Installation Notes on the Challenge of Anchoring to Asphalt: Asphalt is gravel held together with oily pitch ("Bitumen"). Unlike concrete, asphalt will yield to forces applied for extended amount of time. For this reason, the common expansion anchors (which are used on concrete) can not be used for fastening to asphalt. Any expansion anchor installed in asphalt will loosen and fail within days.
