Internal Angle Measurement Apparatus
Description & Specification
Internal Angle Measurement Apparatus
Categories:
Asphalt Mix Testing
Technical Specifications
The importance of a precise gyratory angle has been widely noted. The measurement of the internal angle represents, in practice, the most accurate method of calibration. This method comprises two individual values: angle between cylinder and top plate and angle between cylinder and bottom plate.
The average of these two values is taken as the "internal angle". To date the internal angle calibration of gyratory compactors has been considered a difficult task leading to wide variations in results even between machines of the same brand.
Main Features:
Accurate calibration of internal angle of Gyratory compactors and verification of frame stability, to international Standards
Quick and accurate measurement of the internal gyratory angle: less than 30 minutes
Ideal for periodic verification of the internal gyratory angle
Compatible with any make of Gyratory compactors
No hot mix required: when, placed into the mould, the device reproduces the internal shearing forces generated by the hot mix during compaction
Battery operated.
Technical Specifications:
Reproducibility is in 0.01° Class, fitting to all Standards
Overall dimensions: 150 mm dia., 115 mm high
Weight approx.: 5.6 kg.
