(University of Pretoria, 2019)Approximately a quarter of South Africa’s Gauteng Province is underlain by dolomite, a carbonate rock which is susceptible to dissolution and therefore sinkhole formation. Current design codes for developing on dolomitic ...
-
(University of Pretoria, 2018)Concrete structures are subjected to complex and highly variable climatic conditions including temperature, wind speed, rainfall, and solar radiation. The thermal behaviour of concrete structures has become an important ...

-
(University of Pretoria, 1988)Afrikaans: Hierdie verhandeling vorm 'n dokument waarin riglyne met betrekking tot die antwerp van grand- en rotsvuldamme (vuldamme) vir Suid-Afrikaanse toestands saamgestel is. Bestaande kennis is gerntegreer en saamgevat. ...
-
(University of Pretoria, 2019)At first glance the operational performance of ballast appears trivial in its simplicity. However, various mechanisms affect the short and long term performance of the ballast and in turn, the response of the track structure, ...
-
(University of Pretoria, 2018)Permanent deformation (rutting) is a pavement distress condition visible in the surfacing layer of a pavement. It occurs along the wheel path and results from the accumulation of load-induced permanent deformation developed ...
-
(University of Pretoria, 2018)The addition of discontinuous discrete fibres to concrete has repeatedly been shown as an effective method to overcome the inherently brittle nature of concrete. The resulting composite has enhanced toughness and impact ...
-
(University of Pretoria, 2019)The use of short, randomly distributed fibres in reinforcing concrete has led to improved durability and ductility, the latter of which is a key characteristic in the redistribution of moments. Steel fibres can be specified ...
-
(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, 2018)Laboratory tests on ballast give insight into the behaviour and performance of the ballast layer under passenger and heavy haul traffic. It is important, however, to ensure that the simulation of train loads on the ballast ...
-
(University of Pretoria, 2018)The United States Environmental Protection Agency (USEPA) has enlisted phenolic compounds as pollutants of priority concern, as they tend to persist in the environment over a long period, accumulate and exert toxic effects ...
-
(University of Pretoria, 2018)One of the most common hydraulic risks on a pavement surface is the accumulation of surface runoff caused by insufficient surface drainage. As the water depth on roadway surface increases, the risk for hydroplaning and ...
-
(University of Pretoria, 2018)Railway wheel squeal is an unresolved noise challenge facing the railway industry. Of all the noise sources originating from railways, tonal curve squeal is one of the loudest and most disturbing. Wheel squeal results from ...
-
(University of Pretoria, 2019)Ultra High Performance Concrete (UHPC) is an ultra-high strength concrete with superior mechanical properties. The high compressive strength (more than 150 MPa) and high ductility make UHPC a suitable material for manufacturing ...

-
(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, 2017)Civil structures are founded on or within soil. Understanding the interaction of a structure with the soil it is founded on or within is vital for designing and constructing structures that will be safe and functional for ...
-
(University of Pretoria, 2018)Changing climatic conditions worldwide are causing a change in moisture conditions of railway formations and slopes, thereby either strengthening or weakening them. Current railway formation design methods do not take ...
-
(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 ...
