Safe for drivers
For the paving of two junctions that connect Warsaw to the A2 highway, our teams applied a special treatment of the surface that improves road safety. In fact, spraying the surface of fresh concrete with a retarder plays a key role in making roads safer. Twelve to 24hours after site-pouring, when the concrete has reached its early strength, the top layer can be removed with steel brushes to expose the aggregate layer, which provides friction for vehicle traffic.
