ABSTRACT The primary objective of this work is to form the foundation of a Road Management Maintenance System (RMMS) that Road Maintenance Agencies like FERMA can immediately implement to make better decisions pertaining to rehabilitation options. Further, this is to allow for appropriate decisions about the best type of maintenance and rehabilitation interventions to apply to the poor state of arterial roads taking into consideration various factors, least of which are the type and ext...
ABSTRACT Abakpa-Nike is notorious for chaotic traffic due to driver's indiscipline and poor road nehvork. This study was therefore undertaken to determine the level of traffic congestion at four major intersections: The Abakpa-Nike- Trans-Ekulu T-Junction; Abakpa-Nike Liberty Junction; Afia Abakpa Junction and Nowas Roundabout Intersection in Abakpa-Nike area of Enugu, Enugu State. These intersections are notorious for high traffic volumes. Vehicular traffic volume were measured to quantify o...

ABSTRACT This dissertation examined and presented adaptive water governance analysis and tools for the Upper Swakop Basin (USB) in Namibia where integrated river basin management is still in its infancy. The water governance concerns in the basin include pollution monitoring and control challenges that are further threatening the security and adequacy of the developed drinking water sources. By applying and triangulating different methods (models, statistical analysis, quantitative and qualit...
ABSTRACT The City of Cape Town is the most congested city in South Africa, with Johannesburg coming in second. Capetonians are spending 75% more time in traffic because of the congestion during peak hours, thus reducing time spent on leisure and other activities. Due to population growth, increasing car ownership and declining capacity of rail infrastructure, Cape Town’s road infrastructure will continue to be under severe pressure if the status quo is maintained. Research shows that conges...
Soil materials are a vital element in all civil engineering designs hence the first step in any geotechnical engineering project is to identify and describe the soil condition if not suitable, disposal or stabilization of the soil should be carried out . In lieu of these, this research was carried out to study the effects of coconut waste ash (CWA) derived from open uncontrolled burning on lime stabilized A-7-5 soil for road construction. Natural soil was collected from a borrow pit location ...
This paper discusses the recent investigation into the composite action of pultruded Fibre Reinforced Polymer (FRP) and concrete hybrid systems, under static push-out tests. The study sought to experimentally determine the characteristic load-slip behaviour of the FRP-concrete composites under varying shear stud arrangements and failures modes associated with the variations and the push-out load capacity. For the initial tests, three composite test specimens were fabricated using FRP wide fla...
ABSTRACT Soils containing large quantities of clay and silt are the most burdensome to the engineer. These soils exhibit marked changes in volume with changes in water content and consequently affect the function of any layer lain upon it due to its shrink and up heave behavior when used as a subgrade or a layer built of it. The test assesses the geotechnical characteristics of silty clay soil in order to increase the shear strength and decrease the compressibility of the soil, so that the b...
Since the inception of the Private Finance Initiatives (PFI) in the United Kingdom, Government are increasingly adopting it as a means of proving infrastructure to the public neglecting the traditional procurement methods which relies completely on the public finance. Private Finance Initiative (PFI) is a method of contract procurement where the private organisation provides an infrastructure, finances, operates and maintains the infrastructure. This is done by transferring the risks involved...
