EFFECT OF CHEMICAL COMPOSITION OF CRUDE OILS AND METHODS OF REFINING ON QUALITY OF SOUTH AFRICAN ROAD BITUMENS . 5TH CONFERENCE ON ASPHALT PAVEMENTS FOR SOUTHERN AFRICA (CAPSA 89). PROCEEDINGS HELD IN SWAZILAND, 5-9 JUNE, 1989

The physical properties of bitumens depend on both the source of crude oil and the refining process employed. Changes in either or both could lead to changes in the quality of bitumen produced resulting in a waste of funds due to road construction or maintenance failures. The crude oils received at one refinery and the bitumens produced from them have been monitored using a high performance liquid chromatography technique. The penetration grade bitumens were also physically tested and thin-film oven test residues chemically analysed. Results show that the major differences in bitumens arise from the refining process. The recommendation is made that a more comprehensive study be made into the effect of chemical composition of bitumens on their handling and setting properties. The chemical fractionation of bitumens by means of a high performance liquid chromatographic (HPLC) technique, is briefly outlined in an appendix. For the covering abstract of the conference see IRRD 828827.
