Age-related performance of typical seal binders in South Africa
(Stellenbosch : Stellenbosch University, 2018-03)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 ...
-
Algorithmic component and system reliability analysis of truss structures
(Stellenbosch : Stellenbosch University, 2013-12)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 ...
-
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 ...
-
Alternative Wall-to-slab Connection Systems in Reinforced Concrete Structures
(Stellenbosch : Stellenbosch University, 2016-12)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 ...
-
Analysing the Behaviour of Soil Reinforced with Polyethylene Terephthalate (PET) Plastic Waste
(Stellenbosch : Stellenbosch University, 2016-03)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 ...
-
The analysis of road traffic accident data in the implementation of road safety remedial programmes
(Stellenbosch : Stellenbosch University, 2001-03)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 ...
-
Analysis of the Hydrodynamics of rectangular plunging Jets and the subsequent scouring in broken-up Rock Beds
(Stellenbosch : Stellenbosch University, 2016-03)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 ...

Analysis of the transition between Tubular Modular Track and ballasted railway
(Stellenbosch : Stellenbosch University, 2016-03)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 ...
-
The application of Doppler velocity meters in the measurement of open channel discharges
(Stellenbosch : Stellenbosch University, 2001-12)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 ...
-
Application of neural networks in pavement management
(Stellenbosch : Stellenbosch University, 2000-03)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, ...
-
The application of the numerical wind wave model SWAN to a selected field case on the South African coast
(Stellenbosch : University of Stellenbosch, 2002-03)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 ...

Applying geographic information systems to delineate residential suburbs and summarise data based on individual parcel attributes
(AOSIS Publishing, 2013)Background: Information aggregation to suburb level is of interest to engineers and urban planners. Readily available suburb boundaries do not always correspond to the suburb names recorded for individual properties in ...
-
An approach to multi-objective life cycle cost optimization of wind turbine tower structures
(Stellenbosch : Stellenbosch University, 2013-12)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 ...
