Figure 5.13 Measured water content by K-F as function of actual water content
Figure 5.13 shows measured water content by K-F method as function of
actual water content. At different water amounts in diluted bitumen, measured
water content values are close to the actual water content. The largest deviation
between the measured water content and actual water content is less than 5 %.
