Road Construction

Road Construction on Challenging Ground Conditions

Many roads are built in areas with challenging ground conditions, such as soft clay and peat soils. In these situations, lightweight materials can be used to reduce the risk of settlements and, in the worst case, ground instability.

Soft and sensitive soils can be vulnerable to additional loads. If overloaded, they may experience settlements and reduced stability, leading to costly repairs and maintenance.

Benefits of Foamit Foam Glass in Road Construction

Foam glass aggregates are one of the lightest granular construction materials available. Its low density makes it particularly well suited for road construction projects.

In addition to reducing the risk of settlements, the lightweight properties contribute to improved project efficiency. The volume of soil that needs to be excavated and removed to compensate for the weight of the embankment can be significantly reduced compared to traditional fill materials. This can lower both project costs and environmental impact.

Frost Protection for Roads

Foam glass aggregates contain approximately 80% enclosed air, providing excellent thermal insulation properties.

Its insulating capacity helps maintain temperatures above freezing in frost-susceptible layers of the road structure, reducing the risk of frost heave and frost-related damage.

The material’s low weight also makes it easy to handle and install.

Once placed, foam glass aggregates form a stable layer that can be worked on directly. Installation and compaction can be carried out efficiently using conventional construction equipment.

The combination of stability, low weight, drainage capacity, and thermal insulation helps reduce the risk of settlements, water-related damage, and frost heave. This can contribute to lower maintenance requirements throughout the service life of the road.
