MACT RapidRoad (Silica-Free Rapid Road Repair Binder)
Target Audience: Mine Site Supervisors, Civil Maintenance Crews, Quarry Managers, Infrastructure Managers needing extremely fast, durable repairs for high-traffic areas.
Ultra-Rapid Hardening, Silica-Free Binder for Heavy-Duty Road Repairs - Trafficable in < 30 Minutes
Overview
MACT RapidRoad is a revolutionary, silica-free binder engineered for the ultra-rapid repair of concrete and asphalt pavements in demanding industrial environments. When mixed with standard aggregate, RapidRoad creates a high-strength concrete that achieves trafficable strength (< 30 minutes) significantly faster than traditional repair materials, drastically minimizing downtime for critical haul roads, hardstands, and access ways. Its unique chemistry allows for application even in damp or wet conditions, and its silica-free nature (<0.1% RCS) enhances worker safety during mixing and placement.
Key Technical Advantages
- Extreme Speed: Sets in < 15 minutes and achieves sufficient compressive strength for heavy vehicle traffic in under 30 minutes.
- High Strength & Durability: Develops >20 MPa in 24 hours, forming a robust, wear-resistant patch capable of withstanding heavy, repetitive loading.
- Silica-Free Safety: Contains <0.1% crystalline silica, protecting workers from hazardous dust exposure.
- All-Weather Application: Can be successfully applied in damp conditions and even cures underwater, ensuring repairs can proceed regardless of weather.
- Simple Use: Requires only mixing with locally sourced aggregate (e.g., 10-20mm ballast) and water – no specialized equipment needed.
- Versatile Repairs: Ideal for potholes, large depressions, spalls, and creating temporary ramps or transitions.
- Operational Efficiency: Minimizes disruption to traffic flow and operational schedules.
