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

Feature:

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


Specification:


Models 77-PV41C05
77-PV41C06
Machine control - Vertical load and/or displacement control of the roller segment by stepper motor, measured directly by linear transducer to verify in real time the specimen thickness for more accuracy
- Real time measurement and control with a closed loop logic of compaction load by two precision strain gauge load cells. This system permits to verify possible discrepancies of the compaction due to the wrong distribution of asphalt in the mould  and to any other unexpected malfunctions, with warning to the operator
- Machine fitted with sensors to confirm the mould in position and for the automatic set-up of the horizontal travel
Software - 21'' Touchscreen integrated PC
- Fully programmable PC software operating in Windows®
- Set up of customized compaction sequence as free combination of load/displacement controlled cycles
- Selection, customization and storing of test parameters
- Customization of the compacting sequence to be saved and recalled from the database
- Graphic display of displacement / force vs. number of passes or load vs. displacement
Max. vertical force 30 kN
Load measurement By two precision load cell
