• No random cracks and no interfacial cracks by calculated cracking control
• Suitable for modernization and new lines
• Can be used on soil bodies, on bridges and in tunnels
• Suitable for tramways, rapid transit andstandard-gauge railroads Easy to repair in the event of damage (replacement of damaged support points, repair or replacement by high-early- strength mortar or concrete)
