Paving

Paving is done with a slipform paver traveling in continuous placement. The starting point of this placement is a ragged edge, which is later cut away with a slab saw. The finishing point is the same. The Bunyan Striker is used to connect the slabs in a plug, which is similar to a bridge approach. The Bunyan Striker is popular because a quick setup can provide powerful control of surface grade in a low slump placement of irregular shape.

This is also very useful in ramps of irregular shape. The slipform paver will not configure to edges which are not parallel. The Bunyan Striker allows operators to switch to a longer tube as the slab becomes wider.

Some highway builders choose to use the Bunyan Striker as a straightedge carried upon the mullboards of the slipform paver. This verifies the accuracy of the slipform paver and provides a way to fix the errors, which may occur. Some find this useful in satisfying inspectors at the output of the slipform paver as well as measures against surface grinding.
