Capa anticongelante

Para afrontar de la forma más eficiente posible la construcción de la autopista A1 en Polonia, en el extendido y compactación se utilizaron casi exclusivamente máquinas del Wirtgen Group, entre ellas, varios compactadores y rodillos tándem de HAMM.

Because heavy goods traffic is set to grow to enormous proportions, the A1 highway needed a road surface designed to withstand heavy loads. A 20 cm thick gravel layer serves as frost protection.

The A1 highway in Poland received a particularly robust road bed. The first step was creating a stabilized sub-base 50 cm thick that that was compacted with padfoot drums.

Hamm oscillation technology enabled a frost protection layer to be gently compacted without damaging the adjacent buildings.
