Product Introduction
Railway under sleeper pads require precise structural design to match the bottom profile of sleepers, typically adopting flat or locally protruding shapes. The protruding parts enhance friction with the sleeper to prevent displacement after installation.
The installation process must align with track construction progress, usually carried out after sleeper placement but before rail installation. Workers manually position the pads to ensure full contact with the ballast bed, with specialized tools occasionally used for fixation in certain scenarios.
From a maintenance perspective, these pads reduce direct wear between sleepers and the ballast bed, decreasing the frequency of sleeper replacement caused by surface damage. They also facilitate later adjustments to rail elevation, serving as an important auxiliary component that improves the efficiency of track system maintenance.
Rubber pad performance advantages
Superior Elasticity：The natural rubber material exhibits high elastic recovery rate, effectively absorbing wheel-rail impact vibrations with remarkable damping effects that significantly reduce dynamic loads on the track structure.
Exceptional Durability：With outstanding wear resistance and anti-aging properties, it adapts well to complex outdoor climatic conditions. Long-term use rarely causes cracking or hardening issues, ensuring extended service life.
Excellent Compatibility：The high friction coefficient at contact surfaces with sleepers and ballast beds prevents post-installation displacement. Its adaptable design ensures stable fitting with various sleeper base profiles, guaranteeing installation stability.
Superb Insulation Performance：As an excellent insulating material, the rubber effectively reduces stray currents in the track system, actively protecting track circuits and related equipment.

Product Application
Surface Preparation
Thoroughly clean both the sleeper base and ballast bed surfaces to ensure contaminant-free bonding interfaces.
Precision Installation
Align the rubber pad perfectly with the sleeper profile, applying gentle pressure to achieve full contact without wrinkles or air gaps.
Environmental Considerations
Avoid installation during precipitation or high humidity conditions. In cold weather (<5°C), verify the pad remains pliable without embrittlement before installation.
