Abstract:
An apparatus for managing degree of compaction in a vibratory compacting vehicle having a roll to be vibrated comprising:a vehicle speed sensing means which senses a traveling speed of the vehicle; a vibration number setting means by which a number of vibrations of the roll transmitted per unit time is set; a reference vibration number setting means by which a reference number of vibrations of the roll transmitted per unit of longitudinal travel of the vehicle is set; a control means controlling electric signals outputted from the vehicle speed sensing means, the vibration number setting means, and the reference vibration number setting means, respectively; and an indicating means 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 transmitted per unit of longitudinal travel of the vehicle on the basis of an electric signal outputted from the control means.
