MEETINGS AT TYLOESAND 8-9 JUNE 1976. QUALITY CONTROL FOR HOT MIX PLANTS

FOERHANDLINGAR I TAYLOESAND 8-9 JUNI 1976. PRODUKTIONSKONTROLL VID TILLVERKNING AV ASFALTMASSOR

The meeting dealt with the following subjects: (1) research and development in 1975-76, (2) proposals for new asphalt specifications in the Scandinavian countries and the main subject, (3) quality control for hot mix plants. A Swedish report comprising a questionnaire to the producers of asphalt mixes gave the following results: (1) All the mixing plants in operation practised some kind of quality control in 1975, involving a continuous examination of the mixes produced. (2) The mixing plants are divided into three groups according to which category of purchaser had been the largest regarding deliveries from the plant. There was no noticeable difference between these groups in the organization and extent of the quality control. (3) The costs of the quality control varied between sw.crs. 0.25 and 2.00 per ton asphalt mix produced. The average cost was about sw.crs. 0.70 per ton mix. The comments of the other countries showed that there is a certain disagreement regarding the method of carrying out the quality control and its purpose. However, agreement was reached that from the economic standpoint quality control can give a positive result in a higher quality of the finished pavement. A condition for this is that sampling, analysis and judging of the results of the analysis take place in a suitable way. /TRRL/
