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
