LIGHT WEIGHT ROAD FOUNDATIONS
The pictures shows shots of a road being in filled with Foam Concrete on a peat bog with the type 1 stone being laid on top together with the black top.
The mix used was a 250kg/m³ and 500kg/m³ density with a 28 day strength of 0.2 and 1N/mm² @ 28 days. The depth of the Foam Concrete was 1 metre with 50cm of type1 fill then 10cm of black top.
The combination of lightweight ease of placement and self levelling properties requiring no vibration or compaction renders Foam Concrete an excellent foundation for roads.
