Abstract
An apparatus for managing degree of compaction includes: a sensor 13 which senses a traveling speed of the vehicle; a switch 14 by which a number of vibrations of the roll transmitted per unit time is set; a reference vibration number setting section 15 by which a reference number of vibrations of the roll transmitted per unit of longitudinal travel of the vehicle is set; an input/output calculating section 16 controlling electric signals outputted from the sensor 13, the switch 14, and the reference vibration number setting section 15, respectively; and a monitor section 17 relatively and comparatively indicating, as a vehicle speed index value, magnitude relation of a current number of vibrations of the roll transmitted per unit of longitudinal travel of the vehicle relative to the reference number of vibrations of the roll on the basis of an electric signal outputted from the input/output calculating section 16.
