A two-component polyurethane ballast adhesive (PU-50D, A:B = 3:2) sprayed into the track bed — locks ballast against displacement, cures to a tough permeable elastomer, cuts rail wear and noise while keeping the bed draining.
High-Speed Rail Ballast Bonding
A two-component polyurethane ballast adhesive (PU-50D, A:B = 3:2) sprayed into the track bed. It locks the ballast against displacement, cures to a tough, permeable hard elastomer that still lets the bed drain, cuts rail wear and damps noise. See the full railway ballast adhesive guide.
