Abstract
The present device is a rumble strip forming apparatus for reducing the amount of reactive force transferred to the transporter. The rumble strip forming apparatus includes a transport, a lift device, a grinder, and a drive means that connect drive portions of the transport to the grinder to synchronize engagement of a cutting device with the pavement with forward movement of the transport while providing rearward movement of the grinder drum during cutting. The grinder is configured to provide both rotation of a pavement cutter and up and down movement of the pavement cutter while portions of the grinder remain in contact with the pavement.
