  2. 1. Improved road design for future maintenance : analysis of road barrier repair costs

    Author : Hawzheen Karim; Ulf Isacsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; highway maintenance; highway management; highway design; road planning; road design; highway engineering; road barrier; cable barrier; w-beam barrier; road barrier damages; barrier repair cost.; Building engineering; Byggnadsteknik; Vägprojektering för minskade drift- och underhållskostnader;

    Abstract : The cost of a road construction over its service life is a function of the design, quality of construction, maintenance strategies and maintenance operations. Unfortunately, designers often neglect a very important aspect which is the possibility to perform future maintenance activities. READ MORE

  4. 2. Road Design for Future Maintenance : Life-cycle Cost Analyses for Road Barriers

    Author : Hawzheen Karim; Björn Birgisson; Ulf Isacsson; Rolf Magnusson; Robert Thomson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road maintenance; road management; road planning; road design; life-cycle cost; road barrier; guardrails; cable barrier; road traffic injuries; barrier collisions and barrier repair costs.; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; Vägprojektering för minskade drift- och underhållskostnader;

    Abstract : The cost of a road construction over its service life is a function of design, quality of construction as well as maintenance strategies and operations. An optimal life-cycle cost for a road requires evaluations of the above mentioned components. READ MORE

  5. 3. Solar energy for a brighter life. A case study of rural electrification through solar photovoltaic technology in the Eastern Province, Zambia

    Author : Mathias Gustavsson; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rural development; rural electrification; distributed generation; photovoltaic technology; solar home system; energy services; Zambia; Sub Saharan Africa;

    Abstract : Electricity is taken for granted in many parts of the world. In Sub-Saharan Africa, typically less than 5% of the rural population have access to this energy source. Even though electricity in itself does not lead to development, it can support a development process. READ MORE
