Ballastless track slabs & structures reinforced with Ecocrete™ PP Monofilament Fiber
Tropical heat & wind: PP monofilaments create a 3D network that limits plastic shrinkage during hot-weather placement, helping minimize map cracking.
Ballastless track tolerances: Added post-crack toughness supports edge integrity at anchors, dowels, and rail seats, reducing spalls and patching.
Precast production: Fibers mix quickly, are pump-friendly, and do not rust, protecting segments during storage, transport, and erection.
Maintenance durability: Improved impact and abrasion resistance helps track slabs withstand repeated access, grinding, and cleaning operations.
Construction teams reported tight crack control in hot pours, crisp saw-cut joints, and reduced edge repairs around fastener pockets. Fiber reinforcement supports lifecycle cost savings by lowering cosmetic patching and unplanned maintenance, keeping key track sections available for commissioning and service.
Crack Control for Ballastless Track and Precast Elements
The Jakarta–Bandung HSR crosses long viaducts, tunnels, and complex urban interfaces. To reduce early-age shrinkage cracking and improve surface quality in ballastless track slabs, precast girders, pier caps, and station platforms, the concrete mix adopted Ecocrete™ Polypropylene Monofilament Fiber. The uniformly dispersed micro-fibers help arrest micro-cracks at initiation, support cleaner joint arrises, and enhance abrasion and impact resistance from construction traffic and maintenance cycles.
