2.5 Road Base – CBR 15

2.5 Roadbase – CBR 15 is a compactable material that consists of crushed rock and fine aggregates. It is engineered to achieve a California Bearing Ratio of 15, indicating a moderate strength suitable for use in sub-base layers for roads, paths, and driveway constructions, especially in areas with light traffic. The 2.5 refers to the nominal size of the aggregates used, making it ideal for providing a stable and well-drained foundation. This road base ensures optimal distribution of load and helps in preventing settlement and erosion. It is often used in landscaping and small civil works where a moderate load-bearing capacity is required.

Typical Use Cases

Sub-base layer for residential and light traffic roadways
Foundation for footpaths and bike paths
Driveway construction for domestic applications
Base for paving and small parking areas
Fill material for landscaping and civil engineering projects
