Web6 Mar 2024 · sandy soils are next, with CBR values of 6 to 8. The best soils for road-building purposes are the sands and gravels whose CBR values normally exceed 10. Most Iowa soils rate fair-to-poor as subgrade materials. The change in pavement thickness needed to carry a given traffic load is not directly proportional WebOver-excavation. The general principle is to replace poor load-bearing in situ subgrade with better load-bearing fill. Typically, 0.3 – 0.6 m (1 – 2 ft.) of poor soil may be excavated and replaced with better load-bearing fill such as gravel borrow. Add a base course and perhaps a subbase course over the subgrade.
