Nordic test methods for bituminous base course stabilization. State of the art report

Bitumia sisaltavien kerrosstabilointien pohjoismaiset testausmenetelmat. Nykytilaselvitys

The aim of the research was to determine the best practice for bitumen stabilizations in the Nordic countries. The research was focused mostly on methods reported in Norway and Sweden. Methods followed in Iceland are mostly the same as in Norway. In Denmark no stabilization has been used except some trials. Terminology of stabilization materials (recycling mixtures based on cold technology) and technology based on them varies in different countries, which makes it difficult to handle the thing in a uniform way. The study was limited to foam bitumen and bitumen emulsion stabilization materials specified in the Finnish way. Some data was also enclosed about a remix-like method from Sweden. Results have also been shown about composite stabilization follow up studies of trials in Sweden. (A composite stabilization containing both bituminous and hydraulic binder in the same layer). In Norway road structures have been strengthened for many years using a cold technology in the same way as in Finland. Norway has established uniform terminology and production methods. At the end of 1990's Norway had an active research and development phase of cold technology based construction methods. In the AUT-project (Asfaltutviklings-prosjektet i Telemark) from 1994-97 many test methods were developed for mix design of cold mixes in Norway. The Finnish part of this research includes a short review of Finnish mix design method for stabilizations and earlier studies about composite stabilizations. Additional statistics about stabilizations made in Finland from 2000-06 are given.
