Constants
- ESTIMATED_VALUES
The reference charts do not actually include these lines,
so this is what we think they would be.
How the interpolated values were determined [concrete: q5, q7, q8]:
Average (or weighted average) of the lines surrounding it. This should be a good estimate.
How the extrapolated values were determined [asphalt: q8, q9, q10; concrete: q10]:
Took the difference between the last two known, observed q-value arrays, and added that difference to the last known q-value array. (Asphalt Ex: q8 = q7 + (q7 - q6), q9 = q7 + 2(q7 - q6), etc.) This estimate may be less accurate.
