1. 1. On investigation of stripping propensity of bituminous mixtures

   Författare :Umaru Bagampadde; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In this study, an experimental programme was designed toestablish a relationship between bituminous mixture constituentmaterial properties and their propensity to moisture induceddamage in form of stripping. Six bitumen types (3 from Ugandaand 3 from Sweden) with presumably varying characteristics wereevaluated basing on rheology and chemistry. LÄS MER

3. 2. Investigations on moisture damage-related behaviour of bituminous materials

   Författare :Umaru Bagampadde; Ulf Isacsson; Manfred Partl; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture damage; State-of-the-Art; Stripping; Moisture sensitivity; Bituminous materials; Construction engineering; Konstruktionsteknik;

   Sammanfattning : This doctoral thesis presents results of literature review on classical and contemporary aspects of stripping, as well as experimental investigations on moisture damage as influenced by bituminous materials. Previous research in the area of moisture damage was reviewed and synthesized into a state-of-the-art. LÄS MER

4. 3. An investigation into some aspects for foamed bitumen technology

   Författare :May Namutebi; Björn Birgisson; Alvaro Guarin; Umaru Bagampadde; Baoshan Huang; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Foamed bitumen; Binder ageing; Aggregate coating; Compaction; Mix design; Aggregate porosity; Civil and Architectural Engineering; Byggvetenskap;

   Sammanfattning : Despite applications of foamed bitumen technology in pavement construction in various places around the world, there are still several aspects about this technology that are not clear. In addition, knowledge on foamed bitumen technology is mainly empirical and lacks scientific basis. LÄS MER

5. 4. Some Aspects of Foamed Bitumen Technology

   Författare :May Namutebi; Björn Birgisson; Umaru Bagampadde; Jonas Ekblad; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Foamed bitumen; Aggregate coating; Rice density; Foam characteristics; Surface energy; Locking concept; Gyratory; Compaction; Optimum moisture content; Other civil engineering and architecture; Övrig samhällsbyggnadsteknik och arkitektur;

   Sammanfattning : Although foamed bitumen has been widely applied in pavement construction some of its aspects are still not yet understood. In this study, some of these aspects including: effects of the foaming process on binder chemistry, characterization of foamed bitumen and development of a rational method to optimize foam characteristics, evaluation of aggregate particle coating within foamed bitumen treated materials, and development of a gyratory compaction procedure for laterite gravels treated with foamed bitumen were addressed.
