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 sieved 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 MR 130 Z EVO2 mobile impact crusher equipped with a secondary screening unit is perfect for materials processing.”

When it comes to compaction, surface performance, high-precision steering, and compaction force are critical to quality and cost-effectiveness.

“Two HCQ modules are available for monitoring bearing capacity during compaction in earthworks: the HAMM HCM compaction meter and the HCQ navigator.”
