Gyratory Compactor

This Gyratory Compactor, entirely developed and manufactured by Matest, is used to simulate and reproduce the real compaction conditions under actual road paving operations, hence determining the compaction properties of the asphalt. Such compaction is achieved in a fully automatic way, by combining the rotary action and the vertical resultant force applied by a mechanical head. The Compactor comprises a highly rigid steel frame ensuring excellent angle control. Load is applied by an electro-pneumatic cylinder, servo-controlled by a precision pressure regulator; the height is measured by a linear transducer.

A high quality machine with which the user can easily and safely obtain accurate, repeatable results day after day. 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 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.

A high quality machine with which the user can easily and safely obtain accurate, repeatable results day after day.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 600 kPa) via end platens to a known mass of asphaltic mixture within a 100 or 150mm internal mould. The longitudinal axis of the mould is rotated (gyrated) at a fixed angle to the vertical whilst 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. The compaction progresses and it is also saved in Microsoft ExcelTM compatible format. The operator can choose whether to compact for a certain number of gyrations or until a target mixture density or void content is achieved.Problems with existing compactors are mainly related to build quality and ease of use. Unlike most compactors 100 and 150mm moulds can be tested without changing machine parts. A filled gyratory compactor mould is heavy and often very hot. In many cases these moulds have to be lifted in and out of gyratory compactors. With the Gyratory Compactor CRT GYR EN, no lifting of filled moulds is required. They are automatically lowered into position for compaction and then lifted up again for transfer to the integrated demoulding system. See what CRT-GYR asphalt compaction configurations Cooper suggests.
