3 cards from this section. Quick, good the night before a test.
What is Maximum Dry Density (MDD)?
It's the maximum achievable density needed for compacted soil.
Name one effect of increased water content on dry density.
Think about MDD and OMC.
What is the effect of increasing water content up to OMC on dry density?
Remember the relationship between moisture and density.
True or False: Compactive effort has a linear relationship with MDD.
Think about varying soil types and compaction methods.
A construction site requires a soil density of 1.9 g/cm³. Given that the MDD of the soil is 2.0 g/cm³ at 15% moisture, how would you adjust the moisture to achieve the desired density?
Think about the relationship between moisture levels and density.
You are tasked with choosing a compaction method for a project involving both coarse and fine-grained soils. How would you approach selecting the appropriate techniques?
Consider the attributes of each soil type and how they interact with compaction methods.
