  • Nedbank Capital Expenditure Project Listing 2019
    CAPITAL EXPENDITURE PROJECT LISTING 1 January 1993 to 31 December 2019 NEDBANK GROUP ECONOMIC UNIT 11 February 2020 NOTES: Definition: The schedule is a listing of capital projects announced in the Republic of South Africa. It includes: • Only projects valued at R20 million or more. • Projects of an expansionary nature, i.e. capex which allows for an increase in the level of output, rather than pure replacement investment which involves the replacement of worn-out or outdated capital goods necessary for the continued operation and the maintenance of current output levels. The exceptions are: • investment in equipment or machinery which reduces the harmful effects of pollution, and • technological upgrading of equipment and machinery. • Projects funded by both the private and public sectors. • Projects reflecting direct foreign involvement. The listing is compiled on a sectoral basis, conforming to the Standard Industrial Classification. Limitations: Any analysis of the data needs to take account of the limitations outlined below: • The schedule highlights significant areas of investment expenditure and not the absolute total value of all capital investment undertaken in the country. It serves as a rough guide to the general direction in which investment is moving and as an indication of the level of confidence in the economy. • The full extent of replacement capital expenditure is not captured as mainly expansionary capital expenditure are published and recorded. • In certain sectors a reliable indication of investment activity is not possible as typical investments are not large enough to be included in the schedule, even though the total capital expenditure in the sector may be substantial.

  • Gb5® High Modulus Asphalt
    GB5® HIGH MODULUS ASPHALT DJ DE BEER Much Asphalt, 200 Coedmore Road, Bellair, Durban 4006. Tel: 0823355041, Email: [email protected] ABSTRACT With ever increasing volumes of traffic on South African roads, and particular that of heavy vehicles, the road building industry has recognized the need for specialised asphalt mixes to address the rutting and fatigue problems experienced currently. GB5 is a cost effective asphalt base mix, designed for high performance and long life, similar to stiff grade bitumen mixes (EME’s). This mix can be produced with most of the aggregate and bitumen road grade types available in South Africa that is currently being used in the production of hot mix asphalt. Usage of this mix will allow for reduced pavement thickness, increased longevity and decreased rutting. The GB5 alternative controls the volumetric properties by optimizing the combination of fine and coarse aggregates, resulting in an interactive network of particles in the mix to obtain a high stiffness modulus; at the same time uses modified bitumen, instead of high binder contents to obtain good fatigue properties. GB5 has already proven itself in France, where it was developed, under heavy traffic (more than 500 000 tons paved) where legal axle loading limits are significantly higher than those in South Africa. The extensive trials done in eThekwini Metro in KZN have shown that the GB5 technology has now successfully been transferred to South Africa. BACKGROUND The need for asphalt base and surfacing mixes that can perform well without premature rutting or cracking under extreme loading led to research worldwide into stiffer, stronger layers.
