Abstract
A method and apparatus for controlling the inflation pressure on a pneumatic compactor. The method and apparatus includes means for dynamically determining a level of density of a material to be compacted, a control system for determining a desired inflation pressure as a function of the density, and an inflation pressure system for adjusting the inflation pressure in response to the desired inflation pressure.
Claims15
A method for controlling the inflation pressure of a set of tires on a pneumatic compactor, including the steps of:
- dynamically determining a level of density of a material to be compacted;
- determining a desired inflation pressure in proportion to the dynamically determined density;
- and
- adjusting the inflation pressure in response to the desired inflation pressure.
An apparatus for controlling the inflation pressure of a set of tires on a pneumatic compactor, comprising:
- means for dynamically determining a level of density of a material to be compacted;
- a control system located on the compactor and adapted to determine a desired inflation pressure in proportion to the dynamically determined density;
- and
- an inflation pressure system located on the compactor and adapted to adjust the inflation pressure in response to the desired inflation pressure.
A method for controlling the inflation pressure of a set of tires on a pneumatic compactor, including the steps of:
- dynamically determining a level of density of a material to be compacted as a function of a number of passes over the material completed by the compactor, each pass corresponding to an increased level of density;
- determining a desired inflation pressure in proportion to the dynamically determined density;
- and
- adjusting the inflation pressure in response to the desired inflation pressure.
A method for controlling the inflation pressure of a set of tires on a pneumatic compactor, including the steps of:
- dynamically measuring a level of density of a material to be compacted;
- determining a desired inflation pressure in proportion to the dynamically measured density;
- and
- adjusting the inflation pressure in response to the desired inflation pressure.
