1. 16. 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

3. 17. Reliability-based Design Procedure for Flexible Pavements

   Författare :Yared Hailegiorgis Dinegdae; Björn Birgisson; Nicole Kringos; Nils Rydén; William Buttlar; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Top-Down fatigue cracking; asphalt mixture morphology; fracture mechanics; response surface; reliability analysis; load resistance factor design; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : Load induced top-down fatigue cracking has been recognized recently as a major distress phenomenon in asphalt pavements. This failure mode has been observed in many parts of the world, and in some regions, it was found to be more prevalent and a primary cause of pavements failure. LÄS MER
