Control Uniformity Of Bituminous
◊ Control of the uniformity of hot mixes is important, as any appreciable change or variation in gradation or bitumen content will be reflected in a change in some other characteristic of the mix.
◊ Sampling and testing are among the most important functions in plant control.
◊ Samples may be obtained at various points in the plant to establish if the processing is in order up to those points.
◊ A final check of the mixture is needed to determine its uniformity, its gradation, and its bitumen content.
◊ An extraction test measures the bitumen content and provides aggregate from which the gradation may be determined.
◊ The results of extraction and gradations should fall within the job mix tolerance specified, if they do not, corrective measures must be taken to bring the mix within the uniformity tolerance.
