technique des marteaux percutants

CONT: The reflex percussive technique is predominantly applied for grooving of existing runway surfaces and represents a cost-effective alternative to saw-cut grooving techniques. It has been successfully applied on various types of runway surfaces to provide adequate grooving. The technique can also effectively be used for other purposes, such as removal of rubber deposits in touchdown zone areas or for the restoration of micro/macrotexture of a degraded existing runway surface. The reflex percussive technique uses star-shaped or pentagonal disk flails.
