As illustrated in Figures 4.17 and 4.18, the ACT results are consistently lower than the conventional (manual) wet cohesion results. The possibility of correcting the ACT results by a correction factor or model was then investigated. This was done by pooling the data from Temple Systems and MACTEC into a single data set and plotting “automated” versus “manual” results, as illustrated in Figure 4.19.

A correction factor of 1.75 (=1/0.5711) can be used to bring the Automated values within the range of values obtained from the conventional wet cohesion test. A plot of corrected values versus the conventional ones is shown in Figure 4.21. 56
