Abstract: The present invention provides improved paving vehicles for following a supply truck for use in paving asphalt roadways. The paving vehicles of the present invention need not be transported on a trailer, and are capable of traveling at low or relatively high speeds on their own. This is accomplished through the use of novel chassis and propulsion systems having two rear axles, with each axle coupled directly to its own hydraulic motor, such that each of the two hydraulic motors provides power to one axle. Embodiments of the invention also include reciprocating conveyor apparatus and methods, such that the conveyor apparatus may be moved to a lowered position to receive the gravity discharge of materials from a hopper and supply truck during a paving operation, and moved to a raised position in order to provide a wide margin of ground clearance when driving the paving vehicle, or loading or unloading the paving vehicle from a trailer.

The wear element and piston may be urged inwardly in response to an applied load at the drill bit gauge pad, increasing the lateral depth of cut and thereby controlling the aggressiveness of the bit in response to the load.
