TLDR
A revolving paddle mixer for re-mixing a hot asphalt mix deposited in the hopper of a road paving machine is described in this paper, where the mixer takes the form of a plurality of paddles angularly positioned relative to each other and mounted on a revolving shaft adjacent to the conveyor for transporting the asphalt mix material to the rotating auger.Abstract:
A revolving paddle mixer for re-mixing a hot asphalt mix deposited in the hopper of a road paving machine The mixer takes the form of a plurality of paddles angularly positioned relative to each other and mounted on a revolving shaft adjacent to the conveyor for transporting the asphalt mix material to the rotating auger The resultant re-mixture is more uniform and dense so that a smooth pavement is laid on the roadwayread more

Additive injection device for paving machines
TL;DR: In this paper, a device for applying a mat of aggregate material having an entrained liquid additive as the device is moved along a path is described. The device includes a hopper for receiving aggregate material, a spreader for spreading aggregate material generally transversely relative to the path, a compacting screed for compacting the aggregate material into the mat, and a mixing conveyor arranged to convey the aggregates from the hopper to the spreader and to mix the aggregate materials along the length of the conveyor.
