Controlled density fill (CDF) is a low strength concrete that can be used as backfill or sub-base. Properties of this mix design vary but include characteristics which allow the material to flow into large trenches or [be] used as pipe encasement. Additionally, since these materials do not require select raw materials in order to produce high compressive strengths, a wide variety of recycled materials can be used in these types of mixes, including plastics, tire rubber and even styrofoam.

CONT

Dans certains cas particuliers où on veut obtenir une meilleure capacité portante pour de plus grandes hauteurs de remblai, il est possible d'avoir recours à des assises où le remblai situé dans le quart inférieur du tuyau est composé d'un remblai sans retrait. Un remblai sans retrait est un matériau de remblayage à densité contrôlée, c'est-à-dire que la densité du matériau n'exige aucun compactage pour obtenir une capacité de support suffisante.
