Fully Electro-Mechanical Gyratory Compactor GALILEO
- Controls - Galileo 78-PV20G0X
- High precision
- User-friendly PC software
- Easy specimen extraction
A robust precision-engineered steel structure incorporating the EMS Electromechanical servo-actuation mechanism for vertical load application and "Orbital" proprietary gyration and mold rotation system.
(Patent pending) delivering highly accurate and repeatable test results, together with stiffness and angle stability values that fall comfortably within the limits defined in EN 12697-31.
The large 7 "user-friendly integrated touch screen control panel shows the real-time test graph
The on-board firmware includes nine languages and also offers the option to control the tests from a PC
A traceable calibration certificate conforming to ASTM and AASHTO Standards is also included.
Operating principle
Standard specifies the method for compaction of cylindrical specimens of bituminous mixtures using a gyratory compactor. Such compaction is achieved by combining a rotary shearing action with a vertical static force applied by a mechanical head.
The method can be used for:
- Preparation of specimens of a given height at a predetermined density, for subsequent testing of their mechanical properties;
- Derivation of a curve of density versus the number of gyrations;
- Void content for a given number of gyrations.
Standards apply to bituminous mixtures (made either in the laboratory or from on-site sampling),with aggregates not larger than 37.5 mm. During operation, the bituminous mixture is contained in a cylindrical mould (100 or 150 mm diameter). Compaction is achieved by the simultaneous application of a low-static compression and a shearing action, which results in the motion of the center-line of the test piece, which generates a conical surface of revolution while the ends of the test piece remain approximately perpendicular to the axis of the conical surface.
The gyratory compactor Galileo can be used as part of your Superpave performance-based testing program.
