  1. 1. Evaluation of Innovative Rehabilitation Technologies Utilising Polymer Composites for Aging Sewer Systems

    Författare :Parastou Kharazmi; Folke Björk; Tord af Klintberg; Tor Broström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Water and wastewater sewer system maintenance is among the costliest aspects of infrastructure investment. The replacement of deteriorated lines is a difficult and expensive process that causes community disturbance and is generally not conducted fast enough to meet demand. LÄS MER

  3. 2. Aspects of historical data and health criteria for drinking water network replacement strategies

    Författare :Annika Malm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pipe rehabilitation; water distribution network; cost-benefit analysis; Pipe replacement; leakage control; lifetime distribution; pipe failure; health risk; strategic planning; asset management;

    Sammanfattning : The drinking water distribution network represents a major proportion of the investments and capital assets of a water utility. Consequently, qualified insight into future replacement needs provides water utilities with a foundation for financial planning. LÄS MER

  4. 3. Towards a sustainable road infrastructure in an age of digitization: opportunities and challenges

    Författare :Zhuhuan Liu; Nicole Kringos; Romain Balieu; Aikaterini (Katerina) Varveri; KTH; []

    Sammanfattning : Pavement system plays an indispensable role in the socio-economic and sustainable development of every modern society. Yet, pavement construction and maintenance is also responsible for a significant fraction of the GHG emissions from the whole transport sector. LÄS MER

  5. 4. I-girder Composite Bridges with Lateral Bracing : Improved load distribution

    Författare :Victor Vestman; Peter Collin; Robert Hällmark; Hans Petursson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assessment; bridge; composite bridge; steel-concrete composite; I-girder; case study; horizontal trusses; lateral bracing; rehabilitation; strengthening; torsional stiffness; upgrading; Byggkonstruktion; Structural Engineering;

    Sammanfattning : This thesis deals with the subject of lateral bracing between the bottom flanges of I-girder composite bridges. The focus is on the impact of adding lateral bracing on existing bridges, as well as on new bridges. LÄS MER

  7. 5. Analysis of Excavation Damage, Rock Mass Characterisation and Rock Support Design using Drilling Monitoring

    Författare :Jeroen van Eldert; Håkan Schunnesson; Daniel Johansson; David Saiang; Thomas Dalmalm; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blast damage; Excavation Damage Zone; EDZ; Measurement While Drilling; MWD; Rock support; Rock mass characterisation; Tunnelling; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : Prior to an underground excavation a site investigation is carried out. This includes reviewing and analysing existing data, field data collected through outcrop mapping, drill core logging and geophysical investigations. LÄS MER
