process in testing of aggregates
Fine Aggregate Specific Gravity Pavement Interactive
Superpave mix design is a volumetric process; it relies on mixing constituent materials on the basis of their volume. However, aggregate and asphalt binder volumes are diffucult to measure directly, therefore a material's weight is typically measured and then converted to a volume based on its specific gravity.
Manufacturing & Process Quality Control Testing RJ Lee
Quality Control Testing. The goal of the quality control testing process in industrial applications is to analyze and monitor the quality of manufacturing activities to detect problems and prevent their recurrence. Automated systems that inspect these processes play an important role in quality assessment, but they are no substitute

Introduction to Nondestructive Testing
Nondestructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the inspection or test is completed the part can still be used.
