Roads are expensive and use a lot of raw materials to construct. But few people realise that our blacktops are completely recyclable - and re-using asphalt, as well as other waste materials, to build new roads will save South Africa a great deal of money and precious resources, writes Trevor Distin, CEO of the Southern African Bitumen Association (Sabita).
SSI Engineers and Environmental Consultants in joint venture (JV) with Asch Consulting Engineers have entered the construction supervision phase of a multi-million contract awarded by the South African National Roads Agency Limited (SANRAL) for the design and supervision of three hi-tech traffic control centres in Limpopo Province.
Perrie (52) is regarded as one of South Africa's top authorities on concrete pavements and is internationally held in high regard for his expertise in this field. He is the C&CI's concrete roads project leader and was also, prior to his new appointment, technical manager of the Institute.
Several engineers have had a lasting influence on the well-being of Cape Town - one thinks of Stewart, Lloyd-Davies, Shand and Morris - but few have been as influential as Sir John Coode. It was his plan for the progressive development of the Table Bay Harbour complex which eventually led to the reclamation of the foreshore and thus doubled the effective area of the CBD. Coode also made a huge contribution to the development of the harbours at East London and Durban and had a hand in the design of most other South African ports.

A worldwide resurgence of interest in Rail transportation as a result of the energy crisis and increasing road traffic congestion is examined. The need for close co-operation between transport and town and regional planners is emphasized. Radical changes in our mode of living appear inevitable and forward planning to meet these changes must be started immediately while time and opportunity are still available.
