QUESTION 11 Compaction is. O Densification by the squeezing out of water from pores under load. O A decrease in the settlement potential of soil. O Densification by rearranging soil particles without the outfilow of water. O Densification by the squeezing out of water while maintaining the same volume. QUESTION 8 For a fill that is being compacted, increasing the water content: O May help to improve compaction of the fill. O May make compaction of the fill more difficult. O May have little or no effect on compaction of the soil. All of these answers.
