Abstract
A paving machine forms aqueduct channels using a screed assembly having elongated forming arms, and deposits pavement material onto these arms. As the machine advances, channels are formed in the pavement layer. This results in a porous pavement material having a number of aqueduct channels formed underneath the pavement surface, so that water can percolate downward into the pavement and enter the channels.
