ABSTRACT:
An apparatus 400 and a method are provided for increasing the density of a compactible material 10 while continuously evaluating the density of the material. The evaluation of material density is carried out by calculating the total of the static, dynamic and centrifugal forces applied by a vibrating tool 102 l to the compactible material 10. The total applied force calculation includes measuring the vertical acceleration of the material contacting member 102 and the position of an eccentric mass 206 mounted on the material contacting member 102. The acquisition of these parameters is carried out simultaneously, and the calculation of the dynamic and centrifugal forces is made when the material contacting member 102 is at its lowest position.
