Product Introduction
Ballast mats are elastic sheet-like components laid between the ballast layer and the roadbed of the railway ballasted track. Through their own physical properties, they buffer the impact of wheel-rail loads and optimize the stress state of the track, thereby protecting the roadbed and roadbed structure and improving the stability and durability of the track system.
The core material of ballast mats is polymer elastic material, and common types include:
- Rubber: Made from waste tire rubber, it has good elasticity and wear resistance, low cost and environmental protection.
- Polyurethane: Made through chemical synthesis, it has moderate elasticity, strong aging resistance, and can adapt to complex climate environments (such as high and low temperatures, ultraviolet radiation).
- Composite materials: Some products are made of rubber and polyurethane, or reinforced fibers are added, taking into account elasticity, strength and weather resistance to meet the needs of different track scenarios.
Key performance of ballast mat
Elastic buffering performance: absorb the impact energy generated by train load through its own deformation, reduce the extrusion friction between ballast particles, reduce the powdering rate, and extend the roadbed cleaning cycle.
Stress dispersion ability: transfer concentrated load to the roadbed evenly, reduce the surface compressive stress of the roadbed, avoid local settlement, especially suitable for weak roadbeds such as soft soil.
Vibration reduction and noise reduction performance: use the damping characteristics of the material to absorb vibration energy, reduce the transmission of track vibration to the surrounding environment, and reduce noise pollution (significant effect on residential areas and sensitive areas).
Weather resistance and durability: It has the characteristics of anti-ultraviolet, high and low temperature resistance, chemical corrosion resistance, etc., can adapt to different climate zones such as hot and humid, high and cold, and is not easy to age and break after long-term use.
Auxiliary drainage performance: some products adopt hollow or permeable structures, cooperate with the track drainage system to accelerate the discharge of water accumulated in the roadbed, and prevent the ballast from softening or frost heaving due to immersion.
Product Application
Ballast mats are mainly used in railway ballasted track systems. They are laid between the ballast layer and the roadbed and are widely used in passenger dedicated lines, heavy-load railways and sections with weak roadbed foundations.
They can elastically buffer train loads, reduce ballast wear and powdering, and extend the roadbed cleaning cycle; disperse loads to avoid roadbed settlement; reduce vibration and noise; relieve impact in stress concentration areas such as turnouts, and assist in drainage, thereby improving track stability and durability.
