GeneralQ I am working on an existing slope with a ratio of 3:1 (horizontal:vertical) and a total height of 6 ft (1.8 m). The slope has been surfaced with asphalt concrete. Will shotcrete adhere to the asphalt concrete surface, or should the asphalt concrete be removed prior to applying shotcrete?
Shotcrete will adhere to properly prepared asphalt concrete. Shotcrete bond is generally related to the preparation of the surface that you want to bond with. If the surface is dirty, the shotcrete will not bond very well.
