A warm mix asphalt plant comprising a counter-flow drum, apparatus for precisely metering flows of A/C and water, an asphalt expander with no moving internal parts where a circular curtain of flowing clean water is mixed with a coaxial circular curtain of moving heated A/C to create asphalt foam which is heated and mixed inside a lower portion of the asphalt expander and then distributed to cover aggregate inside the counter-flow drum.

Warm mix asphalt production system and method

An asphalt paver for applying a mat of asphalt material as the paver is moved along a path includes a frame, a compacting screed having rotatable vibrator shaft, and an edge compactor attached to the outer end of the compacting screed. The edge compactor includes a pivoting nose piece or tamping bar having an outer end generally overlying an edge portion of the asphalt mat, a rotatable shaft connected to the vibrator shaft, and a rod eccentrically mounted to the rotatable shaft and secured to the tamping bar outer end for pivoting the tamping bar in response to rotation of the rotatable shaft. The oscillating movement of the tamping bar over the outer edge of the asphalt mat compacts the edge of the asphalt mat as the paver is moved along the path.
