1. 1. 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
