Морозозащитный слой в дорожном строительстве

Для максимально эффективного строительства автомагистрали A1 в Польше при укладке и уплотнении использовались почти исключительно машины Wirtgen Group, в том числе несколько грунтовых катков и тандемных дорожных катков 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.
