In general, statistical process control techniques help to provide experience in "process thinking" (a central tenet of HACCP), develop an historical record of performance, evaluate the long-term stability of a process and determine process capability (i.e., how it is actually working), and judge the effectiveness of process improvement actions ...
Table 1 pre- sents these results. Statistical tech- niques were then used to compare results for parameter changes to deter- mine if apparent differences were sta- tistically significant. Results As a result of this study, VOC emission factors for the drum-mix asphalt process are established to be in the range of 0.1 to 0.4 pounds carbon per ton.
"Before we had PWL, we had an inspector in the plant helping the contractor to make adjustments. It wasn't as scientific a way to do things. A contractor should control his own quality. "By using a statistical control method, we get a better measure of the actual quality of the asphalt mixtures," says Bradbury.
