1. 6. Dry Classification of Fine Aggregates for Concrete and Asphalt

   Författare :Robert Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; asphalt; classification; aggregate;

   Sammanfattning : Aggregate is defined as particles of rock which in combination are used as a civil engineering material. It is used in bounded form in asphalt and concrete. Historically natural sand has been used as fine aggregate for concrete production in Sweden. LÄS MER

3. 7. Investigation of asphalt compaction in vision of improving asphalt pavements

   Författare :Ehsan Ghafoori Roozbahany; Manfred N. Partl; Gabriele Tebaldi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold asphalt pavement joints; asphalt joint laboratory production; IDT joint evaluation; DTT joint evaluation; 4PB joint evaluation; joints FEM analysis. Discrete Element Modeling DEM ; X-ray Computed Tomography CT ; Compaction Flow Test CFT ; Compactability;

   Sammanfattning : Asphalt joints are potentially weakest parts of every pavement. Despite of their importance, reliable tools for measuring their mechanical properties for design and performance assessments are still scarce. LÄS MER

7. 10. Modeling frost heave damages throughout the asphalt layer

   Författare :Saeed Vosoughian; Romain Balieu; Inge Hoff; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asphalt pavement; Frost heave; Viscoelastic damage model; Thermomechanical approach.; Asfaltbeläggning; tjällyft; viskoelastisk skademodell; termomekanisk ansats.; Bro- och stålbyggnad; Structural Engineering and Bridges;

   Sammanfattning : There are various distresses arising from traffic loads and the surrounding environment to whichan asphalt pavement is subjected during its life span. The environment-associated damages aremore severe during winter when abundant moisture and freezing temperature are presentsimultaneously. LÄS MER
