The specific laboratory testing that was performed on the representative samples obtained are
' discussed below:
• Soil classification
' Moisture content
Sieve analyses
• Hydrometer analyses
' In situ density
)\4oisture-density relationship
• Compaction (Standard Proctor)
' Time Consolidation
Results of the testing program are summarized in a series of tables and figures included in this
' appendix. Table C-2 presents a summary of index properties and compaction tests.
Table C-3 presents a summary of the time consolidation tests.
' 1. Soil Classification: Numerous soil samples were classified in the laboratory in accordance with
the Unified Soil Classification System (USCS) and the ASTM D 2487 method. Findings are
shown in Table C-].
