PD 6691 gives guidance on the use of BS EN 13108-1, BS EN 13108-4, BS EN 13108-5, BS EN 13108-8, BS EN 13108-20 and BS EN 13108-21. It includes general guidance and background information on BS EN 13108. Annex B provides guidance, based on the requirements formerly specified in BS 4987, for producing asphalt concrete that conforms to BS EN 13108-1; Annex C gives similar guidance, based on the requirements formerly specified in BS 594-1, for producing hot rolled asphalt that conforms to BS EN 13108-4; and Annex D provides guidance for producing stone mastic asphalt that conforms to BS EN 13108-5. This document does not give guidance on BS EN 13108-2, BS EN 13108-3, BS EN 13108-6 or BS EN 13108-7 as these are either little used in the UK or covered by other guidance.<\/p>\n
