-strength steel core, the diamond blade segment is firmly bonded through laser welding, silver soldering, or hot pressing and sintering, ensuring it does not easily detach during high-speed operation and guaranteeing construction safety.


    Chip removal and cooling groove design


    Some high-end cutting discs are designed with chip removal grooves and cooling holes, which help lower the temperature and speed up debris discharge during dry or wet cutting processes, improving cutting efficiency and extending service life.


    Cutting performance

    blade has excellent cutting power and sharpness, capable of quickly cutting asphalt structures of various thicknesses without damaging the base, producing neat cuts with smooth edges.


    Purchase and Usage Recommendations


    Choose the appropriate type according to construction materials


    Different asphalt composition ratios require different cutting discs. For example, concrete pavements with more gravel and higher strength require blades with higher hardness.


    Consider the cutting method


    For dry cutting, choose discs with good heat resistance; for wet cutting, use water cooling to prevent overheating and burning.


    Match with suitable cutting equipment


    The tarmac cutting disc should be used with pavement cutters, high-speed angle grinders, and other equipment, ensuring the disc diameter and connection size are compatible.


    Pay attention to safe operation


    Wear protective goggles, ear protection, and other safety gear during cutting, and follow the speed and feed rate recommendations provided by equipment and blade manufacturers to ensure construction safety.


    Conclusion


    As an indispensable tool in road engineering, the professionalism and technology of the tarmac cutting disc are continuously improving. Through scientific selection and standardized operation, construction units can significantly enhance cutting quality and efficiency while reducing maintenance costs. Whether in routine road maintenance or emergency repair work, understanding and properly using the tarmac cutting disc will safeguard project quality and progress.
