Quality Assurarice and Functional Demands

Quality a.curance and functional demands are taken more and more into account in contracts for road construction. This paper describes a contract for a 15 km long concrete pavement for a motorway in West Sweden. Functional demands were chosen for wear resistance, evenness, tensile strength, thickness, frost resistance, surface friction, aggregate exposure and freedom from cracks. This paper also describes how the contractor worked with the quality scheme, the procedure and the specific quality assurance programme for the project. The test methods are important and have to be very fast to apply the results directly to the production. Some new testing methods are presented. The organization and co-operation are also veiy important for a good result.
