-
(University of Pretoria, 2018)The demand on South African railway freight lines is growing constantly with respect to train speeds and axle loading, thus increasing the forces and stresses experienced by the track structure. This may lead to rapid ...
-
(University of Pretoria, 2018)Mitigating the impact of electricity disruptions on water supply was investigated as a case study on the City of Tshwane. The case study was done based on a Risk Analysis and Mitigation Framework of Integrated Water and ...
-
(University of Pretoria, 2018)Within the corpus of accessibility measures is the Net Wage After Commute which describes the potential wage earnable less the transport costs incurred to commute to work from a particular location. This study examines the ...
-
(University of Pretoria, 2017)The performance of a railway track structure is significantly influenced by ballast shape properties such as roundness, flatness, elongation, sphericity, angularity and surface texture. Railway ballast materials have to ...
-
(University of Pretoria, 2013)Pavement layers are constructed using a combination of materials, of which rock aggregates constitute a larger proportion. Current understanding is that the performance of pavements is dependent on the aggregate shape ...
-
(University of Pretoria, 1993)The growing interest in pavement management systems (PMSs), both in South Mrica and internationally, has been in response to a shift in importance from the construction of new roads to the maintenance of the existing ...
-
(University of Pretoria, 2013)Structural engineers have used finite element methods for the design of reinforced concrete plate type structures for decades. The theory behind this method is well researched, however, there is still a lack of direction ...
-
(University of Pretoria, 1984)The initial utilization and calibration of the Dynamic Cone Penetrometer (DCP) for road pavement evaluation by the TPA Roads Department is discussed. The graphic representation of measurements are also illustrated. Following, ...
-
(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, 2009-08-04)The process of designing cementitious layers (weakly and strongly cemented) against fatigue distress in road structures is well accepted. Research and field investigations with the aid of the Heavy Vehicle Simulator (HVS) ...
-
(University of Pretoria, 1984)South Africa is a country fortunate in possessing a well developed network of paved roads that provides a basic and often overlooked facility for the social and economic welfare of the country. However, an accute shortage ...
-
(University of Pretoria, 2016)The study comprised the modelling of embankments on a heavy haul coal export railway line between Ermelo and Richards Bay in South Africa. The design of these embankments is usually done with slope stability analysis? ...
-
(University of Pretoria, 2015)Train speeds and heavy haul axle loads are constantly increasing the forces and stresses experienced by track structures. This is especially true for track transitions that generate high dynamic forces on both the track ...
-
(University of Pretoria, 2018)Conventional concrete road pavements are widely used and their behaviour is reasonably well understood and readily predictable, generally by means of semi-empirical design methods. An alternative pavement type, referred ...
-
(University of Pretoria, 2021)Bus Rapid Transit (BRT) systems have gained popularity worldwide as a cost-effective alternative to more expensive urban rail systems, carrying around an estimated 33 million passengers each weekday (https://brtdata.org/ ...
-
(University of Pretoria, 2018)A nation’s industrial growth as well as the quality of life is dependent on energy supply and demand. With the current situation of the supply of energy not matching the growing demand, small-scale hydropower projects ...
-
(University of Pretoria, 2022)The present study focuses on the condition monitoring of train wheels utilizing an 3D printed rail pad that is embedded with widely available accelerometers and a strain gauge. This smart rail pad was used on a heavy haul ...
-
(University of Pretoria, 2021)Recent tailings dam failures around the world have highlighted the real risk posed by undrained slope failures. Undrained failures are fundamentally different to drained failures in the sense that different mechanisms are ...
-
(University of Pretoria, 2023-06-01)The strengthening effect of matric suctions is typically ignored in slope stability analyses. This is due to the uncertainty in the magnitude and reliability of in-situ matric suctions and the effect thereof on the shear ...
-
(University of Pretoria, 2022)Plastic shrinkage cracking occurs in concrete members with large exposed surface areas, such as concrete pavements, bridge decks and floor slabs. Current research has shown that a notable increase in plastic shrinkage was ...
