1. Inhibition of light-induced colour reversion of wood-containing papers by means of coating
Sammanfattning : The main purpose of this thesis was to find ways to maintain a low level of light‐induceddiscolouration at an increased addition of mechanical and chemimechanical pulps in coated highqualityfine paper and magazine paper grades. Current technology allows the production of highyieldpulps such as thermomechanical and chemimechanical pulps with properties suitable formanufacturing high‐quality paper or paperboard with a low basis weight.

2. Investigations of binder rejuvenation related to asphalt recycling
Sammanfattning : Investigations described in this doctoral thesis concernmaterial behaviour related to asphalt recycling. More indetail, the thesis describes development and application ofmethods for characterisation of the rejuvenation process, inwhich old and new binders are mixed. LÄS MER
3. The influence of ageing on the salt-frost resistance of concrete
Sammanfattning : Abstract This thesis presents the results of an investigation of the influence of ageing on the salt-frost resistance of concrete. The ageing mechanisms investigated were hydration, drying and carbonation. LÄS MER
4. Influence of waxes on bitumen and asphalt concrete mixture performance
Sammanfattning : This doctoral thesis consists of a literature review, presented in two papers, and another six papers describing experimental studies of the influence of different kinds of wax and polyphosporic acid on bitumen and asphalt concrete mixture properties. The literature review should give an extensive description of the field of knowledge concerning wax in bitumen. LÄS MER
5. An investigation into some aspects for foamed bitumen technology
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
