Soil Compactibility Classes
This page presents the assignment of different soil types to three compactibility classes based on German standards. As per ASTM, non-cohesive to cohesive soils as well as coarse-grained and mixed soils (sand and gravel) have good compactibility characteristics.
Table:
Compactibility class V1 to V3 as per ZTVA-StB 97 [ZTVAStB97]
Compactibility class | Description | Soil Group as per DIN 18196 |
---|---|---|
Good compactibility (V 1) |
Non-cohesive to cohesive, coarse-grained and mixed soils (sand and gravel) |
GW, GI, GE, SW, SI, SE, GU, GT, SU, ST |
Moderate compactibility (V 2) |
Cohesive, mixed-grained soils (Gravel and sand with a large clay or silt portion) |
GU, GT, SU, ST |
Not easy compactibility (V 3) |
Cohesive, fine-grained soils (Clays or silts) |
UL, UM, TL, TM |
In this context, the tabular information on the classification of soils for civil engineering purposes in this Table may be interesting.
