BACK PAVE
back pave is our new side paver concept. The machine combines excellent paving quality with high economy. As basic machine we use a standard wheel paver, which can also be supplied by the customer.

A reasonable modification and combination with our back pave –module converts the paver into a powerful machine with various fields of application in side paving. The concept allows the operation with hot mix in minimal and variable working widths assuring furthermore a high compaction with our back pave –screed. The basic machine can be built back any time into a standard asphalt paver.

Special Features
  • Using simple measures, the paver can be re-equipped so that the driver can work in the usual way but moving backwards. No major adjustments are required of the driver when working with machinery.

  • Due to the fact that paving takes place along-side the paver, optimal control of the
    paving process by the driver is made possible.

  • The paver is equipped with a signal light unit indicating green-red-green which assists communication with the driver of the material feeder concerning optimal influence when amending mixture conveyance.

  • 100 % insurance can be given that no material can drop in to the vicinity of the pavers path, due to horizontal conveyance of the paving material.

  • A balanced working condition of the paver is reached by ballasting the standard material hopper. Mixture conveyance from the feeder truck has no negative influence on the static performance of the under-carriage.

  • The push rollers to dock the truck on to the paver can be adjusted easily and so can be fitted on to the trucks.

  • A second horizontal auger serves to empty the far side paving material completely and to guide the paving material to the working side.

  • The material hoppers are shiftable and can be slid-in when the machine is being
    moved so that the working-width is around 2,5 m. The hopper can also be tipped up.

  • Regulation of layer thickness is supported via four hydraulic cylinders
    (two in the front and two at the back), enabling a very sensitive grade control
    resulting a level paving.

  • The same result can be achieved by paving with a levelling system of following variants: one sensor, two sensors or with a horizontal slope sensor.

  • The receptacle plate for screed installation is mounted on to the tension arm of
    working side. The screed can be adjusted with no allowance to required working width on a guide mandril. Besides the normal set-up, directional correction can be carried out – comparable to extension screeds – by using an associated hydraulic system.

  • By choosing torque and tamper-lifting set-up the operating performance of
    compression can be coordinated with the installed tamper compression aggregate.

  • The generator installed in the paver, powers the heating rods for tampers and
    screed plates.

  • In opposition to other pavers the side limitation of the screed is not static but can
    be moved, enabling reduction of the real working width to a minimal size
    (up to 15 cm) if required.

  • To ensure that the paving material is spread in front of the screed, even at high working widths, the material screed is supported by two hydraulically-driven paddles.
