    A comparison of design and actual traffic levels and its likely impact on the pavement premature failure : case study of Gulu – Atiak – Nimule Highway
    (Makerere University, 2024) Komakech, Henry
    The Gulu-Atiak-Nimule highway was constructed and completed to a flexible pavement standard in the year 2015 and opened to traffic that traverses this highway from mainly Kenya, Tanzania via Uganda to South Sudan. The anticipated increase in traffic volumes and especially heavy axle load trucks might have brought the road pavement to a premature failure. The road is currently short of its structural capacity, highly distressed and showing signs of failure. This is affecting the flow of traffic and increasing operational costs coupled with the fact that a number of accidents have been reported resulting from a number of distresses such as potholes, cracks, edge shoulder drops, rutting, ravelling, and failed sections of the road. This research study involved carrying out traffic surveys, axle load surveys and road condition assessment surveys. The traffic surveys involved manual classified seven consecutive day count for 12 hours and 24 hours. The 24-hour count was carried out for 2 days, with 1 day within the week and 1 other day within the weekend. The axle load survey was done at the fixed weighbridge at Elegu near the South Sudan boarder. The condition assessment was undertaken using the ASTM D6433 method that involved visual inspections and recording of distresses observed on the pavement surface and qualifying them. Results from the study indicated that the current Average Daily Traffic (ADT) and Average Annual Daily Traffic (AADT) are 2604 and 2939 Vehicles per day respectively. Heavy traffic alone consisting of mainly truck trailers and semi-trailers constituted 29% of the total traffic volume. The Cumulative Equivalent Million Standard Axle for the year 2024 was calculated and obtained as 1.285million ESA which is a T3 Traffic Design Class. The comparison of these volumes to that considered at design reflected a traffic growth rate of 14% and yet that at design, the growth rate was taken at 6% per year for the first 10years. The axle load survey results indicated that the average weigh of heavy traffic was 43.025tons and this generated a damaging factor to the pavement of 2.973. The pavement condition evaluation carried out, indicated that the Pavement Condition Index and International Roughness Index for the Gulu–Ataik sectional link was 38 and 4.0m/km respectively; while that of Ataik –Nimule section registered PCI and IRI of 64 and 3.5m/Km respectively. This study has revealed that the current traffic volume is high totalling to 2604vpd, with 29% of this being attributed to heavy traffic and therefore increased million standard axles. The section from Gulu–Ataik was in a poor condition and hence required rehabilitation to further extend the pavement life; while that of Atiak-Nimule was in a fair to good condition and required routine maintenance.

    Land eviction risk analysis on Mailo land tenure system in Uganda; a case study of Kasambya Subcounty-Mubende District
    (Makerere University, 2022-02-04) Ngobya, Daniel
    Access to secure land and housing is a precondition for reducing poverty, yet many millions of people live under the daily threat of eviction, or without sufficient security to invest what they have in improving their homes. Looking at the cases of evictions which have taken place in Uganda, most of the people evicted happen to be bona fide or lawful occupants (Bako, 2009). Despite all the resources invested by government, land evictions on Mailo Land tenure have continued to manifest. This can partly be attributed to lack of a GIS based land eviction risk analysis of communities where scarce resources and interventions can be invested by decision makers and appropriate actions taken. Therefore, this study aimed at carrying out a land eviction risk analysis in Kasambya Sub County, Mubende district. The specific objectives of this study included; a) To determine the causes of land evictions on Mailo land tenure. b) To develop a land eviction risk map for communities within Kasambya sub county, Mubende district. Factors that influence the land evictions were reclassified, given weights through pairwise comparison and overlaid to identify villages that are at risk of being evicted from the land. It was found out that villages near the Kasolo central forest reserve were at the highest risk of being evicted. This research recommends use of evidence-based interventions that can be taken by decision makers to control evictions.

    Field industrial training in construction of a Solar Powered Deep Production Borehole System for safe water supply in Kikumbo Parish Kirugu Sub county
    (Makerere University, 2020-12-21) Nyerinde, Frank Nahurira
    This industrial training report comprises of the activities I participated in, I had hands on, carried out and observed while I was on my industrial training from January to June 2020. I took to myself all the work events, procedures of the work done and observed all were recorded in the daily note book and used to compile this report The construction of Kyambura Hydro Power plant in Kirugu Sub-county, Rubirizi District has had a wide range of effects on the communities within the project belt and the neighboring areas. One of such effects is accessibility to water, especially for domestic use. Whereas the majority of the community members used to fetch water form River Kyambura, this was affected by the alterations made on the river by the power project. Currently people from Kaberengye A, Kaberengye B and Omukabare A communities use unsafe water from River Kyambura carried in trucks to their villages and other members use water from other stagnant and unclean sources, which expose them to diseases like bilharzia, typhoid, cholera, diarrhoea and other water-borne diseases. Other members walk long distances of up to 5 kilometres to fetch water from Lake Karia while some go to the National Water and Sewerage Corporation Public Water Taps. Some people have lost lives through drowning while fetching water from River Kyambura, especially women and children. It was therefore considered important to construct a safe water supply system to serve villages of Kaberengye A, Kaberengye B and Omukabare A, which are affected by the on-going construction of the Kyambura Hydro Power plant. A number of alternative systems were evaluated with an interest of identifying the most feasible system that can serve the above mentioned communities with safe water. A Solar-powered Deep Production Borehole System was selected as the most viable especially in terms of operation and maintenance for sustainability The objective of the field industrial training were To provide an opportunity to the student to apply principles and techniques theoretically learnt into real life problem solving situations and to get hands on experiences in real life situations that they are expected to work in when they graduate or after accomplishing the degree. The experience were gained importantly in all areas which are explained in chapter two as case studies of Construction of Pumped Water System and the focus for reporting and training was based on the course outline for field report in the course content in relation to experience gained in the field of study. Project Design, contract procedure, Construction procedures, innovations and information technology in rehabilitation of Water Tanks was all trained in addition to project management, Experience was gained in physical planning of Rubirizi District and this was well detailed in case study and experience gained in chapter three.

    Improved road network to ease access to social services and overall economic development : A case study of Kyanyawara and Kiko Wards by filling the Mburru Swamp in Kiko Town Council, Kabarole District
    ( 2019-07) Burolerro, James Happy
    This report was written to find out whether improved road network can lead to significant increase in access to social services and enhanced economic development. A case study was taken from Kiko Town in KabaroleDistrictwhere a swamp was raised to connect villages of Makobyo, Kanyawara, Kasojo and Ibura on the opposite side of the Central Business District to Rwengaju and Mburru on the side of the Central Business District, with the idea of connecting two adjacent collinear roads but with dead ends initiated, planned for and finally executed. The reason was to ensure that there is easy movement that saves time and money as people move from either side, as well as seeing more structures built for both commercial and residential functions, so there is increased human activity along the same stretch in particular and the Central Business District in general. The major problems to the area were: First of all, there were steep slopes in Makobyo and Rwengaju which would not allow motorized transport to take place, which required that they are cut to reduced levels. Secondly, these slopes were joined by a swamp of an average of 400mm wide which was making it hard even for pedestrians to cross from one village to the other, that it required to fill this swamp to allow movement. The hills on both sides of Mburru and Makobyo which share the swamp boundaries, were cut to reduced levels to allow movement of traffic from either side. The cut soils were used to fill the swamp, so as to allow traffic to cross the swamp and also to let water flow in a streamlined manner.People of Makobyo, Mburru and the neighboring villages are able to access service centers that are much concentrated in the central business district of Kiko town council.
