Asphalt Testing Accessories

Accessory sets for testing asphalt samples with UNIFRAME machines.

Standards EN 12697-33 ASTM D8079

Uniframe accessories Multiproduct
Description

The slab compactors can compact asphalt slabs to a target density applying specific loads corresponding to those of pavements rollers used in the highway construction. The slab can be used for: 

  • Wheel tracking test down to 38 mm thickness
  • Cored to provide specimens for indirect tensile, static and dynamic creep tests
  • Cut into beams for benfing fatigue tests

The slab compactors are proposed in two versions:

  • Standard models
  • Advanced models, which also satisfy the compaction procedure of the brand new EN 12697-33 method 7.3 and include other important features. 

Electromechanical slab compactors feature a compacting system by roller segment head radius 535 mm. The roller segment freely moves by simple friction for better compaction uniformity. A brushless motor (standard models), or stepper motor (advanced models) moves vertically the roller segment under displacement control. the vertical load is applied orthogonally to the axis of the travel motion. the mould carriage moves back and forth by linear movement. The longitudinal (major) mould dimension correspond to the compaction direction so it is possible to obtain specimens of the proper lenght conforming to Standards. The lifting machine cover permit an easy access to the mould area. In the “rest” position, the mould is close to the operator for easy positioning while the roller segment is lifted and positioned at the back of the machine.

The Electromechanical slab compactor can be used as part of your Superpave performance based testing program.

Main Features
    • Completely electromechanically operated
    • Possibility to program user defined procedures as free combination of load and displacement (or combined) controlled cycles
    • Completely electromechanically operated
    • Conforming to EN 12697-33, 5.2 method and ASTM D8079
    • 21” All-in-one touchscreen PC controlled , PC and software included
    • Includes the compaction procedure defined in the brand new EN 12697-33 method 7.3, providing at the beginning a controlled displacement compaction which can grant a flat surface followed by a load compaction phase , which can replicate the real compaction on the road surface
    • Base and foot adjustable heating system available as option
    • Mould dimensions: 500 x 400, 500 x 300, 400 x 300, 300 x 300 and 320 x 260 mm, 195 mm height
    • Compaction direction in the longest (major) mould dimension to obtain specimens of the proper length conforming to Standard
    • Vertical balanced of sliding cover for easy access and complete three side view
    • Maximum compaction load 30 kN
    • User defined controlled linear speed up to 300 mm/sec and adjustable pause at the mould inversion point
    • Ideal for producing test beams for 4-Point bending (EN 12697-24, EN 12697-26, AASHTO T321) and slabs down to 38 mm
    • Vibrating roller option, adjustable from 10 to 50 Hz
    • PRO-COMPACT* closed loop control slabs
    • Customization of compacting cycle which can be saved and recalled from the database
     

    *PRO-COMPACT closed-loop is an innovative mechanical and electronic control that combines orthogonality of the load, pendulum motion of the head and sinusoidal non-friction forward-reverse carriage movement. This results in an optimally compacted sample that features Planarity Regularity and hOmogeneity (PRO). The combined load/displacement compaction procedure provides at the beginning of the test a controlled displacement compaction, which can grant a flat surface of the compacted slab, followed by a load compaction phase, which can replicate the real compaction on the road surface.

Standard Asphalt Slab Roller Compactor

The slab compactors can compact asphalt slabs to a target density applying specific loads.

70-T1282 Uniframe load machine
Description

The slab compactors can compact asphalt slabs to a target density applying specific loads corresponding to those of pavements rollers used in the highway construction. The slab can be used for: 

  • Wheel tracking test down to 38 mm thickness
  • Cored to provide specimens for indirect tensile, static and dynamic creep tests
  • Cut into beams for bending fatigue tests

The slab compactors are proposed in two versions:

  • Standard models
  • Advanced models, which also satisfy the compaction procedure of EN 12697-33 and include other important features. 

Electromechanical slab compactors feature a compacting system by roller segment head radius 535 mm. The roller segment freely moves by simple friction for better compaction uniformity. A brushless motor (standard models), or stepper motor (advanced models) moves vertically the roller segment under displacement control. the vertical load is applied orthogonally to the axis of the travel motion. the mould carriage moves back and forth by linear movement. The longitudinal (major) mould dimension correspond to the compaction direction so it is possible to obtain specimens of the proper lenght conforming to Standards. The lifting machine cover permit an easy access to the mould area. In the “rest” position, the mould is close to the operator for easy positioning while the roller segment is lifted and positioned at the back of the machine.

The Electromechanical slab compactor can be used as part of your Superpave performance based testing program.

Main features
  • Completely electromechanically operated
  • Conforming to ASTM D8079
  • 8” touchscreen controlled
  • Automatically compacts in displacement controlled mode up to target density/height or up to the (user selectable) load limit
  • Mould dimensions: 500 x 400, 500 x 300, 400 x 300, 300 x 300 and 320 x 260 mm, 195 mm height
  • Compaction direction in the longest (major) mould dimension to obtain specimens of the proper length conforming to Standard
  • Vertical balanced of sliding cover for easy access and complete three side view
  • Maximum compaction load 30 kN
  • User defined controlled linear speed up to 300 mm/sec and adjustable pause at the mould inversion point
  • Ideal for producing test beams for 4-Point bending (EN 12697-24, EN 12697-26, AASHTO T321) and slabs down to 38 mm
  • Adjustable heating control system of the sector heads available as option
  • Vibrating roller option, adjustable from 10 to 50 Hz
  • *PRO-COMPACT closed-loop control slab

 

*PRO-COMPACT closed-loop is an innovative mechanical and electronic control that combines orthogonality of the load, pendulum motion of the head and sinusoidal non-friction forward-reverse carriage movement. This results in an optimally compacted sample that features Planarity Regularity and hOmogeneity (PRO).
The software is able to combine a load/displacement compaction. This procedure provides at the beginning of the test a controlled displacement compaction, which can grant a flat surface of the compacted slab, followed by a load compaction phase, which can replicate the real compaction on the road surface.

UNIFRAME-MINI Automatic Testing Machine for Transverse Deformation of Tile Adhesives and Grouts

Designed for transverse deformation testing of tile adhesives and grouts

Standards EN 12004-2

UNIFRAME-MINI, Automatic testing machine (70-T0108/MINI)
Description

 

The UNIFRAME-MINI machine is a fully automatic unit specifically designed for transverse deformation testing of tile adhesives and grouts in conformance with the stringent requirements of EN 12004.
Great attention has been given to the machine design, as shown by the high-stiffness frame which allows wide access to the test area, the robust loading anvil and supports, the easily readable touchscreen graphic display mounted at head-height and oriented towards the user at a comfortable angle, the appropriately positioned connection ports on the rear of the machine and the compact and ergonomic overall construction.
During operation, the machine measures the transverse deformation of a tile adhesive or grout strip specimen with prescribed dimensions (3mm thickness), whilst subjecting it to a 3-point bending load which is gradually increased in such a way that the transverse deformation is constant at 2mm/min. The test is completed when failure occurs.
The transverse deformation rate is automatically controlled by an advanced closed-loop controller based on a customized algorithm. 
Main features

 

  • Compact, solid and ergonomic design
  • Class 1 accuracy (load and deformation)
  • High productivity
  • Fully automatic test cycle. The complete test cycle is automatically performed by simply pressing the start button. Correct test execution conforming to the reference Standard is continuously and automatically controlled.
