Optimization of Pavement Design Using Recycled Plastic Waste for Sustainable Road Construction in Uganda.

Authors: Kiddu Kawuki Andrew1 , Nkwasibwe Kenneth2

Published on 01 Jan 1970

The study examined the Optimization of Pavement Design Using Recycled Plastic Waste for Sustainable Road Construction in Uganda with the aim of enhancing pavement performance while addressing the environmental challenge of plastic waste accumulation. The research specifically sought to characterize and optimize the material properties of plastic-modified bitumen using locally sourced recycled plastic waste and Ugandan bitumen; to evaluate the mechanical performance and durability of the optimized plastic-modified asphalt concrete mix under simulated Ugandan environmental and traffic conditions; and to assess the technical, economic, and environmental feasibility of implementing the optimized pavement design for large-scale adoption in Uganda. Laboratory experiments were conducted using penetration, softening point, ductility, specific gravity, and flash point tests on both conventional and plastic-modified bitumen at varying plastic contents of 5%, 10%, and 15%.

Assessment of the Impact of Green Building Materials on Structural Sustainability in Urban Construction Projects.

Authors: Kiddu Kawuki Andrew1 , Nkwasibwe Kenneth2

Published on 01 Jan 1970

The study examined the Evaluation and Integration of Green Building Materials (GBMs) for Sustainable Construction in Uganda with the aim of assessing their mechanical, environmental, and socio-economic performance and developing strategies for their adoption. The objectives were to quantitatively evaluate the mechanical and physical properties of selected local GBMs, to assess the environmental and economic viability of GBM-based structural systems through Life Cycle Assessment (LCA) and Life Cycle Cost Analysis (LCCA), and to identify key perceived barriers and drivers influencing GBM adoption among construction professionals, ultimately developing a strategic framework for their integration into urban building codes. Laboratory experiments were conducted on stabilized earth blocks, bamboo composites, compressed agricultural panels, and recycled concrete aggregates to determine compressive strength, flexural strength, water absorption, thermal conductivity, and density.

Design And Performance Analysis Of A Solar-Powered Water Pumping System For Rural Communities.

Authors: Kiddu Kawuki Andrew1 , Nkwasibwe Kenneth2

Published on 01 Jan 1970

The study examined the Design, Performance, and Economic Feasibility of a Solar-Powered Water Pumping System for Rural Communities in Uganda. The objectives were to design and simulate a solar-powered water pumping system optimized for local hydrological and solar conditions, to empirically evaluate the system’s technical performance over a 12-month period, and to conduct a comprehensive economic analysis comparing its life-cycle costs to a conventional diesel-powered alternative. The system was designed using a 3.

Evaluation Of Predictive Maintenance Techniques For Reducing Equipment Downtime In Manufacturing Industries In Uganda

Authors: Mukiibi Zacharia1 , Kalema Abdullah2 , Mwesiga Caleb3

Published on 01 Jan 1970

The study investigated the prevalence, effectiveness, and contextual factors influencing maintenance strategies in manufacturing firms in Uganda, with a particular focus on predictive maintenance (PdM). The objectives were to identify the current prevalence and sophistication of maintenance strategies, to quantitatively evaluate the impact of PdM techniques on equipment downtime, and to analyze the critical success factors and barriers affecting the effective implementation of PdM programs. Data were collected from 80 manufacturing firms using structured questionnaires, interviews, and equipment performance records.

Development Of An Intelligent Energy Management System For Smart Homes Using Iot Technology.

Authors: Eletu Joshua1 , Managen Amosi2 , Kiddu Kawuki Andrew3

Published on 01 Jan 1970

The study investigated the design, development, and evaluation of an IoT-based Intelligent Energy Management System (IEMS) aimed at optimizing energy utilization in rural and semi-urban settings in Uganda. The objectives were to design a functional and cost-effective hardware system for real-time energy monitoring, develop robust decision-making algorithms to optimize energy source selection among solar, grid, and battery, and quantitatively evaluate the system’s impact on critical energy performance metrics. The hardware prototype demonstrated high accuracy in monitoring key parameters, including voltage, current, power consumption, solar generation, and battery state-of-charge, with measurement accuracy consistently above 95%.

Design And Simulation Of A Low-Cost Solar Microgrid For Off-Grid Rural Electrification.

Authors: Eletu Joshua1 , Managen Amosi2 , Kiddu Kawuki Andrew3

Published on 01 Jan 1970

This study designed and simulated three low-cost solar microgrid architectures to address the critical challenge of offgrid rural electrification in Uganda. The primary objective was to identify the most techno-economically viable and sustainable configuration for a model community of 100 households. The methodology involved modeling three distinct systems a PV-battery system (Microgrid A), a PV-battery-diesel hybrid (Microgrid B), and a PV-wind-battery hybrid (Microgrid C) using the HOMER Pro software, with analysis based on local solar resource data, detailed load profiling, and sensitivity analyses for key variables like fuel cost and component pricing.
