Frost Protection Layer in Road Construction

Preventing Frost Damage

The frost protection layer keeps water from rising into the pavement, and as a result, prevents frost damage to the surface layer. For this purpose, rock is crushed and screened into graded aggregates, which are then laid and compacted. The graded, compacted aggregates ensure that the layer is sufficiently permeable to water and disrupts the soil’s capillarity.

"The mobile impact crusher MOBIREX MR 130 Z EV02 guarantees the optimum material preparation required before the frost protection layer compaction."

When it comes to compaction, surface performance, precise steering, and compaction force are critical to quality and cost-effectiveness – all properties of Hamm’s heavy compactors.

“Two HCQ modules are available to monitor the load bearing capacity during soil compaction: the HAMM Compaction Meter HCM and the HCQ Navigator.”

Job Reports about Paving a Frost Protection Layer

To build the A1 motorway in Poland as efficiently as possible, machines from the Wirtgen Group were almost the only equipment used during paving and compaction, including several HAMM compactors and tandem rollers.

Europe's largest construction project

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.

Europe’s largest construction project

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.

A Sturdy Road Structure

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