Description

The decohesion process is a pavement rehabilitation technique that is carried out in situ, reusing materials from the existing pavement. The process involves decohesifying the in-place bituminous pavement and mixing it with a predetermined thickness of the underlying granular base, sometimes with the addition of a corrective material (virgin aggregate). The decohesive in-place recycling technique is the most widely used rehabilitation technique in Quebec.

As part of this project, we plan to carry out laboratory studies on the potential use of concrete and steel slag residues as grading correction materials to replace natural aggregates. Ultimately, the overall aim of the project is to maximize the circularity of this rehabilitation technique by avoiding the use of virgin granular materials.
