Abstract
The lightweight embankment (1) comprises blocks (3) stacked in successive layers, the blocks of the same layer being separated by gaps (7). The blocks can in particular be made of expanded polystyrene. Application to embankments to support roads.
Claims26
An embankment, having a density less than 2000 kg/m.sup.3, comprising blocks stacked in successive layers, wherein:
- each of said blocks has a substantially parallelepipedal elongated general shape and a respective longitudinal axis and two respective longitudinal side faces;
- said layers comprise a first layer having first said blocks, the longitudinal axis of each of said first blocks being oriented along a first general direction;
- at least two of said first blocks are separated along respective opposed longitudinal side faces by a gap;
- said layers comprise a second layer laid on said first layer and having second said blocks;
- the longitudinal axis of each of said second blocks is oriented along a second general direction substantially perpendicular to said first general direction;
- and
- at least one of said second blocks is laid across said gap.
