Uppföljning av vägar utförda med KGO III-metoden: slitlagerbeläggningar
2008 (Swedish)Report (Other academic)
The positive effects that have been established from the laboratory tests performed on cored samples from pavement surface layers laid according to the KGO III method, compared with reference pavements three years' remain after traffic. Results from field measurements according to noise, friction, texture and rut depth, performed directly after compaction and after three years' traffic show that KGO III pavement performed well compared to the reference pavement. Also laboratory tests on cored samples show that KGO III pavements after three years' traffic still have good durability, tested through stiffness modulus and wear resistance before and after a special winter condition method developed at VTI. The mix procedure, called flow mixing procedure, in the KGO III concept, gives a more homogenous mix with thicker mastic (binder + fine aggregate) film around coarse aggregates. This enables manufacturing of bituminous mixes at lower temperature and with lower binder content, which gives qualitative, environmental and economical advantages. The contractors of the Swedish Road Administration have during the period 1998-2006 manufactured over 500 000 tone bituminous mixtures with this methodology, mostly surface layers.
