Abstract

An acute-angled wedge, wider than pavement to be broken up and removed, is forced under the pavement to exert a force to lift it off the underlying ground. A heavy, pivoted, and preferably hydraulically driven hammer hits the pavement above the front edge of the wedge and cracks the pavement at every few inches of its length which then slides over the wedge and successive ramps to a second hammer. This second hammer, also preferably hydraulically driven, has a saw-tooth impact surface profile which renders the cracked pavement and any tensile reinforcement material therein into smaller pieces. These smaller pieces are collected into a hopper for periodic transfer to external transportation means, such as a front-end loader, for ultimate disposal. As pavement is removed and the apparatus moves on, the ground left in its trail is substantially in a condition to immediately receive replacement pavement.
