Towards the development of a standard test protocol : application of the MMLS3 for evaluating the performance of surfacing seals
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: For a road to perform optimally, both functionally and structurally; a durable, waterproof, skid-resistant, all-weather and dust-free surfacing is required to provide the road user with an acceptable level ... -
Shoreline changes and longshore transport at the Port of Ngqura
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: The fixed sand bypass system at the Port of Ngqura was designed to match the natural longshore transport rate. Several factors, such as natural pebble presence and pump downtime, have resulted in the bypass ... -
Self-compacting concrete versus normal compacting concrete : a techno-economic analysis
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: Self-compacting concrete (SCC) also referred to, as self-consolidating concrete, is a relatively new concrete technology used in the construction industry. It is able to flow under its own weight and ... -
Seismic evaluation of the north bound N1-R300 bridge interchange
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: The N1 / R300 or Stellenberg interchange was designed in 1982 and construction was completed in early 1986. The bridge was designed according to the Code of procedure for the Design of Provincial Bridges ... -
The reliability of weight optimised steel portal frames
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: Steel portal frame structures are traditionally designed in accordance with ultimate limit state criteria and then typically evaluated in terms of the serviceability limit state. The serviceability limit ... -
Modelling of slotted bolted friction connections as seismic energy dissipaters in braced steel frames
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: The Slotted Bolted Connection provides additional energy dissipation during seismic loading, which leads to a reduction in structural damage. The effects of past earthquakes have shown that braced steel ... -
Loading, modelling and costing of concrete and steel support structure designs : large wind turbines in South Africa
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: Wind energy has the potential to be a strong contributor to a more sustainable future. Globally it is a major player in the market and is expected to become more influential in the future. In South Africa ... -
Investigation of factors affecting the load carrying capacity of driven solar panel support posts
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: A number of large “solar farms” have already been built in South Africa and more are under construction. Many of these make use of banks of photovoltaic panels mounted on a frame-work supported on columns ... -
Investigation of air concentration and pressures of a stepped spillway equipped with a crest pier
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: The evolution of roller compacting concrete has led to stepped spillways becoming increasingly popular over recent decades, mainly credited to the fact that the stepped profile of the downstream dam ... -
An interactive construction deployment planning model for the SKA project
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: The Square Kilometre Array (SKA) is a global project to build the world’s largest telescope that stretches over at least 3000 km. There is a number of factors that need to be considered during the planning ... -
Geotechnical properties and foundation requirements for the Satellite and Lunar Laser Ranger at the Matjiesfontein Space Geodesy Observatory
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: The basic idea of Satellite and Lunar Laser Ranging (S/LLR) is to improve our understanding of gravity. The earth-moon system is a good workspace to test the theories of gravity. By measuring the ... -
Fatigue performance of seals
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: Thin bituminous surfacings, in particular sprayed seals, are used quite extensively in various countries because they provide a low cost alternative to conventional asphalt. Seals furthermore provide an ... -
The effect of macro-synthetic fibres on the drying shrinkage cracking behaviour of concrete slabs on grade.
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: Slabs on grade are the most commonly used floors for the ground floor of structures without basements. These slabs are made from the generally used construction material called concrete. Concrete is ... -
Bond behaviour of deformed steel reinforcement in lightweight foamed concrete
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: Lightweight foamed concrete is a low density concrete that utilizes the entrapment of air generated from a protein based foam mix constituent. It is produced with the base constituents: water, cement ... -
The aspect of labour in hybrid and in-situ concrete construction in South Africa
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: Hybrid concrete construction (HCC) is a construction technique that makes use of both in-situ and pre-fabricated concrete products by making optimum use of the advantages of both these methods in the same ... -
Alternate methods to determine the microstructure of collapsible soils
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: Collapsible soil is one of the most widely distributed problematic soils in the world including South Africa. Extreme leaching and erosion of the colloidal matter and fine particles creates a structure ...
