The gyratory compactor has been used for concrete materials in Finland and Scandinavia. The method is used for mix design and quality control mainly in concrete product plants, where low workable and zero slump concrete is used (for such products as hollow-core slabs, tubes and pmore...
Gyratory compaction is considered to be one of the best methods of laboratory compaction for the assessment of compactibility and the manufacture of test specimens. Compaction is achieved by the application of a vertical stress (normally 600KPa) via end platens to a known mass ofmore...
This instrument is built to SHRP & US Federation Highway Administration specifications. It produces asphalt specimens that best predict long-term pavement performance. The SHRP Superpave™ program uses specimen height from each gyration during the consolidation cycle as the basimore...
