Base course stabilization development project INFRA-STABIL. Summary report

The project "Service life and product approval of base course stabilizations - Infra-Stabil" was carried out during 2004-2007. This Summary report includes its essential results. The study consisted of three parts: 1) Development of bituminous base course stabilization 2) Full scale trials with stabilized road bases 3) Development of base course stabilization service life evaluation and product approval. The results of the project are shown in six different reports, which have been published on the internet site of the Finnish Road Administration: www.tiehallinto.fi. The Summary report has been published both as a paper publication and on the internet in English and in Finnish. In Finland base course stabilization is usually made using existing raw material from the construction site and this will set definite limitations for following exact recipes of mix composition. However, a successful stabilization result requires that the stabilization method is chosen based on the properties and conditions of the road, also assuming enough time has been allowed for preliminary planning, the mix composition stays in the defined area and that the stabilization course is compacted properly. The essential results of the project were: a) changing the mix compositions (gradation and binder content), b) identifying that anti-stripping agent must usually be used in a foam stabilization mixture, c) changing methods in specimen preparation and mix design, d) changing test methods, e) confirming the dominating effect of compacting to quality both in the laboratory and on site, f) identifying that the number of freeze-thaw cycles has a significant effect on the stiffness modulus and consistency of deformation resistance, g) producing research material for the basis of the requirements readjustment for stabilizations, h) obtaining reference data for possible product approval studies of stabilizations, i) developing service life evaluation methods for stabilizations. The essential results of the project were taken into account in the construction specifications at the same time as the research project was completed.
