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

    Författare :Hawzheen Karim; Björn Birgisson; Ulf Isacsson; Rolf Magnusson; Robert Thomson; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : This thesis investigates Swedish trade promotion in Lebanon from 1920 to 1975. The aim is to increase knowledge about how actors in a small open western economy tried to develop their economic interests in an emerging market characterized by great uncertainty. LÄS MER

  4. 3. Improved road design for future maintenance : analysis of road barrier repair costs

    Författare :Hawzheen Karim; Ulf Isacsson; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Tyre/road interaction : A holistic approach to the functional requirements of road surfaces regarding noise and rolling resistance

    Författare :Tiago Vieira; Sigurdur Erlingsson; Ulf Sandberg; Tony Parry; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road; surface; noise; rolling resistance; tyre; mitigation; Vägbeläggning; vägyta; textur; buller; rullmotstånd; däck; Building Materials; Byggnadsmaterial;

    Sammanfattning : Increased fuel consumption, increased greenhouse gas emission, diminishing real-estate prices and increased health issues are some of  the negative effects on the climate, on the environment and on the society from tyre/road rolling resistance and noise. The first two aspects are affected by energy dissipation in the tyre/pavement contact and are related to rolling resistance. LÄS MER

  7. 5. The Rocky Road : Why Usability Work is so Difficult
