Superpave GYR Gyratory
Supports the following standards: AASHTO T312, CS9010-1115, CS9010-1230, SHRP M-002, T 0736-2011, TEX-241-F, EN 12697-10
Compaction is achieved by the application of a vertical stress (normally 600KPa (87psi)) via end platens to a known mass of asphaltic mixture within a 150 and 100mm (6 and 4inch) internal Ø mold. The longitudinal axis of the mold is rotated (gyrated) at a fixed angle to the vertical while the platens are kept parallel and horizontal. During compaction the height of the sample is automatically measured and both the mixture density and void content calculated.
Features:
- Automatic mold insertion and retraction on side table which allows cooling time before extraction without loss of compaction time (especially important for rubberized asphalt)
- 150 mm and 100 mm (6 and 4 inch) internal Ø molds can be tested without changing parts
- Cold mix (emulsion) materials can be compacted and the expelled fluid collected
- Ethernet and multiple USB connections for data acquisition and control system
- User friendly LabVIEW™ software displays results in real time
- Machine calibrated with traceable equipment
- Option for mold up to 300 mm (11.8 inch) high
Software:
- User friendly, intuitive and reliable Windows® software developed using LabVIEW™
- Software allows 3 methods of compaction – number of gyrations, height and target density. The operator is guided through every step of the compaction
- Real-time display of current height, density & void content (%) Data is recorded to disk at regular intervals for further analysis
- Utilities are included for transducer check, diagnostic routines and calibration
