Thesis (Ph.D. (Engineering))--University of the Witwatersrand, Engineering Faculty (Civil Engineering), 1977 / The thesis deals with the development of improved road tarbinders in
South Africa and their application in surface treatments and in mixes
used for pavement wearing courses and base courses in this country.
This work is timely in view of the country's current economic problems.
Locally produced tarbinders are considerably less expensive than bitumen
binders in inland areas; tar being produced in the Witwatersrand
complex whereas locally refined bitumen is produced from imported crude
oil. The annual expenditure on bitumen by the South African road industry
is currently of the order of R26 000 0 0 0. However, previously it had
been found that tarbinders were less durable than bitumen. [Abbreviated Abstract. Open document to view full version] / WS2017
