Modelling of the transport of fine cohesive sediments, as found in most South African reservoirs, has not been well developed. This is because the transport processes that are involved are complex and the theories not ...

ENGLISH ABSTRACT: Accelerated pavement testing (APT) is the application of a wheel loading, to a prototype or actual layered, structural pavement system to determine pavement response and performance under controlled, ...

ENGLISH ABSTRACT: A number of studies have acknowledged the positive impacts that rural roads have on the social and economic development of a region. This impact is due to the increased accessibility offered by road ...

ENGLISH ABSTRACT: Roberts splitters have effectively been used for more than 75 years to dissipate the flood discharge energy of more than 30 dam spillways in South Africa and abroad. Roberts’ (1943) standard, unaerated ...

ENGLISH ABSTRACT: The age-related performance of typical seal binders in South Africa was studied to understand the behaviour of the binders as it ages. The three main failure mechanisms for surfacing seals include surface ...

ENGLISH ABSTRACT: Most of the parameters involved in the design and analysis of structures are of stochastic nature. This is, therefore, of paramount importance to be able to perform a fully stochastic analysis of structures ...

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 ...

ENGLISH ABSTRACT: In the construction of multi-storey buildings, the reinforced concrete (RC) core or shear walls normally precede the construction of the RC floors. A system is therefore required to connect the floors ...

ENGLISH ABSTRACT: Environmental issue effects like natural resource depletion, climatic change and global warming have significantly influenced the innovations in material science and technology with the aim of attaining ...

ENGLISH ABSTRACT: A road safety remedial programme has as an objective the improvement of road transportation safety by applying road safety engineering remedial measures to hazardous road network elements in a manner ...

ENGLISH ABSTRACT: The scour mechanisms of rock are highly variable, equally so the geotechnical and hydrodynamic conditions of each study area, which complicate the prediction of scouring. Cases such as Kariba Dam and ...

ENGLISH ABSTRACT: Tubular Modular Track (TMT) is a relatively new rail design invented in 1989. The system is ballastless and is designed to continuously support the rails on twin reinforced concrete (RC) beams which are ...

ENGLISH ABSTRACT: This report deals with the use of Doppler meters to measure flow velocities and hence discharges in streams. The Doppler meter measures the shift in frequency of an acoustic wave, which it emits and ...

ENGLISH ABSTRACT: The intent of this thesis is to examine the solving of problems with neural networks. Three cases are investigated: the calculation of a Visual Condition Index (VCI), the determination ofthe reseal need, ...

ENGLISH ABSTRACT: In this study the numerical short wave model SWAN is evaluated for application to a selected coastal region in South Africa. The aim of this study was to evaluate the degree of accuracy with which SWAN ...

ENGLISH ABSTRACT: Support tower structures of Wind Energy Conversion Systems (WECS) are major cost items and by means of integrated design and optimization, the Life-Cycle Cost (LCC) can be reduced substantially. In this ...

ENGLISH ABSTRACT: The design and construction of an appropriate vertical seawall/breakwater is an important part of an engineering project since the incident and reflective wave forces acting on the vertical seawall cause ...

ENGLISH ABSTRACT: Stepped spillways have been used for approximately 3500 years and, with the recent technical advances in Roller Compacted Concrete construction, these spillways have received a renewed interest over the ...

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 ...

ENGLISH ABSTRACT: Labour based technology has extensively been utilized in delivery of poverty alleviation programmes. Most of the projects implemented have been of construction in nature. In many cases, labour based ...
