RATIOS
A ratio is a comparison of two things. It's the relationship of one value compared to another.
​
Examples:
​
Density Ratio = Field Density vs Lab Compacted Density
​
Field Wet Density (nuke reading) = 2.125 t/m³
Peak Converted Wet Density (lab compaction) = 2.111 t/m³
​
Moisture Ratio = Field Moisture Content vs Optimum Moisture Content
​
Field Moisture Content (FMC) = 15.8%
Optimum Moisture Content (OMC) = 18.2%
​
​
​
​
This material is drier than OMC.
​
​
California Bearing Ratio = How your material compares to the standard material (crushed limestone from California)
​
CBR of 50 means your material is half as good at bearing a load as the California limestone
CBR 110% means your material is better at bearing a load than the California limestone
