(University of Pretoria, 2019)The soil-water retention curve (SWRC) is an essential tool in geotechnical engineering and agriculture used in the analysis of unsaturated soil conditions such as those found in tailings dams and the water retention ...
-
Traffic impacts of shared right-of-way public transport systems: A microsimulation-based case study (University of Pretoria, 2020)Bus Rapid Transit systems are becoming a more integral part of public transport systems in major African cities. Although BRT systems are more versatile than other public transport alternatives, they do require support ...
-
(University of Pretoria, 2020)The variability of the South African (SA) climate results in abrupt changes in river discharge rates. Compound weirs have been implemented as an attempt to ensure accurate discharge calculations over an extended, but ...
-
(University of Pretoria, 2019)Southern Africa is characterised as a region of moderate seismicity with several instances of both natural seismicity and mining-related seismicity occurring within the last century. Evaluating the performance of a ...
-
(University of Pretoria, 2019)In its white paper, the Department of Transport proposes a future South African core railway network which requires the conversion and construction of over 8,500 km of standard gauge railway track by 2050. The scale of the ...
-
(University of Pretoria, 2019)With the increased use of high performance concrete a lower water-to-binder ratio is employed to improve the properties of concrete and mineral and chemical admixtures are introduced. With a low water-to-binder ratio, ...
-
(University of Pretoria, 2020)The aim of the research is to investigate the effect of increased axle loading on saturated and unsaturated railway foundation materials for heavy haul applications. The research methodology comprises of a literature review ...
-
(University of Pretoria, 2020)The Soil Water Retention Curve (SWRC) of different soils has been researched thoroughly by multiple Geotechnical Engineers. The interpretation of the SWRC for a specific soil leads to the identification of certain properties ...
-
(University of Pretoria, 2020)In South Africa, as much as 33 million tons of ash, a waste product of burning coal, are produced per year. Of the total ash produced, just over 8% is sold for utilisation, the remainder of which is disposed of in landfills ...
-
(University of Pretoria, 2020-09-28)The mechanism of cave mining propagation still requires a better understanding to be attained outside the industry-accepted Duplancic conceptual model. While this model suggests a continuous damage profile to be followed ...
-
(University of Pretoria, 2021)The technical and economic feasibility of an inverted pavement has been proven abroad and in Brazil, but there are still doubts relating to the parameters that may affect the performance of this type of pavement, particularly ...
-
(University of Pretoria, 2020-12-31)The focus of this study is to gain a better understanding of the hazards affecting the transportation of avocados from farm to packhouse by developing an effective risk assessment tool farmers can use. The transport related ...
-
(University of Pretoria, 2020)Ultra-Thin Continuously Reinforced Concrete Pavement (UTCRCP) is an innovative pavement type that has the potential to fulfil South Africa’s pavement repair strategy requirements. It consists of a 50 mm thick High Strength ...
-
(University of Pretoria, 2019)The delivery of medium and mega project has been a challenge for a number of decades, with attempts made to reduce the associated issues around engineering projects implementation. Project delivery before 1950 mainly relates ...
-
(University of Pretoria, 2019)In November 2016, 38 sinkholes formed due to subsurface erosion above undermined ground on Donkerhoek farm near Sasolburg. The fact that the sinkholes formed more than 24 years after mining in the area ceased, emphasised ...
-
(University of Pretoria, 2019)The minibus taxi industry has grown from a modest provider of public transportation to the largest supplier to the urban public. Attempts have been made by government to regulate, integrate, and upgrade this sector but ...
-
(University of Pretoria, 2020)Investigation into the causes of Platform Train Interface (PTI) occurrences has led to the conclusions that PTI occurrences can be attributed to human factors and platform design. In South Africa, PTI occurrences account ...
-
(University of Pretoria, 2019)The disposal of fly ash into landfills is quickly becoming a cause of environmental concern. At the same time the construction industry urgently needs sustainable materials with reduced environmental impact. Alkali-activated ...
-
(University of Pretoria, 2020)Pile foundations are extensively used to support various structures that are constructed in soft/loose soils, where shallow foundations would be considered ineffective due to low bearing capacities and large settlements. ...
-
(University of Pretoria, 2020)The overall objective of this study was to develop an optimised Ultra-High-Performance Concrete (UHPC) matrix based on the modified Andreasen and Andersen optimum particle packing model by using available South African ...
