• Comparison of practice for aggregate use in road construction — results from an international survey 

      Fladvad, Marit; Aurstad, Joralf; Wigum, Børge Johannes (Chapter, 2017)
      Conventional flexible pavement structures are constructed using aggregates, in a combination of unbound and bitumen bound materials. Crushed rock aggregates are fundamental for road construction in many countries. This ...
    • Influence of jaw crusher parameters on the quality of primary crushed aggregates 

      Fladvad, Marit; Onnela, Tero (Journal article; Peer reviewed, 2020)
      A parameter study using a jaw crusher is designed to investigate the influence of feed gradation, feed rate, crusher setting and crusher speed on the crusher operation and the quality of the produced aggregates. The study ...
    • Kontinuerlig komprimeringskontroll 

      Fladvad, Marit (Master thesis, 2012)
      Komprimering av granulære materialer kan ha stor innvirkning på en vegs levetid, og komprimeringskontroll er derfor en viktig del av kvalitetskontrollen ved vegbygging. Formålet med denne oppgaven er å undersøke om man ved ...
    • Large-size aggregates for road construction – a review of standard specifications and test methods 

      Fladvad, Marit; Ulvik, Arnhild (Peer reviewed; Journal article, 2019)
      Construction aggregates are essential structural components in road structures, whether in unbound form or combined with cement or bitumen. Specifications and test methods for aggregates are standardised, but current ...
    • Metodestudium av micro-Deval for alternative fraksjoner 

      Mathisen, Simen (Master thesis, 2022)
      Den europeiske standarden for bestemmelse av motstand mot slitasje ved bruk av micro-Deval, EN 1097-1, er under revisjon. I et høringsutkast for denne revisjonen, prEN 1097 1, er det beskrevet to nye metoder som omhandler ...
    • Optimal utilisation of unbound crushed aggregates for road construction 

      Fladvad, Marit (Doctoral thesis, 2020)
      Aggregates are construction materials produced from non-renewable rock resources. Because high-quality aggregate resources have limited availability, utilisation of aggregates should be considered carefully to prevent ...
    • Performance of Unbound Pavement Materials in Changing Moisture Conditions 

      Fladvad, Marit; Erlingsson, Sigurður (Chapter, 2020)
      Expected climate changes will in many areas represent a shift towards increased precipitation and more intense rainfall events. This may lead to increased moisture within road structures and possible overloading of road ...

      Alnæs, Lisbeth-Ingrid; Danielsen, Svein Willy; Onnela, Tero; Wigum, Børge Johannes; Hoff, Inge; Barbieri, Diego Maria; Mathisen, Lillian Uthus; Fladvad, Marit; Nålsund, Roar (Research report, 2019)
      Kortreist Stein har hatt en arbeidspakke konsentrert mot Produksjon og anvendelse. Som et utgangspunkt for forskningsaktivitetene, er det det laget detaljerte oversikter over de mest relevante anvendelsesområdene for ...
    • Utilization of unbound aggregates for road construction 

      Fladvad, Marit (Journal article; Peer reviewed, 2017)
      Crushed rock aggregate is a non-renewable resource of great interest in road construction and other branches of the construction industry. To prevent resource scarcity, utilization of aggregates should be considered carefully.
