  3. 7. LCA and LCCA in the design of geotechnical engineering works

    Författare :Ida Samuelsson; Stefan Larsson; Johan Spross; Rasmus Rempling; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment; Life Cycle Cost Analysis; climate impact; costs; geotechnical engineering; Livscykelanalys; Livscykelkostnadsanalys; klimatpåverkan; kostnader; geoteknik; Soil and Rock Mechanics; Jord- och bergmekanik;

    Sammanfattning : Geotechnical engineering works are part of almost all construction and infrastructure projects. The geotechnical engineering work contributes to the impact on the environment and gives rise to costs throughout its life cycle. LÄS MER

  4. 8. Influence of aggregates on permanent deformation of asphalt

    Författare :Bernardita Francisca Lira Miranda; Robert Lundström; Stefan Larsson; Alan Carter; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asphalt; deformation; rutting; gradation; flakiness index; Asfalt; kornstorleksfördelning; flisighetsindex; permanent deformation; spårbildning.; Jord- och bergmekanik; Soil and Rock Mechanics;

    Sammanfattning : One of the most common failure modes for asphalt pavements is the occurrence of permanent deformation on the wheel path. This leads to not only other distresses, such as potholes and stripping, but also decreases substantially road safety and increases maintenance costs. LÄS MER

  5. 9. Probabilistic time estimation in tunnel projects

    Författare :Mohammad Mohammadi; Johan Spross; Fredrik Johansson; Larsson Stefan; Anna Kadefors; Lars-Olof Dahlström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cost overrun; Tunneling projects; Probabilistic approaches; time estimation; Kostnadsöverskridande; tunnelprojekt; sannolikhetsmetoder; tidsuppskattning; Soil and Rock Mechanics; Jord- och bergmekanik;

    Sammanfattning : Transport infrastructure projects, including tunneling, suffer from timedelays and cost overrun. A literature review shows that the effect ofuncertainty has been neglected in explaining time and cost overrunmeaning that technical explanations matter. LÄS MER

  7. 10. Geotechnical risk management using the observational method

    Författare :Mats Tidlund; Stefan Larsson; Johan Spross; Håkan Stille; Jan Bröchner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; risk; risk management; geotechnical engineering; contractual framework; observational method; risk; riskhantering; geoteknik; kontrakt; observationsmetoden; Soil and Rock Mechanics; Jord- och bergmekanik;

    Sammanfattning : There have been many cost overruns, time delays and quality problems reported from geotechnical engineering projects around the world during recent decades. Many of the reported problems are associated with risks related to the geotechnical conditions. LÄS MER
