In a spreading apparatus for scattering spreading material, in particular sand or soil substrates, onto a ground surface, includes a container for the spreading material and at least one spreading unit by which the spreading material in the container can be scattered, wherein the spreading unit includes at least one rotatable spreading disc which is substantially parallel to the ground and at least one drive device for rotating the spreading disc about the axis of rotation with the result that the spreading material can be scattered by the spreading disc and by virtue of centrifugal forces, provision is made for a limiting device to be arranged in at least part of the circumferential region of the spreading disc, which limiting device prevents the scattering of the spreading material in this part of the circumferential region, wherein the position of the limiting device relative to the spreading disc is adjustable, with the result that the direction in which the spreading material can be scattered is variable.

An asphalt paving system comprising a plurality of dispensing shafts and a plurality of rolls of pavement reinforcing membrane. The plurality of dispensing shafts are adapted to be mounted on an asphalt paving machine, where at least a portion of at least one dispensing shaft extends from at least one side of the paving machine, and at least a portion of at least one dispensing shaft extends to a front of the paving machine. Each roll of pavement reinforcing membrane is supported by one of the plurality of dispensing shafts. As the asphalt paving machine moves, the plurality of dispensing shafts dispense the pavement reinforcing membrane continuously beneath the asphalt paving machine and the hot asphalt material is dispensed from the hopper on top of the pavement reinforcing membrane beneath the asphalt paving machine.

A frozen precipitation treatment system in the form of a spreader assembly may be used with a video monitoring system. The operator within a vehicle passenger compartment may manually view a display screen to see video images within the hopper to visually assess the amount of frozen precipitation treatment material within the hopper in real time.

The present invention is directed to an improved design and improved method of installation of stress absorbing membrane interlayers, commonly known as SAMIs, used for strengthening and waterproofing asphalt pavements in road or highway surfacing operations. By a novel method of modifying a standard paving machine the present invention makes it easier and more convenient to install SAMI membranes beneath a layer of new asphalt pavement, thus providing greater resistance to pavement cracking resulting in lower overall maintenance costs.
