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. Evaluation of Road Equipment with Emphasis on Condition Assessment

   Author : Sven-Olof Lundkvist; Ulf Isacsson; Rolf Magnusson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road equipment; Condition assessment; State-of-the-art; Mobile measurement; Road marking; Road sign; Post delineator; Traffic light; Street lighting; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

   Abstract : This doctoral thesis deals primarily with condition assessment of road equipment. The road equipment concept is defined by five main groups, road lighting, fences and barriers, vertical signs, horizontal signs and traffic signals, respectively. READ MORE

6. 4. Evaluation of Dust Suppressants for Gravel Roads : Methods Development and Efficiency Studies

   Author : Karin Edvardsson; Björn Birgisson; Andrew Dawson; KTH; []
   Keywords : Gravel road; dust; particulate matter; PM10; horizontal dust diffusion; deteriorations; maintenance; dust control; dust suppressants; efficiency; application rate; leaching; residual concentration; seasonal variations; salt solution; solid salt; calcium chloride; magnesium chloride; lignosulphonate; polysaccharide sugar ; bitumen emulsion; rape oil; starch; surfactant; mesa; clay; fine material content;

   Abstract : Approximately 75 percent (300 000 km) of the total Swedish road network and 20 percent(20 000 km) of the national road network consists of gravel roads. One of the most significantproblems associated with gravel roads is traffic-generated dust emission, which contributes tothe deterioration of the road surface and acts as a major source of particulate matter releasedinto the atmosphere, thereby involving public economics, road safety, human health, andenvironmental quality.

7. 5. Assessment of existing concrete bridges : bending stiffness as a performance indicator

   Author : Markus Bergström; Paulo J. de S. Cruz; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Abstract : Optimizing the use of existing civil reinforced concrete (RC) structures could be interpreted in such a way as to say that the capacity should be used and taken care of in an effective manner, both from a technical and economical point of view, keeping the safety in mind. Achieving this requires thorough understanding of the structure and also of the tools used for assessing current and future capacity and needs. READ MORE
