Preparations for paving dual-layer concrete: The bottom-layer paver - an SP 1500 - needs extremely little space for turning.
The top-layer concrete is delivered over and across the bottom- layer paver to behind the central tie bar inserter.
The bottom-layer paver is inserting dowel bars and central tie bars into the concrete at precisely the specified height in an automated operation.
The top-layer concrete paver is placing the concrete pavement to the specified evenness, followed by a burlap which produces the desired surface texture.
