This Supervision Manual will be incorporated in existing Danish Road Standards and as such will be a part of future contract material. The Supervision Manual has been prepared by a working group with the representatives from the Road Authorities, the Asphalt Industry and the National Road Laboratory. Modern quality management principles (e.g. as stated in the ISO-9000 series) attaches importance to planning and process management instead of subsequent control. The contractor should therefore to the greatest possible extent ensure and document the quality as an integral part of the production. Importance is attached to effective interplay between the quality management of the client's supervision and the contractor's supervision (own control).
