Pavement Design

Rigid and Flexible Pavement Subgrades

Soil Characteristics Pertinent to Roads and Airfields Holtz, Robert, et.al. An Introduction to Geotechnical Engineering. Second Edition, 2011.

Practice Problem Given: a soil, classified as CL according to the USCS, is proposed for a compacted fill Required: consider the soil to be used for: a)Subgrade b)Earth dam c)Foundation support for a structure Comment on, using Table 5.5: 1.The overall suitability of the soil 2.Potential problems of frost 3.Significant engineering problems 4.Appropriate compaction equipment to use
