Q.3 A thick circular plate is used in a machine called a gyratory compactor to determine the mechanical properties of hot asphalt concrete. The plate is instrumented with load cells at points A, B, and C where each load cell is located at the same 80 mm radial distance from point O. If the load cells measure forces Fad=500 N, FBp=600 N, and Fcd ...
the mold w hen moving a gyratory mold by hand . Do not wear loose -fitting clothing items ( i.e., jewelry, ties, etc.) which may be caught in the moving parts of the gyratory compactor. Do not place hands or any other body part i nside the compaction chamber unless the E MERGENCY STOP button has been activated.
This Gyratory Compactor is used to simulate and reproduce the real compaction conditions under actual road paving operations, hence determining the compaction properties of the asphalt. It is based on the motion of the bituminous sample which generates a conical surface of revolution, characterized by the gyratory angle.
This project used the Superpave Gyratory Compactor (SGC) to analyze if SGC compaction enables improved precision of compressive strength tests for flexible base and subgrade materials and analyzed a procedure for determining the moisture-density curve of base and subgrade materials using the SGC. Also, the applicability of SGC for
Superpave Gyratory Compactor. Background . Hot-mix cold-laid (HMCL) asphalt mixes are often used as a blade-on/level-up material in Texas. Currently, the HMCL asphalt mixes are designed with a Texas gyratory compactor (TGC) and checked with the Hveem stability test. The Texas Department of Transportation (TxDOT) is undertaking an initiative
